The different phases may last for varying periods of times from several years in anagen, to a few months in telogen or several weeks in anagen. Fortunately not all hair follicles are in the same phase at the same time. So the majority of the follicles will be in anagen phase, while a smaller amount will be in the catagen phase and a few follicles will be in the telogen phase. This ensures that there is always some hair present even when the follicle is not active and the hair is not growing.

Why am I losing my eyebrows or why are they falling out and not growing back? Is it a kind of brow disease? I have or could it be my over-plucking? Discover all the reasons why your eyebrows are thinning or falling out including over-plucking, eczema, thyroid problems, and chemotherapy among others. We will also cover treatments and ways to regrow your eyebrows back.

For women going through menopause, the cause of hair loss is almost always related to hormonal changes. However, there are many other factors that can contribute to hair loss during menopause. These include extremely high levels of stress, illness, or a lack of certain nutrients. Diagnostic blood tests that can help rule out other causes of hair loss include thyroid tests, and/or a complete blood count.


Male pattern hair loss has been established as androgen-dependent because it is associated with changes in the androgen receptor and responds to antiandrogen therapy (Ellis et al., 2002). With FPHL, genes that encode aromatase, which converts testosterone to estradiol, are also implicated (Yazdabadi et al., 2008, Yip et al., 2009). The process of androgen biosynthesis is depicted in Figure 1.

If you’re losing more than 100 hairs a day it may be worth seeking the help of a hair loss professional. Oestrogen and hair loss may or may not be problematic but there is still the chance that your hair follicles may become damaged in the process. There is currently no concrete evidence that links an increase in oestrogen to the effective treatment of hair loss, but there are hair loss treatments that have FDA-approval for the specific purpose of regrowing hair. Topical products like minoxidil are proven to promote hair growth and there are also anti-androgen products that could help to deflect the creation of DHT. Early treatment is the key to successful hair restoration so if you’re concerned, contact the Belgravia Centre to ensure that you will keep your head of hair full, healthy, and strong.


Trichotillomania is a hair pulling disorder associated with anxiety, stress, depression, boredom and frustration. It is where a person manually removes hairs with their finger, either a few strands throughout the day or sometimes many strands at one time during an emotional outburst. This behavior is usually a means of coping with stress or emotional turmoil. However, it can sometimes become a habit that is difficult to break. The eyebrows is a commonly targeted area as is the scalp.
Well, maybe that’s a new adage from instagram, but it’s true all the same: eyebrows are the essential defining feature of every woman’s face. That’s exactly why eyebrow loss can feel like a death sentence to the beauty-conscious woman. With thick, lush eyebrows in style, eyebrow loss can feel more traumatizing than ever. Hair one day, gone the next!

Thallium poisoning should be suspected in any patient manifesting nervous system and gastrointestinal symptoms along with alopecia. The hair loss affects the scalp, periocular hair, limbs, and sometimes the axillae. Examination of the hair roots under a microscope using polarized light shows distorted anagen roots and several black zones in continued poisoning.[118]

While you wait for your doctor’s recommendations to take effect, you can mask the problem with a high-quality eyebrow gel. Unlike eyebrow pencils that can lead to a brow that looks drawn on, an eyebrow gel enhances your eyebrow shape with a soft color and strong hold. We like Laura Mercier Eye Brow Gel, available at Nordstrom for $20. Prior to using the gel, pencil in small sections of the brow that may be entirely bare of hair. Using a pencil sparingly will prevent a brow line that’s too harsh for your face.

