PP405 is not a cure for hair loss but may reactivate dormant hair follicles, similar to minoxidil. It is unlikely to help with miniaturized or vellus hairs and is still in trial phases, with availability expected around 2030.
Minoxidil was applied to a single miniaturized hair follicle over four months, resulting in less miniaturization but not yet terminal growth. The user used a 5% minoxidil solution, specifically the Regaine brand, and observed changes using a handheld WiFi microscope.
Hair loss treatments, such as minoxidil, finasteride, microneedling, ketoconazole shampoo and vitamins D3 and Omega 3, which appear to have been successful in regrowing hair on a user's temples that had been slick bald for 8-9 years.
Minoxidil helps hair growth by increasing blood flow and prolonging the growth phase, but it doesn't address the root cause of hair loss, such as DHT sensitivity. Finasteride can help maintain some gains by blocking DHT, but stopping Minoxidil often leads to hair loss because the new hairs are dependent on it.
A user started using RU58841 a month ago after using finasteride and minoxidil for nearly three years, hoping for hair regrowth at the temples. Other users suggest vitamin B supplements and microneedling to improve hair thickness, and one mentions the possibility of a hair transplant for the temples.
