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.
Multi-textured perms replicate the look of naturally curly hair and create the illusion of multiple layers and thicker, fuller hair. Stylists create this look using a combination of small and large perm rods. The result is a cascade of loose, easy-to-style curls. This perm is ideal for long hair and adds movement and buoyancy to limp, lank locks.