This plant is native to North America and has been used for centuries by indigenous people to treat menstrual and menopausal disorders. While modern research results are mixed, some studies do indicate that black cohosh can be effective as a treatment in menopause. While the research focuses on hot flashes and other symptoms of menopause that get more attention than hair loss, it follows that black cohosh could also help to improve hair growth when estrogen levels decline.
It’s natural for estrogen levels to fluctuate throughout a woman’s life, but drastic drops can disrupt the hair growth cycle and cause telogen effluvium. For example, during pregnancy, a woman’s estrogen levels are at their peak. Fewer hair follicles enter the telogen stage of the hair cycle, so hair looks thicker than usual. A few months after pregnancy, however, estrogen levels drop and the excess hair falls out. While totally normal, this type of telogen effluvium can be very upsetting for new mothers.
The normal cycle of hair growth lasts for 2 to 6 years. Each hair grows approximately 1 centimeter (less than half an inch) per month during this phase. About 90 percent of the hair on your scalp is growing at any one time. About 10 percent of the hair on your scalp, at any one time, is in a resting phase. After 2 to 3 months, the resting hair falls out and new hair starts to grow in its place.
Optimal levels of estrogen help to grow full thick hair, while low estrogen levels lead to thin and stalled hair growth, which eventually leads to hair loss. Through the years, a women will go through various cycles of highs and lows in estrogen levels. Puberty is typically associated with high estrogen levels as a woman starts to cycle through menstruation. Pregnancy typically increases hormone production, but once the baby has been delivered the mother can experience a drop in estrogen levels, which can result in thinning and loss of hair. Typically, this corrects itself as the woman's body heals and hormonal regulation returns to normal.  The largest decline in estrogen levels is during menopause. Estrogen is secreted through the ovaries and adrenal glands. When a woman hits menopause, the ovaries’ estrogen production is significantly diminished, which puts an excess burden on the adrenals to produce it. However, as the adrenals are typically overburdened due to stress, symptoms of menopauses like hair loss and hot flashes occur prematurely and excessively for some. Nourishing the body and balancing stress levels will support gentle and graceful transitions.  

No one wants to lose their hair, but for women it is especially traumatic. Men can shave their heads and look hip, even sexy. Most women don’t want to be bald. Though it is more common — and visible — in men, many women lose their hair. According to the American Academy of Dermatology, 30 million women in this country have hereditary hair loss, compared with 50 million men. But many additional women experience thinning hair that results from menopause or health problems. 

"Dr. Yaker was extremely personable as well as knowledgeable on hair and hair health. With his treatment plan that was tailored to my needs and requests, I have noticeable thicker and fuller hair within three months! His enthusiasm towards his work was very comforting. He truly puts the patient at the center of care he delivers and it doesn't go unnoticed! I would highly recommend him as your physician if you are struggling with the appearance of your hair!"
Postpartum hair loss is related to the drop in estrogen experienced after giving birth. During pregnancy, the body has higher levels of estrogen (and progesterone) and estrogen increases hair’s “resting phase,” or the time hair stays on your head before naturally falling out (which is what accounts for the 100 or so hairs that healthy heads shed every day). When estrogen drops after pregnancy, all the hair that had been “resting” starts to shed. Post-pregnancy hair loss is usually temporary, lasting for several months.
This article was very informative for me. I am a 56 yr. old male struggling with high estrogen levels and low T. My last blood test taken last week my estrogen level was 100 and my T was 700 its climbing because I am taking testosterone inj. Twice a week at 50mg per inj. I’m also taking Anastrozole 1/10 tab 5 days a week. I just started on that. Its only been 2 days for the estrogen blocker. My belly fat is increasing and I’m feeling and looking extremely bloated. I’m depressed because of the weight gain and the way I now look. My healthy weight is 153 I’m 5’8″ but now I’m 178lbs. I’m also constipated and feel there is a lot of food not passing through, please let me know which part of this is normal and will the Anastrozole start working gradually and cut my belly fat out? My diet is high fiber, low carbs. I am working on working out more often. I’m a non smoker and non drinker.

Other drugs commonly attributed to causing madarosis are miotics, anticoagulants, anti-cholesterol drugs, antithyroid drugs, propranolol, valproic acid, boric acid, and bromocriptine.[21,99] Anticoagulants in high doses have been found to produce loss of scalp, pubic, axillary, and facial hair with loss of eyebrows after a latent period of a few weeks of treatment with dextran and heparin.[100] Propranolol can cause diffuse alopecia along with loss of eyebrows due to telogen effluvium,[101] usually after three months of therapy.[44] Loss of medial aspect of eyebrows can be seen in fetuses exposed to valproic acid.[102] Diffuse alopecia including that of eyebrows has been described due to chronic ingestion of mouthwashes containing boric acid. There was complete reversal following stopping the practice.[103] Levodopa has been noted to cause severe diffuse alopecia within three months of daily use.[104] Hair loss can occur soon after starting topical minoxidil therapy (due to detachment of club hairs following resting hairs reentering anagen), and after cessation of therapy (due to telogen effluvium).[98]
Giorgos Tsetis: Another reason Unilever was inspired to partner with us is that we really target three channels. Direct-to-consumer is one, then we target physician channels and salon channels; which are the hardest to convince. There's liability involved, so there's no doctor in the world who is going to recommend or endorse a product they don't believe in. We have about 350-400 physicians currently selling the product. A large amount of these doctors are thought-leaders or experts in the space, so they are known to speak about this issue on a world stage when it comes to new innovations. We also have each of the top 20 hair salons in the country carrying the product. There's a ton of celebrities who use the product as well. It is a premium product, but we've still made it affordable for people. When you look at other products on the market, our price point is comparable. We're also working on special programs for people in need who can't normally afford the product. If somebody is motivated, serious and really needs it -- we work to make sure they can get the product, and seek to serve as many people as possible.

