Hormones are cyclical. Testosterone levels in some men drop by 10% each decade after age 30. Women's hormone levels decline as menopause approaches and drop sharply during menopause and beyond. The cyclic nature of both our hair and hormones is one reason hair loss can increase in the short term even when you are having a long-term slowdown of hair loss (and a long-term increase in hair growth) while on a treatment that controls hair loss.
I’m no Frida Kahlo, but since my teenage years, I’ve been blessed with thick, full eyebrows. But as soon as I turned 30, I noticed something was amiss. My beautiful brows were looking, let’s say, sparse. Every time my brow specialist handed me a magnified mirror after my monthly wax, it seemed I had more patchy spots. My low-maintenance morning routine—a quick brush-up and pencil fill-in—was suddenly taking up a lot more time. I found myself on a constant quest for the best brow powders, pencils, and gels, and started researching microblading in hopes of finding a solution.
There is also a different in the form of 5AR enzyme (5 alpha reductase) found on the facial hair follicles vs. the scalp hair follicles. This enzyme converts testosterone into that more problematic DHT. Type I DHT is found in sebaceous glands on the face and genital area whereas Type II is found in hair follicles of the scalp. Type II DHT is typically more of a problem in men, but Type II is increased in disorders with high testosterone like PCOS.
Most of us look at the eyebrows as a patch of hair that has an aesthetic purpose and it is often shaped for cosmetic purposes. Although the exact purpose of the eyebrows is not conclusively understood, it is believed to be prevent water or sweat from falling on to the eyes itself. For most people its function is of little concern compared to its cosmetic purpose. As with hair anywhere on the body, eyebrow hair and the follicles from where it arises can be prone to the same diseases and disorders which may lead to hair loss..
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).
These are only a few of the common myths heard by physicians and other hair loss specialists on a daily basis. The American Hair Loss Council suggests that you first have your hair loss diagnosed by a competent dermatologist who sees hair loss patients on a regular basis. Once you know the diagnosis you will have a better understanding of exactly which treatment option may be best for you.

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.
Eyebrow loss, also known as superciliary madarosis, can occur with a variety of medical conditions. Madarosis can affect one or both eyebrows with partial or complete hair loss. Infections, chronic skin disorders, hormone disturbances, autoimmune diseases and medications are among the many medical reasons for eyebrow loss. In most cases, identification and treatment of the underlying condition leads to regrowth of the eyebrows. Permanent eyebrow loss can occur with disorders that permanently damage the hair follicles.
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.

Contrary to popular belief, hair does not grow continuously but actually grows in cycles. It starts at the follicles which are embedded in the skin and the visible part, the shaft, is a consequence of active growth at the follicles over time. The living part of the hair in the skin has blood and nerve supply while the hair shaft is made up of dead cells and protein and does not have a blood or nerve supply. Therefore it can be easily cut without any bleeding or pain.

Insulin regulation is also a big factor in hair health, as an imbalance can lead to various hormonal effects. Insulin helps to regulate blood sugar levels, which effects fat storage and hormone balance. Fat storage and hormone balance play a role in hair growth because fat storages will secrete excess estrogen in the body, and can desensitize hormone signals.  


Accurate placement of the grafts is necessary to ensure a good cosmetic result. In the medial third, the needles should be inserted parallel to the brow axis.[203] The follicles should point toward the tip of the nose and the hairs should converge toward each other in the other two segments, that is, the bulbs in the upper part point toward the forehead and in the lower part toward the other eyebrow.[204]

