Hi dr Rassman! thanks a lot for this wonderful site. I am wondering Ä±f you see some hair loss signs in your son, what will you do FIRST to treat it? and also, have you ever used concealers such as toppik, dermmatch, couvre….? can they effect the working of finasteride? thanks a lot.
If my son had early miniaturization, I would immediately start him on Propecia. That is what I did with one of my three sons. The use of concealers should not impact finasteride.
