Mild relaxers have a little bit less (not much) of the active ingredient than regular. In this manner, is there a safe hair relaxer? The short answer is no. There is no product completely free of chemicals that will permanently straighten highly textured hair. The reason that a traditional, lye-based relaxer is still around is because there’s no suitable replacement if you want to straighten tresses without reversion at the first sign of moisture.What are the different types of relaxers?There are three types of relaxers; sodium hydroxide, calcium hydroxide and ammonium thioglycolate. Sodium hydroxide relaxers are commonly called lye relaxers. Lye relaxers can be used on wavy, curly or coily hair.
