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.
Estrogen and progesterone can help keep your hair in the growing (anagen) phase. Therefore, these hormones can help your hair stay on your head longer and may even help your hair grow faster. This may be why many women notice their hair thinning starts to improve with estrogen replacement therapy.
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.
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.
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.
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.
Effects of Hormone Replacement Therapy on Hair Loss
While trans women who were suffering from androgenetic alopecia prior to starting HRT may see a reversal of their hair loss, the results have not been universal. More interestingly, blocking DHT in men tends to only slow hair loss.
By supplementing your body's natural hormone levels, HRT can help you maintain a more youthful body composition. While this effect is particularly evident in men, research suggests that women can also benefit. HRT is also known to help women maintain softer, smoother skin, resulting in a younger look.
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.
Hairstyling and scalp massage
using a gentle shampoo that does not remove moisture. using a moisturizing conditioner to reduce breakage and split ends. applying a leave-in conditioner after washing and conditioning to prevent frizz and breakage. wrapping the hair in a microfiber towel before blow-drying it.
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.
Hair follicles come in different shapes and sizes, affecting hair texture and width. Some people have wider follicles-and therefore, thicker hair strands-than other people. Genetics influence hair thickness, but other factors like hormones and age are important factors, too.
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.
With that said, one of the physical changes that accompany estrogen hormone replacement therapy is body and facial hair thinning. Those on estrogen GAHT (both estradiol and anti-androgens and/or progesterone) can experience hair thinning on the face, chest, abdomen, legs, and arms.
Conclusions: Hormone treatment in transwomen induces an increase in cheek tissue and a decrease in jaw tissue. In transmen a tendency of decrease in cheek tissue and an increase in jaw tissue was found. These changes are in the direction of the desired gender. Tebbens M, Nota NM, Liberton NPTJ, et al.
Hormone replacement therapy (HRT) has been shown to increase epidermal hydration, skin elasticity, skin thickness (Sator et al 2001), and also reduces skin wrinkles (Phillips et al 2001).
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.
Certain HRT products can help to treat female pattern hair loss. The hair- friendly ones are Premique and Indivina (both of these products contain the anti- androgen medroxyprogesterone acetate) and Angeliq (containing drospirenone).
It's important to understand that this is not a quick-fix for hair loss in women. The drug must be used for at least two consecutive months to notice a difference, and the effect is usually noticed around the four-month mark, but it could possibly take longer. A six to 12-month trial is recommended.
Menopausal hair loss is directly related to the decreased production of estrogen and progesterone. As these hormone levels drop, hair may begin to grow more slowly and become thinner.
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.
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.
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.
