Microneedling stimulates hair growth through stem cell activation during wound healing, not just increased blood flow. Other methods like showers or supplements don't replicate this effect.
The conversation is about which blood markers to test before starting a 5-AR inhibitor for hair loss. The user mentions already testing Total T, Free T, SHBG, Estradiol, Haematocrit, Redbloodcell count, and White cell count, and asks if DHT or additional markers are needed.
Hair follicles are mostly dormant but can be reactivated with treatments like minoxidil, finasteride, and microneedling. A new drug, PP405, shows promise for hair regrowth but may not be available until 2027-2028.
Intense microneedling with heavy pressure and bleeding did not improve hair growth after 4 months. The user advises against this method, noting no benefits and potential harm, and mentions using minoxidil without success.
The user started using finasteride, minoxidil, and biotin for male pattern baldness (MPB) and is experiencing rapid thinning. They are questioning if low blood flow to the head could be contributing to their hair loss.
