I love playing with my hair, and i am always running my fingers through it. Until one day i began scratching my head/hair. I really liked the smell of it, so it turned into a habit. Now my friends and family think its an anxiety or compulsive issue. I make the habit less noticeable in public, but alone i can't stop scratching. AS and anxiety/compulsive habit, is this normal? I realize, otherwise, its weird.
