>>40159315Yeah it's alopecia if it's genetic, though there are two types of alopecia. One is autoimmune I assume based on your picture its not that. It's mainly passed down through female genes to males.

This article explains basically that instead of your hair being immune to dht but pushed upwards through the replication of hair cells, based on the dht's interaction with the skin/scalp under the hair---the hair itself is sensitive to dht (Due to a specific enzyme your genes overproduce) and the skin is unresponsive because it's oversaturated/the cells there we to become hair break when trying to create the hair follicle. There is an 'overproduction' of testosterone then due to scalp sensitivity. The laser targets the skin clearing the androgens, allowing for blood and nutrients to flow in the scalp and making way for new skin cell growth -> hair cell growth without getting choked by old and dead androgen dense cells.
