Hi,
your fater has
androgenic alopecia which has heridity predisposition, you have a tendency to develop that. but it normally occurs at later ages. you are 19 years and mentioned that you have so little hairloss.
there are about one lakh hair on our
scalp, which are in different phases of growth, about 100
hair fall in a day is normal. so dont worry . try out these things-
-take a high protien and
well balanced diet. avoid body building powders containing hormones as they can cause hair fall.
-avoid hair gel or hair cosmetics
-wash hair with shampoo at least twice a week
-use wide toothed comb ,
dont use hair driers regularly
use hair conditioners after shampooing.
these things will help you.
in case u are still concerned contact a dermat to start
minoxidil and other medications if required
