If I have something curly can you un-perm it ?
You can either have a chemical relaxer put on your hair or you can flat iron it. Both are rough on he hair (if you flat iron every day). A chemical relaxer relaxes curly or frizzy hair for a period of time (depending on how you upkeep your hair, outside of the salon)
p.s. What is curly, you said you have pin straight hair?