The hormonal process of testosterone converting to DHT, which then harms hair follicles, happens in both men and women. Under normal conditions, women have a minute fraction of the level of testosterone that men have, but even a lower level can cause DHT- triggered hair loss in women. And certainly when those levels rise, DHT is even more of a problem. Those levels can rise and still be within what doctors consider "normal" on a blood test, even though they are high enough to cause a problem. The levels may not rise at all and still be a problem if you have the kind of body chemistry that is overly sensitive to even its regular levels of chemicals, including hormones.


If you’ve undergone chemotherapy recently, you know the effects that it has on your hair, including your brows and lashes. First of all, I want to point you to this awesome resource by FairyHairs (click here), that shows in intervals, with pictures, what you can expect with regrowing your hair after chemo (Thank you, Jenny Mealy!). The article also includes ways to regrow your hair after chemo.
If you’re in good health but would like your brows to be a bit fuller, you’ve got plenty of options. Massage a bit of moisturizing coconut oil into your eyebrows about three times weekly, to make for healthier, shinier and more eye-catching hair. Eyebrow pencils remain an effective choice as a go-to filler; go a shade lighter than your brows for a natural look. To shake things up a bit, opt for a brow shadow. These powders, which look like eye shadow, go on with a brush and fill in thin or patchy brows with a soft and subtle fullness.

Hair loss in women is not easy to diagnose because it is very often multifactorial in etiology and thus requires well-designed specific steps so that the patient is evaluated properly. The best way to do this is to evaluate the patient in person (rather than sending photos via email or Skype) because the patient gets a chance to meet her doctor to permit the development of a trusting relationship- critical because very often the treatment of hair loss is an involved process that requires a strong doctor-patient relationship.

Thyroid Dysfunction: Since the thyroid gland regulates many body functions by releasing hormones, any disruption in its functioning can cause loss of hair, including eyebrow hair. If your thyroid is underactive, it could cause you to lose the outer third of your eyebrow. The only way to treat thyroid dysfunction is through medication. However, there’s still no guarantee that your eyebrow hair will grow back.


Female pattern hair loss is the most common cause of hair loss in women and one of the most common problems seen by dermatologists. This hair loss is a nonscarring alopecia in which loss occurs on the vertex scalp, generally sparing the frontal hairline. Hair loss can have significant psychosocial effects on patients, and treatment can be long and difficult. The influence of hormones on the pathogenesis of female pattern hair loss is not entirely known. The purpose of this paper is to review physiology and potential hormonal mechanisms for the pathogenesis of female pattern hair loss. We also discuss the current hormonal and hormone-modifying therapies that are available to providers as they partner with patients to treat this frustrating issue.

Changing the shape, thickness and length of the eyebrow is a commonly practiced beauty technique. Some people even remove the eyebrow entirely only to replace it with a pencil-drawn mark (eyebrow pencil). As with any part of the body, repeated irritation can eventually lead to hair loss. Sometimes this is due to manual trauma, chemicals from cosmetics or even infections that arise when breaks in the skin occur. While eyebrow modification will not stop as a commonly practised beauty technique, it should at least be minimized.

