The Basic Science of Hair Biology

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.

Miniaturized hair can potentially regrow unless the follicle is destroyed, with treatments like finasteride, minoxidil, and lifestyle changes playing a significant role. Some users report success with additional treatments like estrogen, ketoconazole, and derma stamping, emphasizing the importance of routine and overall health.

The conversation discusses hair regrowth and miniaturization, with the user transitioning to oral dutasteride and oral minoxidil, and occasionally using topical minoxidil. The user observes baby hairs near the hairline but less on the scalp, indicating possible regrowth and shedding.

A 25-year-old male experiencing hair loss suspects stress-related alopecia and is hesitant to use Minoxidil due to potential side effects. Another user suggests it might be androgenic alopecia and recommends starting finasteride.

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.

The user has been using finasteride for 16 months, minoxidil for 11 months, and started microneedling 2 months ago, experiencing shedding phases. They are questioning whether they are experiencing miniaturization or regrowth.
