Do not perform a curl reformation service on a hair that has been relaxed with sodium hydroxide or a no-lye relaxer. Using a thio-base product on hydroxide-treated hair will result in severe hair damage and breakage dice these 2 chemicals are not compatible
Begins with straightening product is applied to the hair
The two major types of relaxer chemicals are sodium hydroxide and ammonium thioglycolate
Do not perform a curl reformation service on hair that has been relaxed with a sodium hydroxide or no-Lye relaxer
