Dihydrotestosterone (DHT)

Dihydrotestosterone (DHT) is an androgen hormone, a derivative of testosterone, present in women's bodies at low concentrations. When DHT levels are excessive, this hormone can shrink hair follicles, shorten the anagen (growth) phase, and prolong the telogen (shedding) phase. This process results in gradual hair thinning, particularly noticeable on the crown of the scalp and along the hair part.

Estrogen

Estrogen helps hair maintain a prolonged growth cycle, promoting thick, long hair. It can also prevent testosterone from converting into DHT within hair follicles. A decline in estrogen levels, such as during menopause, leads to hair thinning and increased shedding.

Progesterone

This hormone regulates the menstrual cycle and supports pregnancy. Similar to estrogen, progesterone inhibits the conversion of testosterone to DHT. Low progesterone levels can increase DHT on the scalp, contributing to hair loss.

Cortisol

Elevated cortisol levels, often triggered by emotional or physical stress, can lead to a temporary form of hair loss. Practicing deep breathing exercises, meditation, yoga, tai chi, or mindfulness can help relax the nervous system and manage stress.

Thyroid hormones

The thyroid gland produces hormones essential for metabolism and overall bodily function, including the health of hair follicles. Both hypothyroidism (low thyroid hormone levels) and hyperthyroidism (high thyroid hormone levels) disrupt the hair growth cycle.

Insulin

This hormone regulates blood sugar. Insulin resistance or an insulin deficiency results in elevated blood sugar, which can damage blood vessels and reduce the supply of oxygen and nutrients to hair follicles. This can slow hair growth and promote hair thinning.

While hormone-related hair loss cannot always be prevented, lifestyle changes can contribute to maintaining hair health.

Reduce stress: Incorporate stress-reducing activities such as meditation, yoga, pursuing personal hobbies, and getting sunlight exposure to help lower cortisol levels.

Maintain a balanced diet: Consume nutrient-rich foods that support hormone production and overall health.

Exercise regularly: Physical activity helps regulate hormones like insulin and reduces stress.

Prioritize sleep: Aim for 7 to 8 hours of sleep each night to support hormonal balance and aid in health recovery.