There are a couple of other reasons why soy is a great choice too. For one, it is really good for you, protecting your cardiovascular health by reducing your LDL cholesterol levels. For another, soy is an easy, cost-effective choice. Instead of searching everywhere for quality herbal supplements you are unfamiliar with, you can simply add some soy milk to your diet or eat some tofu.
The WHI was a very large, very prominent long-term study which looked at the health effects of HRT. While the study did find a few benefits (women who used HRT had fewer hip or bone fractures and were less likely to develop colorectal cancer), it found a number of risks, including an increased chance of heart attack, stroke, cancer, and blood clots.
Despite the name androgenetic alopecia, the exact role of hormones is uncertain. It is well known that androgens affect the growth of the scalp and body hair and even Hippocrates observed 2,400 years ago that eunuchs did not experience baldness (Yip et al., 2011). However, hyperandrogenism cannot be the only pathophysiologic mechanism for FPHL because the majority of women with FPHL neither have abnormal androgen levels nor do they demonstrate signs or symptoms of androgen excess (Atanaskova Mesinkovska and Bergfeld, 2013, Schmidt and Shinkai, 2015, Yip et al., 2011). Furthermore, cases have been reported in which FPHL developed in patients with complete androgen insensitivity syndrome or hypopituitarism with no detectable androgen levels (Cousen and Messenger, 2010, Orme et al., 1999).
Eyebrows frame your face and play an important role in your facial appearance and expressions. If the hair in your eyebrows starts falling out, you are sure to see a difference in your appearance, which you may want to rectify. Many conditions can cause eyebrow loss.[1] However, you can usually take steps to reverse the effects, such as eating a healthy diet and adjusting your beauty routine or lifestyle to account for the natural aging process.
Dutasteride is a 5-alpha-reductase inhibitor that binds both types I and II enzymes. Compared with finasteride, its inhibition of type II enzymes is three times more potent; its inhibition of type I enzymes is 100 times more potent (Clark et al., 2004). Dutasteride is not approved for the treatment of FPHL by the FDA, and ongoing studies on the efficacy of the inhibitor are promising but largely focus on male patients (Gupta and Charrette, 2014, Olsen et al., 2006). A study of women after 3 years of therapy showed that dutasteride may be more effective than finasteride in women under 50 years of age as measured by hair thickness (not hair density) at the center and vertex scalp (Boersma et al., 2014). One case report of a 46-year-old female with FPHL showed some response after 6 months of treatment with a dose of 0.5-mg dutasteride daily despite a minimal response to treatment with finasteride and minoxidil (Olszewska and Rudnicka, 2005). Data with regard to the treatment side effects in women is extremely limited. Dutasteride is classified as pregnancy category X because of teratogenicity and should have the same theoretical risk of breast cancer as mentioned in relation to finasteride (Kelly et al., 2016).

Madarosis is the hallmark of lepromatous leprosy. It was reported in 76% of patients with multibacillary leprosy.[76] Bilateral symmetric cicatricial madarosis occurs in lepromatous leprosy due to histiocytic infiltration of hair follicles[77,78] [Figure 4]. It occurs in multibacillary leprosy after at least 5 to 10 years of untreated disease.[79] Loss or atrophy of the eyelashes may follow. Madarosis adds to the cosmetic disfigurement caused by leprosy. Absence of madarosis is a good prognostic sign in long-standing cases.[80] Unilateral madarosis may occur in tuberculoid leprosy due to the facial patch in the eyebrow region. In tuberculoid leprosy, madarosis occurs due to granulomatous infiltration of hair follicles leading to their destruction.


