Brain hormones significantly affect hair color and could potentially be used to prevent or reverse grey hair.

Amenorrhea is when a woman doesn't have periods, with primary amenorrhea starting by age 15 or within five years of breast development, and secondary amenorrhea when periods stop for three months. It affects 3-4% of women not pregnant, breastfeeding, or in menopause, mainly due to polycystic ovary syndrome, hypothalamic amenorrhea, hyperprolactinemia, and ovarian failure.

Researchers found genes that control hair color and growth change before the visible coat color changes in snowshoe hares.

Low prolactin in young women may increase heart and metabolism risks.

The spiny mouse is a unique menstruating rodent that can help us understand menstruation and reproductive disorders.

Changing light exposure can affect hair growth timing in goats, possibly due to a key gene, CSDC2.

The study found that women with hyperandrogenic PCOS have higher levels of AKT1 and AKT2 proteins in their cells, which may lead to cell dysfunction.

FPHL causes hair loss in women due to genetics and hormones; minoxidil and anti-androgens are treatments, and early intervention is advised.

Amenorrhea, or the absence of periods, should be evaluated by age 15 or within five years of early breast development, and is most commonly caused by conditions like polycystic ovary syndrome and hypothalamic amenorrhea.

Moderately high prolactin levels do not cause hair loss in women.

Angora goat hair grows faster and produces more protein than cashmere goat hair, and certain hormones and nutrients positively affect hair growth and protein synthesis.

Certain drugs, especially antiandrogens and spironolactone, significantly increase the risk of gynecomastia.

Women with androgenetic alopecia (hair loss) have normal prostate specific antigen levels but higher testosterone levels.

Finasteride and minoxidil are effective for hair regrowth, while treatments for alopecia areata have varying success and continuous treatment is necessary.

Hormones like estrogen, testosterone, progesterone, and prolactin play complex roles in female sexual function, with testosterone potentially improving sexual desire, arousal, and satisfaction. However, more research is needed to establish safe and effective hormone treatments for female sexual dysfunction.

Melatonin protects skin against UV damage by regulating various cellular processes.

Both types of oral contraceptives improved symptoms and hormone levels in women with PCOS.

Hormonal imbalances, often indicating conditions like PCOS, are common in women with hard-to-treat acne, and a treatment approach addressing these imbalances may be needed.

Spironolactone, a heart and liver drug, has new uses including cancer treatment, viral infection prevention, and skin condition improvement.

The HOXC13 gene affects different hair proteins in cashmere goats in varied ways and is controlled by a feedback loop and other factors.

The study suggests certain ACE gene variations are more common in women with PCOS and may be linked to increased insulin resistance.

The conclusion is that young women with excessive hair growth should be quickly tested for hormonal issues and treated to improve their social well-being.

Scientists found genes linked to the growth of high-quality brush hair in Chinese Haimen goats.

The document concludes that treating androgen excess needs patience, managing expectations is important, and many drugs used are not officially approved, suggesting cosmetic options for mild cases.
