In Vitro Effects of Testosterone, Dihydrotestosterone, and Estradiol on Cell Growth of Human Hair Bulb Papilla Cells and Hair Root Sheath Fibroblasts

Hair loss is influenced by follicle sensitivity to DHT, which increases with age, rather than just testosterone levels. Treatments like finasteride and hair transplants are used to manage hair loss, with transplants needing medication to protect surrounding sensitive hair.

Dutasteride and finasteride are used for hair loss, affecting hormone levels like DHT and testosterone. Hormone balance is crucial, as changes can lead to side effects such as increased estradiol and potential hair loss.

DHT is essential for androgenetic alopecia, not testosterone. Treatments like finasteride and dutasteride reduce DHT, halting hair loss.

The conversation is about managing hair loss while on testosterone replacement therapy (TRT). Suggestions include using finasteride or dutasteride to address high DHT levels, with considerations on the impact of TRT on hair loss.

The user experienced side effects from finasteride and found improved mood and performance with DHT, but it worsened hair loss. They are considering options like TRT, HCG, and topical treatments like Saw Palmetto, but struggle with balancing hair preservation and functionality.

Testosterone can still cause hair loss even when DHT is blocked by dutasteride, especially if hair follicles are sensitive. Topical treatments like RU58841 or pyrilutamide may help, but their long-term effectiveness is uncertain compared to dutasteride.
