Male pattern baldness is linked to higher levels of a certain receptor in the scalp, which leads to the shrinking of blood vessels and hair loss. Early treatment targeting this receptor could be more effective.
DHT may inhibit hair growth by affecting mitochondrial function, leading to hair follicle miniaturization. Treatments like minoxidil and PP405 may promote hair growth by altering metabolic pathways, potentially counteracting DHT's effects.
Dutasteride 0.5 mg significantly reduces both scalp and hair follicle DHT, with a greater reduction in hair follicle DHT. The discussion questions which reduction is more important for androgenetic alopecia and diffuse thinning.
PP405 and GT20029 are new hair loss treatments with different mechanisms from traditional options like Minoxidil and Finasteride. PP405 targets hair follicle stem cells to reactivate growth, while GT20029 works as an androgen receptor deleter, both requiring ongoing use for effectiveness.
The conversation discusses reducing scalp DHT to prevent hair loss, with a focus on using dutasteride, finasteride, and other treatments like RU58841 and minoxidil. It highlights the challenges of managing hair loss while on high testosterone levels, suggesting that dutasteride may be more effective than finasteride in such cases.
