Hairloss in 18 year old? stress?

There are many reasons for losing hair at such a young age.What you are saying could be your Genes, even though your farther and uncle lost there's in their thirties you don't have to be around thirty for it to affect you.Also try eating more fruits and vegetables you can't substitute with pills forever it might also be the lack of vitamin A in your diet.You might also have a disease like an STD or Cancer.You are a boy so people won't really make fun of you for having a Bald head the best thing to do if your hair continues to recede is to cut all of it off, It might not grow back so you should wait until a-lot recedes also you could try changing your shampoo some of them have chemicals that are bad for your hair or they don't react "well" with your body.Also don't stress yourself out about it,it might really be your Genes since both your Dad and uncle lost theirs but you are losing yours earlier than them.You also get Chromosomes from both your parents so that's just because your mothers farther doesn't have it you will not either.Just live with it and people have there own opinions and you would be surprised how many of them are Bald, but it varies from country but just relax it might be normal for you and you should also talk to your doctor about it also TALK TO YOUR DOCTOR BEFORE YOU DO ANYTHING ELSE THAT I SAID BECAUSE HAIR LOSS HAS A SPECTRUM OR DISORDERS OR DEFICIENCIES THAT CAN CAUSE IT.
