In your first 6-12 months on estrogen, people on estrogen may notice changes in their body hair, facial hair, and even scalp hair. While the full effect of hair growth changes may take up to three years to develop, they are a natural part of transitioning with estrogen.
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.
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.
While estrogen can help thin hair, it cannot completely reverse facial and body hair growth.
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.
HRT and Hair Regrowth
Estrogen and progesterone are hormones that aid in healthy hair growth, so when your body stops producing these, it can cause hair loss. Taking HRT can help prevent this loss and may even help regrow hair. In fact, some trans women with androgen alopecia who underwent HRT saw hair regrowth3.
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.
The female sex hormone oestrogen makes body hair fine and soft. Androgens are male sex hormones, including testosterone, which are responsible for masculine characteristics such as facial hair and coarse body hair. A woman's ovaries and adrenal glands naturally make a small amount of androgens.
According to Harvard Health Publishing, topical minoxidil is the most common treatment for androgenic alopecia or hormonal hair loss as opposed to corticosteroids for non-hormonal hair loss treatment. Corticosteroids reduce inflammation and lower the immune response in alopecia areata.
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.
Estrogen probably prolongs the growth phase of hair. There are estrogen receptors on our hair follicles. With menopause, estrogen levels from our ovaries decrease and testosterone is predominant. Testosterone shortens hair growth phase making hair thinner and slow to growth.
Estrogen can ease vaginal symptoms of menopause, such as dryness, itching, burning and discomfort with intercourse. Need to prevent bone loss or fractures. Systemic estrogen helps protect against the bone-thinning disease called osteoporosis.
It may take a few weeks to feel the effects of treatment and there may be some side effects at first. A GP will usually recommend trying treatment for 3 months to see if it helps. If it does not, they may suggest changing your dose, or changing the type of HRT you're taking.
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.
B Vitamins
Because B vitamins play a vital role in the creation of estrogen, low levels of B vitamins can result in reduced production of estrogen. Vitamins B2 and B6, in particular, are associated with healthy estrogen levels.
Irregular periods, hot flashes, difficulty sleeping, mood swings, and headaches can all be signs of low levels of the hormone estrogen in women. The most common cause of low estrogen is perimenopause, your body's transition into menopause, but other factors can be involved.
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.
Estrogen affects the hypothalamus, which regulates body temperature. Low estrogen causes hot flashes and night sweats, two annoying symptoms of menopause and perimenopause.
Hormone Replacement Therapy (HRT) restores your body's oestrogen to an average pre-menopausal level. This treatment relieves menopausal symptoms, including hot flashes, mood swings, osteoporosis and decreased libido. It is also known to help with hair thinning.
Hormone replacement therapy (HRT) can affect weight loss in women. In addition to having less abdominal fat, the same study found that women undergoing HRT were almost one whole point lower on the body mass index (BMI) scale, and they had nearly 3 pounds less of fat mass.
The appearance of menopausal hair loss can sometimes be improved by cosmetic practices, e.g. reducing the use of straighteners, hair dryers and other heat damaging tools. This along with the use of thickening shampoos and conditioners may improve hair appearance.
