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.
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.

Yeah right! The way Policing works in this country now if you stopped someone giving a cop a good hiding the same cop would then nick you for assaulting his attacker. NO CHANCE! The police got themselves into this by not doing their jobs properly and PROTECTING innocent people. Now? What trust and support there ever was for them is almost gone.....by their own hand.

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]
Androstenedione, which is mostly produced in the ovary and adrenal glands, is converted to testosterone by 17β-hydroxysteroid dehydrogenase. Testosterone then circulates throughout the body to reach its target tissues. Androgen-metabolizing enzymes have been found in many parts of the hair follicle (Table 1; Bolognia et al., 2012). The presence of those enzymes makes the pilosebaceous unit a site of androgen metabolism and synthesis (Fazekas and Sandor, 1973). Circulating free testosterone either binds to intracellular androgen receptors in the hair bulb and dermal papilla, which facilitates miniaturization of the follicle, or is metabolized into dihydrotestosterone (DHT) by the enzyme 5-alpha-reductase. DHT then binds the same receptor but with much greater affinity (Kaufman, 2002, Levy and Emer, 2013). Of the androgens depicted in Figure 1, only DHT and testosterone bind to androgen receptors (Burger, 2002).
See the doctor for sudden hair loss. If you suddenly lose your eyebrows, that could be a sign of a more serious problem, particularly if you only lose your eyebrows or eyelashes and not other hair. Sudden loss of eyebrows can be a symptom of eye conditions, skin conditions, systematic disorders, infections, and nutritional deficiencies. Seeing your doctor can help you narrow down the condition.[30]

There’s no doubt that estrogen and hair loss are connected, but there are certain factors that determine how much of an effect estrogen levels have on your hair. As one of the main visible measures of your health, hair growth is often one of the first areas affected when hormones are off-balance. Let’s take a look at the links between estrogen hormonal imbalance and hair loss.

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!

Insulin, that helper hormone in charge of regulating blood sugar levels, also affects a number of different body processes, including fat storage, heart health and, you guessed it, hair growth. One study published in the European Journal of Cardiovascular Risk found that women with some markers of insulin resistance have a greater risk for androgenic alopecia (AGA), or female pattern baldness.

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]
It is known that during pregnancy, because of an increased level of estrogen, there is a tremendous growth of new hair. However, during menopause it is noticeable that the reduced level of estrogen hormone tends to cause hair loss. When the estrogen hormone levels tend to drop, the hair follicles fall under the influence of the male sex hormone or the testosterone, which cause the shortening of the growth phase of hair. Subsequently there is a noticeable hair loss. This hair loss caused due to the drop down of estrogen levels may cause patchy hair loss or complete baldness.
Hansen's disease, also known as leprosy, is an infection of the skin and nerves caused by the bacterium Mycobacterium leprae. The disease often affects the skin of the eyebrow region, leading to loss of sensation and permanent loss of the eyebrow hairs. There are numerous other rare and uncommon causes of eyebrow hair loss, including vitamin A toxicity, nutritional disorders and other dermatological disorders. If you experience loss of eyebrow hair, see your doctor to evaluate the cause and to discuss a treatment plan.
According to the International Society of Hair Restoration Surgery, since 2004, the number of female surgical hair restoration patients worldwide increased 24 percent. Modern surgical hair restoration procedures such as Follicular Unit Transplantation (FUT) and Follicular Unit Extraction (FUE) allow surgeons to take hair from the back of the head (genetically permanent hair zone) and transplant it to the areas where balding has occurred. The reason why the hair does not fall out once transplanted in its new location is because those hair follicles take on the same characteristics as the hair in the area where it originated, the genetically permanent zone. Both approaches result in lasting outcomes. In order to know if you are a candidate, Dr. Yaker will go over your medical history and examine your hair and scalp. He will determine if you have ample, good quality hair in the permanent hair zone in order to be able to relocate those hair follicles to the areas of hair loss.
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.
The first thing you'd want to try is to talk to your doctor about stopping the medicine -- ask if there's a substitute. If you can't find a substitute for the medication and you must take it, then you could consider filling in your eyebrows. You can find brow products at any local drugstore. YouTube has many, MANY brow tutorials you could learn from.
Sinclair Scale: The 5-point Sinclair Scale is a modified visual grading scale. Grade 1 is normal. This pattern is found in all girls prior to puberty, but in only half of women age 80 or over. Grade 2 shows a widening of the central part. Grade 3 shows a widening of the central part and thinning of the hair on either side of the central part. Grade 4 reveals the emergence of diffuse hair loss over the top of the scalp. Grade 5 indicates advanced hair loss. This grade is uncommon, occurring in less than 1% of women.
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.

