Is it possible to START prematurely balding at the age of say, 17,18,19,20 or below the age of 25/30 if there is no family history of STARTING balding below the age of 35? Also, does hairline maturing occur at a similar time frame as predecessors or does it have it’s own time frame?
Genetic male pattern balding may start with puberty. You may be well on the way to being bald in your teenage years or in your 20s or 30s. Anything is possible. In general most significant genetic hair loss occurs in your 20s and 30s and usually the balding process slows down past 35.
You don’t have to have a “family history” because it does not completely follow a direct and predictable inheritance pattern.
