I know what you mean. It's called obcessive/compulsive. Might I suggest therapy? JKRed
its only a disadvantage in the sense that I cant stand it. plus my head gets some type of bumpy scaley feel to it once the hair gets a couple mm's long (like a day and a half + out) That is the main thing leading me towards laser removing it all so i can have that perfect smooth all day long and no dermatitis on my scalp. I think its called seborhheic dermatitis.
I have always dealt with different forms of skin irritation from acne to this.