Over Plucking: I know the temptation of tweezing your eyebrows when you don’t want to endure the pain of threading. But when you pluck your eyebrow hair, you’re pulling it out from the follicle and essentially damaging it. And repeatedly plucking your hair eyebrow hair can permanently damage your follicles over time and prevent them from producing new hair.
Also new is the HairMax Laser Comb. It's a red light therapy hairbrush-like device that increases circulation and the biological march that makes hair. It's only approved in men (though some women are using it) and in my experience, is not as good as minoxidil. But in one study, 45% of users reported improvement after eight weeks, and 90% saw improvement after 16 weeks.
It is known that estrogen plays a great role in reducing bodily hair, in promoting the growth of the hair on your head, controlling height, reducing the muscle mass, promoting the breast growth, keeping the skin smooth, keeping away from wrinkles, regulating menstrual cycle in women, preventing fatigue, keeping away depression etc. From all these it can be known that estrogen hormone is important for the overall health of an individual.

In extreme cases, such as disordered eating and anemia, an iron deficiency may be to blame for thinning brows. “Even if you don’t have anemia, and you have low levels of stored iron, that could contribute to hair loss,” says Rajani Katta, M.D., a dermatologist and clinical assistant professor of medicine at Baylor College of Medicine, who studies the link between nutrition and hair loss. Iron is found in meat, fish, and other animal products, plus beans and legumes, so vegans and vegetarians might be more likely to be low in iron. Your derm can do a ferritin blood test to check your iron levels. But don’t start an iron supplement without medical recommendation. Too much iron can also have negative effects, says Dr. Katta.
You can even increase your own natural hair growth by eating the right food. Since hair growth depends on what happens inside of your body, it only makes sense that what you eat matters. Foods high in protein are really good for preventing hair loss, since protein is what makes up the hair. Eggs, fatty fish, beef, pork tenderloin, chicken and lentils are all good. Another general rule is to eat many greens and veggies. Kale, spinach, bell peppers, carrots and onion all promote healthy hair growth. Basically, you need to make sure you get all the vitamins and minerals that the body needs to keep producing hair. If you find it hard to get all the important nutrients daily, you can supplement your daily diet with a specialized hair supplement.
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.
Another cause of eyebrow hair loss is genetic predisposition. Many patients naturally have thinner eyebrows that run in their family. This is one of the biggest reasons patients seek our services. Medical conditions such as hypothyroidism, eczema, and alopecia areata (spot baldness) can also lead to brow hair falling out. It’s important to determine the cause of your condition to find an effective treatment.
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.

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.

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]
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.”
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.
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.
Scurf refers to the scales and greasy crusts that accumulate along the hair shaft and indicates the presence of seborrhea.[26,27] Collarettes are composed of hard fibrinous scales[25,28] surrounding each individual eyelash. They travel upward along with the growth of the lashes and are indicative of staphylococcal infection. Sleeves or cylindrical dandruff comprise scales that form a cuff around the lash root and are connected with it, in contrast to greasy scales which are not connected to the lash root.[29] Sleeves indicate infestation with Demodex folliculorum.

Thyroid hormone receptors were detected in both dermal and epithelial compartments of the human pilosebaceous unit.[48] T4 and T3 decrease the apoptosis of hair follicles and T4 prolongs the duration of anagen in vitro.[49] Thyroidectomy delays initiation of anagen. Administration of thyroxine advances anagen, initiation of which is however delayed once toxic doses are given. Therefore, ratio of telogen to anagen hairs is increased in hypothyroidism as well as hyperthyroidism.[50] Thus, the hair follicles are affected in thyroid disorders, and madarosis is caused due to disturbances in hair cell kinetics. Hypothyroidism is associated with generalized hair loss probably due to coarse, dull, and brittle hair with reduced diameter.[51] The eyebrows and eyelashes may also be lost. Loss of lateral one-third of eyebrows known as Hertoghe sign[38] is a characteristic sign of hypothyroidism.[52] Some people also refer to it as Queen Anne's sign,[53] after Anne of Denmark whose portrait with shortened eyebrows has been interpreted by some as indicative of the presence of goiter, even though such a fact has not been proved by any known sources of information. Madarosis may even be the presenting sign in hyperthyroidism.[21] In hyperthyroidism, there is thinning with breaking off and shortening of hair.[54] Madarosis can also occur in hypopituitarism, hypoparathyroidism,[21] and hyperparathyroidism.[55]