There are numerous nonsurgical treatments that when combined, can offer significant hair improvements. Dr. Yaker’s TCHR Volumizing Glycolic Acid Shampoo and Conditioner help restore vitality to the hair by deep cleaning the scalp and reestablishing lost moisture content and physiological pH to the scalp and hair. Dr. Yaker has also formulated his own oral supplement, which is a blend of Aminoplex hair repair vitamins. This is made up of amino acids (building blocks of protein) that produce keratin, which makes up close to 97% of our hair. In addition, Dr. Yaker’s specially compounded FDA approved topical medication, Minoxidil (brand name: Rogaine®), is clinically proven to help slow down, stop and even reverse hair loss in women. Other nonsurgical therapies offered are Low Level Laser Therapy (LLLT) using the advanced LaserCap®, and Platelet Rich Plasma (PRP) with placenta-derived extracellular matrix therapy to help restore thinning hair. Lastly, Dr. Yaker offers scalp and facial micropigmentation where permanent ink is applied to the skin, creating micro dots that replicate the natural appearance of hair. This is used for the scalp and eyebrows.
Around 30 million U.S. women will experience hereditary hair loss, or female pattern baldness (androgenetic alopecia), while others will struggle with situational hair loss, brought on by medical conditions, medications, poor health and nutrition, environmental factors such as smoking and sun damage, or even from adverse reactions to hair care products or treatments.
Madarosis has also been described in phthiriasis of the eyelid. Phthiriasis palpebrarum is the term used to denote infestation of the eyelashes by the pubic louse or Phthirus pubis, also known as crab louse. The parasite is usually transmitted by sexual contact or through fomites. Heavy infestation may result in involvement of axillae, eyebrows, and scalp. When eyebrows and lashes are involved, blue-gray macules or maculae caeruleae may be found on the shoulders, arms, and trunk.[89] The louse can be identified under the microscope as having a wide body and strong second and third pair of legs.[90]
Infestation with the mite D. folliculorum which inhabits the eyelashes is well known. Two species are known to inhabit human beings—D. folliculorum and Demodex brevis.[29] It might either be asymptomatic or may cause symptoms of blepharitis. Kemal et al. report an overall prevalence of 27.4% in their study group.[88] Gao et al. have reported a 100% prevalence of the mite when there is cylindrical dandruff.[29] Patients with demodicosis can develop madarosis.[29]
Additionally, two other considerations are important for a patient who receives treatment for FPHL. First, there is a set of reasonable expectations in patients. Maintaining the current hair density can be considered a successful treatment because women tend to have further thinning as they age (Harfmann and Bechtel, 2015). Second, it is important to ensure that patients understand that progress is slow, and months or years can be required to see a significant improvement (Boersma et al., 2014, Yeon et al., 2011). In our practice, we wait at least 6 months to assess treatment efficacy. 

Blow dryers, flat irons, and other devices: Frequent use of a blow dryer tends to damage hair. The high heat from a blow dryer can boil the water in the hair shaft leaving the hair brittle and prone to breakage. Dermatologists recommend that you allow your hair to air dry. Then style your hair when it is dry. Dermatologists also recommend limiting the use of flat irons (these straighten hair by using high heat) and curling irons.
Protein: When the body does not get enough protein, it rations the protein it does get. One way the body can ration protein is to shut down hair growth. About 2 to 3 months after a person does not eat enough protein, you can see the hair loss. Eating more protein will stop the hair loss. Meats, eggs, and fish are good sources of protein. Vegetarians can get more protein by adding nuts, seeds, and beans to their diet.

Liver support: is necessary to eliminate unneeded wastes from the body. Everything we take in is processed through the liver and toxins are broken down into water soluble byproducts so they can be moved into the intestine and pulled into the stool for elimination. Foods like cruciferous vegetables (kale, broccoli, collard greens) and lemon support the liver detox pathways. Herbs like milk thistle, dandelion root, and burdock root help to support  liver cleansing.

It is perfectly normal for people to shed 50 to 100 hairs per day. This generally doesn't cause noticeable thinning of scalp hair because new hair is growing in at the same time that hair is shedding. However, hair loss occurs when this hair growth cycle and shedding is disrupted or when the hair follicle becomes destroyed and replaced with scar tissue. Female pattern hair loss (androgenetic alopecia) is the most common form of hair loss in women. This occurs gradually and is caused by genetics (from either side of the family), age, and the action of a specific male hormone, dihydrotestosterone (DHT). This hormone is found in lesser amounts in women and it preys on the hair follicles, preventing them from receiving vital nutrients for proper hair follicle growth, leading to the hairs shrinking, and resulting in a shorter lifespan. Interestingly, DHT does not need to be elevated to generate hair loss. Estrogen, when lowered as commonly seen in menopause, creates a change in the ratio of male to female hormones, giving an edge to these male hormones. Compounded with the sensitivity of DHT to the hair follicles, heredity can affect the age at which a woman begins to lose her hair, as well as the rate of hair loss and the extent of baldness. 


Surgeries, severe illnesses and emotional stress can cause hair loss. The body simply shuts down production of hair during periods of stress since it is not necessary for survival and instead devotes its energies toward repairing vital body structures. In many cases there is a three month delay between the actual event and the onset of hair loss. Furthermore, there may be another three month delay prior to the return of noticeable hair regrowth. This then means that the total hair loss and regrowth cycle can last 6 months or possibly longer when induced by physical or emotional stress. There are some health conditions which may go undetected that can contribute to hair loss. These include anemia or low blood count and thyroid abnormalities. Both of these conditions can be detected by a simple, inexpensive blood test.