Madarosis of non-scarring type is commonly seen in alopecia areata which is a hair-specific autoimmune disease associated with patchy loss of hair.[56] It presents as round or oval patches of non-scarring hair loss. Madarosis occurs as isolated involvement [Figure 2] or as a part of alopecia universalis.[57] When alopecia areata involves the eyelashes exclusively, there is rarely involvement of other parts of the body.[58] Alopecia areata can involve both the eyelids without scalp involvement also.[59] Short exclamation mark hairs are pathognomonic for alopecia areata.
Estrogen and combined oral contraceptive (COC) drugs with estrogen or progestogen have been reported as effective, but data are limited (Adenuga et al., 2012, Raudrant and Rabe, 2003, Scheinfeld, 2008). They are thought to function through several mechanisms. Both components of COC drugs increase the levels of sex-hormone-binding globulin (Schindler, 2013). They also send negative feedback signals that suppress the hypothalamic secretion of gonadotropin and releases the hormone and pituitary secretion of the luteinizing and follicle-stimulating hormones, which results in a decreased androgen production (Gilman et al., 1990, Varothai and Bergfeld, 2014). These actions decrease androgen secretion from the ovary and the quantity of free, biologically active androgens, which reduces their effects on the hair follicles (Schindler, 2013). Our practice when prescribing COC drugs is a combination of ethinyl estradiol 20 mcg plus drospirenone 3 mg. Drospirenone is an analogue of spironolactone. This treatment combination is approved by the FDA for the treatment of acne but not alopecia.
A decline of estrogen, whether due to menopause or other hormonal imbalances, can also affect hair growth. You'll experience a thinning or loss of pubic hair as well as hair on your scalp if you have low levels of estrogen in your body. You might also experience unwanted hair growth on your face during menopause, when your estrogen levels are at their lowest. This phenomenon occurs because the lack of estrogen leaves you with a hormonal imbalance of sorts; you have more androgens, or male hormones, than female hormones in your body, which contributes to some male-like symptoms such as body and facial hair.
There are numerous diseases that can affect the hair and scalp. Hair loss can be caused by a variety of conditions. Diseases such as alopecia areata, anemia, male/female pattern baldness, and infections of the scalp can all cause significant difficulty and loss of daily well-being. Stanford Dermatology has established a special clinic focusing on the diagnosis and treatment of these disorders of the hair.

Take extra care in looking after your hair. Use a gentle, nourishing shampoo (we love Bumble and Bumble Gentle Shampoo) to promote good condition and prevent breakage. Try using a silk or satin pillowcase. Avoid harsh styling products and techniques that apply heat to the hair (blow drying, curling irons etc) as these can cause more damage to fragile hair.

Medicines may also help slow or prevent the development of common baldness. One medicine, minoxidil (brand name: Rogaine), is available without a prescription. It is applied to the scalp. Both men and women can use it. Another medicine, finasteride (brand name: Propecia) is available with a prescription. It comes in pills and is only for men. It may take up to 6 months before you can tell if one of these medicines is working. 

Furthermore, Penn dermatopathologists developed an even more advanced method called the HoVert technique for diagnosing hair loss and other disorders from a scalp biopsy. The technique uses a unique horizontal and vertical testing approach that provides a greater amount of information to the referring dermatologist than standard industry longitudinal scalp biopsies.

Some medications have side effects that include hair loss. Talk to your doctor if you are experiencing significant hair loss and you think that your medication might be the cause. Your doctor might be able to switch you over to another type of medicine without any reported side effects. Don’t stop taking your medications until you’ve spoken with your doctor, as this could be dangerous for your health.


