Transplantation of live hair follicles made from one's own hair is the safest method. The most resistant area against hair loss is the nape and temporal area, so live hair follicles are taken from this area.
In men, hair loss is usually associated with the male hormone and can show a genetic transition. This is called androgenetic alopecia. Rotation of testosterone in the body to dihydrotestosterone (DHT) in androgenetic alopecia results in loss of sensitive hair follicles.
