Estradiol is a naturally occurring steroid hormone and the most important of the oestrogens, which is mainly produced in the ovaries of women. In addition to its central role in regulating the menstrual cycle and reproduction, estradiol also has significant effects on the skin and hair.
In relation to hair, estradiol promotes hair growth and helps to prolong the anagen phase (growth phase) of the hair cycle, allowing hair to grow longer before moving on to the next phase. It improves hair quality by strengthening and supporting the hair follicles, resulting in a thicker and stronger hair structure.
Another important aspect of estradiol is its role in regulating sebum production in the scalp. A balanced production of sebum is essential for the health of the scalp and prevents both dryness and excessive oiliness, which can promote hair growth.
During the menopause or in the case of hormonal imbalances, a decrease in estradiol can lead to increased hair loss. This is a common cause of hair loss in women after the menopause. By regulating hormone levels, estradiol can help prevent or slow down androgenetic hair loss as it counteracts the effects of dihydrotestosterone (DHT), which is responsible for the shrinkage of hair follicles.
In summary, estradiol is an essential hormone for hair health and growth. It promotes hair growth, improves hair quality and protects against hormonal hair loss, especially in women. A lack of estradiol can lead to various hair problems, particularly in connection with the natural ageing process and hormonal changes.
