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.
NOt only can you dye it but you can perm it! LOL My first cancer battle was nearly 13 years ago and perms were all the rage, when I had enough hair I had it permed no problem. I dye my hair regularly you should be fine! Hugs.
