hello brotha,
even i had similar loss when i was 20, now i am 23 and easily NW 3 and depressed.
Even i thought my hairline was maturing but sadly i was going bald.
DONT waste a single day start finasteride(either 0.5mg or 1mg by consulting the Doctor only)
Educate yourself about the meds and have them. The best would be maintain the hair that you have got now . BEST OF LUCK
