Hey doctor I am a 18 years old male been losing hair for over a year. My hairline is going up and I believe I am thinning. My mother and brother started thinning at the same time. What can it be?
I really can’t tell you without examining you. There are many things that I look for which include miniaturization, a HAIRCHECK (see here: https://baldingblog.com/2017/01/10/value-haircheck-bulk-measurements-two-patients-seen-today/) and possibly some blood tests considering that the hair loss is in the family as well. It might be something in your water system, but I would first look to genetic balding as that is the most common form of hair loss in young men. Your recession might simply be the development of a mature hairline which happens about your age.
