Yes they do damage hair. Every time I have tried one ,I wound up looking like a Q-tip or my head looked like cotton. A perm will damage even more and look worse if you have been coloring your hair. There's chance of it looking okay if you don't color your hair.
A perm (short for permanent wave) , is a chemical hair treatment that can be used to change the natural style of hair. Folowing the 1980s perms have been less acceptable for men following the styles supported by footballersat that time falling out of fashion. While a matter of personal taste, perms can look good on a man if the tightness of the curls and length of the hair is matched sympathetically to the shape of the head and other facial features (stubble beard for example).
