My friend is considering a straight perm but he doesn’t wanna do it, if itâs going to look odd. His hair is naturally super curly. Like ringlets. So, he straightens it everyday unless he isn’t going anywhere. The only thing he’s ever done is straighten it. He has never dyed his hair. Would this kill his hair? If perms really do last 6 months isn’t that better than straightening it every day for 6 months?
