There's no false hope. male pattern baldness is simply unpredictable and could go either way.Man. I am sorry to read this. Age 13 is WAY too young to experience hair loss. You absolutely cannot use finasteride at that age.
You can always try minoxidil and dermarolling but honestly your hair loss is extremely aggressive and I think odds are you won't make it to 18 before it is too late. I hate saying that but I don't want to give you this false hope.
