Male Baldness Info

I’m an 18 year old male.I saw a dermatologist and he said I have male pattern baldness.I don’t believe that only 2 people have lost their hair in my family and its my uncles on my moms side.I don’t want to take propecia or Rogaine.The dermatologist and my usual doctor didn’t even give me a thyroid or blood test.So how can they know just by looking at my hair and knowing that 2 people in my gigantic family that I have male pattern baldness.They said I could either take Propecia and Rogaine or get a hair transplant or just watch my hair fallout.I think its best that I start eating healthy and stop eating all junk food including sodas and trying out All Natural and Organic Shampoo and expose my hair more to sunlight and excercise and massasing my scalp 5 minutes a day.

This guy is in my class and he is under 25 and is going bald. He use to wear caps all the time then he stopped and thats when I saw his thining hair. I felt so sad for him, even though he was a pain and was cheating off people during test but I still felt sad because men cant really stop it .
So how do you feel or have you experienced it?
Remember you are attractive without the hair and you dont have to go completely shaved. We still love you all.
