Hair Scare,
Southern Guy is right. If you have an itchy scalp even without a hair piece on it's a good idea to see a dermatologist. We don't recommend full head bonds. For newbies that are unfamiliar with the term 'full head bond' it means that all of the base of the hair piece is bonded to the head. Most hair wearers just bond the perimeter of the unit to the head. This is sufficient in almost all cases as the tapes and glues used today are strong.
Good luck!
