Endocrine Regulation of Hair Growth and Loss: Current Evidence and Clinical Implications

DHT promotes beard growth but causes scalp hair loss due to inflammation and fibrosis. Treatments like finasteride and minoxidil help with hormonal signals and blood flow but don't address underlying inflammation.

Hair loss treatments discussed include finasteride, minoxidil, spironolactone, and estradiol, with concerns about side effects like sexual dysfunction and feminization. Some users prefer hair transplants or shaving over medication due to potential side effects.

Using estrogen for hair regrowth is considered ineffective and risky, with potential side effects like breast growth and hormonal changes. Alternatives like finasteride, dutasteride, and minoxidil are suggested, but estrogen is not recommended unless transitioning.

A 24-year-old male using topical finasteride for hair loss is experiencing thinning despite treatment and has high estrogen levels. He is seeking advice on whether high estrogen could be causing hair loss and how others with high estrogen levels have addressed it.

Prolactin and cortisol are identified as key factors in hair loss, with stress hormones impacting hair shedding. Finasteride and minoxidil are effective treatments, while DHT's role and individual sensitivity are significant factors.

The user experiencing diffuse hair loss is using various treatments including RU58841, finasteride, minoxidil with tretinoin, anti-hair loss shampoo, and microneedling, and is considering adding peptides TB500, BPC157, and GHK-Cu. They have low growth hormone levels and are questioning its impact on hair loss, while another user suggests androgenic alopecia and androgens are likely the main cause of hair loss.
