A Hairmet is a head covering used to protect the head while cycling, except while a helmet fits directly on top the hair, messing up the hair, the hairmet will protect the user's hairstyle keeping them looking good for the day ahead. J.D. likes to wear hairmets, to Dr. Cox's chagrin. ("My Lucky Night") ("My Déjà vu, My Déjà vu")
