When I mention to my stylist a want a hair perm she gapes in horror, since she was a teen in the 80's I guess she saw a lot of bad perms. I think a nice loose wavy perm would be pretty, she tells me they are uber damaging, are they really THAT bad? I have colored my hair before.
Perms break the disulfide bonds in hair so, yeah, they're pretty damaging. I'd rate perms as more damaging than coloring your hair but less damaging than relaxing.
