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.”
The study in question, which was first published in the journal PLOS Genetics earlier this year, analyzed the hair growth of 52,000 men between the ages of 40 and 69 in the UK. The numbers: 32% of the men said they did not experience any hair loss at all. 23% said they experienced a little bit. 27% had moderate hair loss, and the last 18% said they were suffering from severe hair loss.

Try out new hairstyles to disguise your thinning hair whilst you recover your hormonal balance. You may also want to consider a hair piece or clip-in extensions if your hair loss is very bad, but these should be used with care in order to prevent traction alopecia. You may also like to try using rollers or a hair volumizer, to add lift to your locks, or instantly hide thin patches with a good hair loss concealer.
Alopecia areata is a chronic autoimmune disease in which the immune system erroneously attacks the hair follicles, causing inflammation and temporary hair loss. Any hair-bearing skin site can be affected by alopecia areata, including the eyebrows. Treatment commonly involves corticosteroid injections into the site of eyebrow loss. Eyebrow hairs usually grow back, but may be a different color or texture than the lost hairs.
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. 

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.
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.
 Estrogen dominance is an extremely common imbalance and it can fuel thinning hair as well as an arms-length list of annoying symptoms, from bloating and PMS to irregular periods and infertility. Your first, best step in clearing excess estrogen from the body is doing a liver supportive detox. My 4-Day Hormone Detox has you eating fresh, nourishing foods for three meals a day, plus snacks. You won’t feel hungry or deprived and, most importantly, you will help kickstart hormonal healing. A hormone detox is one of the best first steps you can take to reverse thinning hair.
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]
Check for hypothyroidism. If you also notice unexplained weight gain, chronic fatigue, feeling depressed, or feeling colder than usual in low temperatures, your thyroid gland may not be producing enough hormones. You may also notice your periods getting heavier or becoming sporadic. Hypothyroidism is most common in women, especially over age 50, and it can be treated with a synthetic hormone.[31] 

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.


If, however, you aren’t so sure that any of the causes listed above are a problem for you, then a good place to start may be to talk with your healthcare provider about testing. It is important to learn the root cause – especially if dealing with infertility – because that which is causing hair thinning and shedding may also be contributing to your inability to conceive.
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.

Hormones are cyclical. Testosterone levels in some men drop by 10 percent each decade after thirty. 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 experiencing a long-term slowdown of hair loss (and a long-term increase in hair growth) while on a treatment that controls hair loss.
