I'm 18 years old and am experiencing hair thinning. I use to have thick but fine hair. Since my senior year in high school my hair started to thin. I feel less and less hair. My ponytails are thin not filled with a good amount of hair like it used to. I need help do not know what to do and am scared. I have never dyed my hair and I don't use to much of gel or mouse on my hair. I miss my head full of hair. Can someone help me!!!!!!!!

well you did not say if you were male or female ??

But I know people who at 18 were solid gray and by 25 almost bald.

Have you been to a doctor to see about it
