With hirsutism, extra hair growth often arises from excess male hormones (androgens), primarily testosterone.
Androgens, such as testosterone (T), dihydrotestosterone (DHT), and their prohormones dehydroepiandrosterone sulfate (DHEAS) and androstenedione (A) are the key factors in the growth of terminal hair.
Estrogen is related to hair growth — and hair loss. During pregnancy, for example, a woman's estrogen levels are higher than normal, which signals more hair follicles to "grow" and fewer to "rest." While estrogen levels are high, women have full, thick hair.
Should you become pregnant in your thirties (or indeed, at any age), the rise in oestrogen and progesterone can make the hair gloriously luscious and thick, especially in the last few months of pregnancy. "Essentially, the increase keeps the hair in the anogen, or 'growth' phase for longer," explained Kingsley.
Both men and women can develop hormonal imbalances that can cause hair to thin or fall out. Often, treating the imbalance helps your hair regrow. Although most people think of estrogen or testosterone when they think of a hormone imbalance, issues with your thyroid can also lead to hair thinning.
When the levels of estrogen and progesterone drop, hair grows more slowly and becomes much thinner. A decrease in these hormones also triggers an increase in the production of androgens, or a group of male hormones. Androgens shrink hair follicles, resulting in hair loss on the head.
Hair loss can also be triggered by hormone changes that occur during menopause. During menopause women's estrogen and progesterone levels drop causing hair to grow more slowly and become thinner.
Progesterone also decreases the conversion of testosterone to dihydrotestosterone (DHT), the male hormone that directly makes dark, coarse facial hair grow. Two common things make increased facial hair and other androgen -related adverse effects: 1.
Too much estrogen can cause hair loss and thinning hair. Many times, an increase in estrogen is caused by perimenopause, ingesting or touching endocrine disruptor items and gaining weight. Estrogen affects the hormones, which in turn affect the ability for your hair to grow.
Lifestyle changes, such as a healthier diet, exercise, and stress reduction will also help you get your hormone levels back on track. Once equilibrium is restored to your hormones, hair loss associated with your hormone issue should slow or cease, and in many cases, hair that was loss may be replaced by new growth.
Lower estrogen and progesterone levels: Estrogen and progesterone stimulate hair growth, which is why pregnant women—who are producing extra levels of these hormones—tend to experience thickening hair during their pregnancy.
To get thicker hair, eat a healthy diet with omega-3 fatty acids, B vitamins, iron, and vitamin D. For thicker hair, it's important to use a sulfate-free shampoo and to stop using heat styling products like flat irons or curling irons.
This increase in DHT can potentially come from other things that affect hormonal balance, including menopause, stress, and/or underlying thyroid issues [3]. It's important to understand an important factor is genetic sensitivity to DHT.
It depends on your situation. Not all women need, want or are candidates for estrogen therapy. Estrogen can reduce menopausal symptoms like hot flashes, night sweats and vaginal dryness. If you have a uterus, you'll likely need to take progesterone along with the estrogen.
What happens if I have too much progesterone? There are no known serious medical consequences due to the body making too much progesterone. Levels of progesterone do increase naturally in pregnancy as mentioned above. High levels of progesterone are associated with the condition congenital adrenal hyperplasia.
If you don't have enough progesterone, you may have trouble getting or staying pregnant. After one of your ovaries releases an egg, your progesterone levels should rise. Progesterone helps the uterus thicken in anticipation of receiving a fertilized egg. If it's not thick enough, the egg won't implant.
Estrogen and progesterone levels fall, meaning that the effects of the androgens, male hormones, are increased. During and after menopause, hair might become finer (thinner) because hair follicles shrink. Hair grows more slowly and falls out more easily in these cases.
In both sexes, the specific hormone responsible for hair loss is the same: dihydrotestosterone (known as “DHT”), a hormone that your body produces as a byproduct of testosterone.

A Fred Hutchinson Cancer Research Center study involving postmenopausal, overweight, and obese women who took 2,000 IUs of vitamin D daily for a year found that those whose vitamin D blood levels increased the most had the greatest reductions in blood estrogens, which are a known risk factor for breast cancer.
Low estrogen levels can interfere with sexual development and sexual functions. They can also increase your risk for obesity, osteoporosis, and cardiovascular disease.