When men have hereditary hair loss, they often get a receding hairline. Many men see bald patches, especially on the top of the head. Women, on the other hand, tend to keep their hairline. They see noticeably thinning hair. The first sign of hair loss for many women is a widening part. In rare cases, men see noticeably thinning hair. And in rare cases, women can see a receding hairline or bald patches. The reasons for this are unknown.
Posterior blepharitis is characterized by either excessive foam in the tear film in the hypersecretory type, or plugging of the meibomian orifices in the obstructive type. Expression of the secretions reveals a turbid or toothpaste-like material.[32] If there is spillover inflammation of the anterior lid margin, there may be a loss of eyelashes.[33]
See a dermatologist for itchy skin or rashes around your brows. These patches may indicate a skin infection or interaction with a new beauty product or environmental trigger. You could also have inflammation from dermatitis or psoriasis.[32] These conditions don’t actually cause hair loss, but they can lead to it if you rub and scratch the affected areas.
Thank goodness! I am a teacher which requires me to get up about 5:30 during the school year. This summer, I will turn 62 and although I’ve always had problems waking up early in the morning – he it is so severe that I am sleeping 12 to 14 hours a day! This is terrifying as school starts in less than two weeks. I am postmenopausal for close to 20 years now and recently found out that my estrogen level is elevated. Your article is a godsend; I will now be able to have an intelligent discussion with my gynecologist and hopefully become a morning person for the first time in my adult life!
Madarosis is a terminology that refers to loss of eyebrows or eyelashes. This clinical sign occurs in various diseases ranging from local dermatological disorders to complex systemic diseases. Madarosis can be scarring or non-scarring depending upon the etiology. Appropriate diagnosis is essential for management. Follicular unit transplantation has been found to be a useful method of treating scarring madarosis and the procedure relevant to eyebrow and eyelash reconstruction has been discussed. A useful clinical approach to madarosis has also been included for bedside diagnosis. The literature search was conducted with Pubmed, Medline, and Google scholar using the keywords madarosis, eyebrow loss, and eyelash loss for articles from 1960 to September 2011. Relevant material was also searched in textbooks and used wherever appropriate.
Mistakenly thought to be an exclusively male disease, women make up a significant percentage of hair loss sufferers all around the world. Forty percent of women have visible hair loss by the time they are age 40. After menopause, that number increases even more. Hair loss in women can be absolutely devastating for self-confidence, self-image and emotional well-being. Although it is not a life threatening disease and sometimes underestimated by physicians, hair loss can take an emotional toll that directly affects physical health. Hair is an important part of woman’s face and beauty, therefore it is not easy for any woman to face changes that affect the quality and especially the quantity of her hair. Hair loss in women is a serious life-altering condition that shouldn’t be ignored and has to be diagnosed and treated in the best possible way.
This is an autoimmune disorder that is also known as “spot baldness” and can result in hair loss ranging from just one location (alopecia areata monolocularis) to the entire scalp (alopecia totalis), or to every hair on the entire body (Alopecia areata universalis). Although it is thought to be caused by hair follicles becoming dormant, what triggers alopecia areata is not exactly known. In most cases, the condition corrects itself.

Estrogen is the dominant female sex hormone which is essential for the development of female characteristics. It can however be also found in men as well, but in lower quantities. Likewise there are also few quantities of the male sex hormones Testosterone, in female body. Estrogen is not a single hormone but actually a group of female sex hormones which include estradiol, estriol and estrone hormones. Estrogen is made in the ovaries and to a lesser extent in other bodily tissues.

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.


Toxic alopecia occurs when there is a disruption of hair growth in the anagen phase. This usually occurs following chemotherapy and radiotherapy.[94] Radiotherapy for various types of ocular tumors, eyelid and choroidal tumors have been reported to produce madarosis.[95–97] Hair loss due to radiation is usually reversible, but may be permanent when the dose of radiation is in the range of 50 to 60 Gy.[94]
The recipient sites in the eyebrow can be conveniently made with 20 to 22-gauge needles parallel to the skin, so that hair grows flat on the skin and does not stick out from the face. About 150 hairs are required for a full eyebrow graft. Poddar et al. described good results with a technique of creating recipient tracks with the erbium yttrium aluminium garnet laser.[202]
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. 

