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.
Hair loss is something that everyone experiences sooner or later, but some get it earlier than others. Losing hair prematurely can be traumatic. Because of that, there is an infinite number of products that claim to cure and reverse the problem. But what if you could find out the likelihood that you will experience hair loss so that you could prevent it before the symptoms even showed? Researchers in the United Kingdom have reportedly found a way to predict who is at risk.
“…a beauty editor told me she had been using Viviscal... Since beauty editors see truckloads of products every week, I was immediately convinced when she said it worked – so I bought it myself. I started taking it twice a day for the first six months and saw dramatic results within three to four months. My hair was less thinned out …and it was also less brittle. I’ve gone to the same hairdresser since I was 19, and he was the first to comment on how full and strong my hair looked…”

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.

For now, therapies include cortisone injections directly into the bald patches; topical cortisone; Minoxidil — known to many people under the brand name Rogaine; and anthralin cream. A less-widely available option is topical immunotherapy: certain chemicals applied to the scalp can trigger an allergic rash, which alters the immune response, NAAF notes.

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.
However, the effects of alopecia reach far beyond symptoms of depression and include anxiety, obsessions, dissatisfaction with one’s appearance, and low self-esteem (Al-Mutairi and Eldin, 2011, Dlova et al., 2016, Hunt and McHale, 2005, Schmidt et al., 2001). There can be significant disturbance in a patient’s social life because they may change their hair style, clothing, or avoid social meetings (Al-Mutairi and Eldin, 2011). One study reported that 40% of surveyed women described marital problems and 63% had career-related issues that they ascribed to their hair loss (Hunt and McHale, 2005). These effects seem to occur regardless of patients’ age, race, or degree of hair loss (Dlova et al., 2016, Hunt and McHale, 2005, Schmidt et al., 2001). Another study of more than 200 women found that this psychologic morbidity occurs with equal frequency in women whose hair is typically covered by a headscarf (Erol et al., 2012).
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.
The hormone imbalance known as hypothyroidism is a common cause of abnormal eyebrow thinning, especially in women; roughly 27 million Americans suffer from thyroid disease, and about 80 percent of them are women. Thinning eyebrows appear as a symptom of both hypothyroidism (underactive thyroid production) and hyperthyroidism (overactive thyroid production), alongside issues such as excessive fatigue, difficulty losing weight and constantly feeling cold. If your brows appear particularly thin around the edges, visit your doctor for a thyroid screening, which should include thorough blood work. With prescription medication, your eyebrows should fill back in over the ensuing months.
Hypoproteinemia[71] causes loss of hair due to premature onset of telogen. Loss of eyebrow hair has been reported due to chronic zinc deficiency in a patient receiving only parenteral nutrition for 2 months.[26] Acrodermatitis enteropathica is an inherited disorder of zinc deficiency which shows loss of eyebrows and lashes in addition to cutaneous manifestations.[72,73] Biotin deficiency can result in encephalopathy, neurological disorders, skin desquamation, and loss of eyebrows and eyelashes.[74] Iron deficiency may be a possible cause for diffuse telogen hair loss; its exact role however is subject to speculation.[75]

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.

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.


Some cancer chemotherapy drugs cause temporary hair loss, which affects all body hair. Along with the loss of scalp hair, people undergoing chemotherapy also commonly lose their eyebrows and eyelashes. Chemotherapy drugs that frequently cause hair loss include paclitaxel, 5-fluorouracil, carboplatin, cisplatin, actinomycin-D, bleomycin, vincristine, cyclophosphamide, altretamine, etoposide, docetaxel and doxorubicin. Hair loss typically begins 2 to 3 weeks after the start of chemotherapy. Lost eyebrow hair regrows in the weeks to months following completion of treatment.

Telogen effluvium is the second most common type of hair loss. It is predominantly seen in women between the ages of 40-70, but may occur at any age. Its symptoms include excessive thinning, shedding, and balding and it may happen abruptly. Common causes of sudden hair loss include changes in hormone levels such as with child birth, menopause, poor nutrition, medical conditions such as iron deficiency anemia and hypothyroidism, medications, severe illness or infection, major surgery, and even extreme levels of stress.
Giorgos Tsetis: In the beginning, we left three factories because we didn't feel confident that they could do the job at our standard. These type of factories are sourcing the ingredients for you, but you have no clue where these ingredients are coming from. You don't know the efficacy, if they're clinically tested, and what about absorption? As a company, we decided to identify these root triggers that play a role in disrupting the hair growth cycle, then rigorously tested how we can target them and what specific ingredients solve for each trigger. Then, we developed individual partnerships with top suppliers all over the world that specialized in single ingredients that actually have that efficacy. We decided to source our own ingredients because we wanted to control the entire process. At least nine of the ten companies we consulted with said we couldn't do that, because the ingredients we chose to use were incredibly expensive. That's one main reason others can't do the work we do. For example, we purchase our primary ingredient for $600 per kilo, and you can buy the standard version of that ingredient in China for $30 per kilo. Same ingredients, but ours is clinically tested and proven to be effective. We only use patented ingredients, which made others think we're crazy, but creating the absolute best product is our top priority.
Modern medical studies and research have not found any cure or possible medication for Alopecia. However, there are various treatments available for hair growth, or at least temporarily. It is recommended to consult a medical expert or dermatologists to gain more knowledge regarding the condition before undergoing through treatment and medications. Listed are treatments and products under cosmetic dermatology and general dermatology which could help you with your skin concern.
The real culprit appears to be dihydrotestosterone (DHT), a more potent form of testosterone. DHT is made from testosterone by a specific enzyme in the body, and while both testosterone and DHT are known to have a weakening effect on hair follicles, there appears to be something unique about the conversion process of testosterone to DHT that relates to thinning hair. This is why some drugs that are marketed for hair loss block the conversion of testosterone to DHT. (It’s important to note, however, that these drugs tend to be less effective in women than men, and that one of them—finasteride—is only approved for hormonal hair loss in men, not women. What’s more, the drug has been associated with increased risk of sexual side effects, depression, nausea, hot flashes, and increased estrogen levels—and too much estrogen is its own risk factor for thinning hair; more on that below.)

Unfortunately, there’s no magic solution, pill or product that will correct hair loss entirely. But if you think of your hormones as a cast of characters, knowing which ones are leading the show and which ones are only playing a supporting role can help you get to the bottom of the issue. If you haven’t already, take my free hormone quiz – it can help you determine what tests you may want to request from your doctor and which lifestyle or dietary changes may benefit you most. In the meantime, manage your stress levels and get enough sleep. This will help with general hormone balance and can protect your precious locks from any further damage.