There is pilosebaceous inflammation[45] with both scarring and non-scarring alopecia depending on the degree of inflammation. Most commonly, there is involvement of the head and neck, though widespread involvement is also seen. Eyebrow loss is a prominent finding and may be the presenting symptom when the eyebrow region is involved in the acute benign form of follicular mucinosis.[46]
A small study published in 2002 found that applying topical onion juice to the scalp increased hair growth. Two groups of participants were asked to use topical treatments on their scalps twice each day for two months: one group was given onion juice to apply to their scalp. The other was given tap water. After six weeks, hair growth was observed in close to 90 percent of the participants who used onion juice (though the researchers noted that more men in the group than women experienced hair growth). In the tap water group, only 13 percent of the participants experienced hair growth (with no difference between the sexes.) The benefit from onion juice is thought to come from its high sulfur content. Sulfur is found in amino acids, which are the building blocks of proteins, which are needed for robust hair growth. Onion juice may also stimulate collagen production, which in turn stimulates hair growth.
Topic prostaglandin analogues are used for the treatment of glaucoma. Uniocular increase in length, thickness, and pigmentation of the lashes were described by Johnstone in 1997 by patients using latanoprost in one eye.[184] There are reports of a response of alopecia of eyelashes to cutaneously administered latanoprost,[185,186] though others report limited success.[187] Eyelash growth has also been reported following bimatoprost 0.03% topically to the base of the eyelashes in healthy individuals[188–190] and in individuals with alopecia areata.[191] Bimatoprost ophthalmic solution 0.03% is the only Food and drug administration (FDA)-approved product to safely and effectively enhance the growth of a patient's own eyelashes.[192,193]
Seborrheic dermatitis is a condition where you have itchiness in the eyebrows.. like serious, serious itchiness. First of all, if you think you have this: see a derm, stat. You need a derm to confirm (can I trademark that saying?), and you definitely need a derm for the prescription. A dermatologist will tell you to treat the seborrheic dermatitis with a combination of desonide cream and ketoconazole cream twice daily for one week. Or, they may tell you to use a ketoconazole shampoo to control the problem.
When you choose dōTERRA®, you are choosing essential oils gently and carefully distilled from plants that have been patiently harvested at the perfect moment by experienced growers from around the world for ideal extract composition and efficacy. Each dōTERRA essential oil is also carefully and thoroughly tested using the strict CPTG Certified Pure Therapeutic Grade® quality protocol.

Another reason why hair falls out is lupus. Lupus is an autoimmune disease that may make your immunity system begin attacking your various healthy body tissues. According to Medical News Today, “this results in symptoms such as inflammation, swelling, and damage to joints, skin, kidneys, blood, the heart, and lungs”. It can also attack eyebrow follicle resulting sudden hair loss and including brows.
“When I went in for my Bosley consultation, my senior counselor was the one who walked me through the procedure. He also had had the procedure done, and his results were phenomenal. And I was thinking, ‘Wow, if I can get that, that’s what I’m looking for.’ He really got it — he understood me. He understood what I went through, and that was really important to me.
Dozens of other causes of eyebrow loss are also possible including a variety of infectious, autoimmune and inflammatory conditions. Consultation with a dermatologist or hair transplant surgeon is recommended. I strongly advise consulting a dermatologist before proceeding to hair transplantation for women over 40 with new onset eyebrow hair loss after age 40.

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.

Other important vitamins for eyebrow hair growth to consider include vitamin B complex especially vitamin B-12, B-7 (biotin), can ensure healthy hair and skin. In addition, vitamin D can help in hair growth by creating new pore and thus a possibility of more hair (see more on Stem Cells Translational Medicine. Finally ensure you have zinc, enough protein, and omega 3 fatty acids.

Prevention is better than cure, so they. Can you really prevent or stop losing your brows? Is there a way to prevent eyebrow hair loss? Depending on the cause, it is possible to prevent them. You need to stop the causative reason. For instance, if you have been over plucking, tweezing or threading, you need to stop it until your eyebrows have grown again. If your eyebrow loss is caused by some medications you are using, whenever possible, stop using them. However, if you are attending chemotherapy session for instance, it is not practical to stop your sessions as a ways of preventing this loss.


Reproductive hormone changes can also play a part, and dermatologists believe the same factors that cause hair loss from the scalp, a common problem for women as they age, may contribute to thinning brows. Nanette Santoro, M.D., ob/gyn and professor of reproductive endocrinology at the University of Colorado at Denver, says, “Abrupt hormone changes can cause sudden hair loss (telogen effluvium) that recovers over about six months' time. It happens postpartum to many women and can happen at menopause.”
Estrogen describes a number of female sex hormones primarily made in the ovaries. Estrogen responsible for your female physical traits and characteristics, having the opposite role of the male hormone testosterone. Although men do have some estrogen and women have some testosterone, for the most part, the primary hormone’s levels block out the effects of the opposite sex hormones.
