Neutralizing is the final chemical step in the perm process. It reforms the disulfide bonds while lowering the pH of the hair. The main ingredient found in most neutralizers is hydrogen peroxide, sodium perborate or sodium bromate. The pH can range from 2.5 to 7, depending on the type on neutralizer.
What is perm neutralizer?
In a standard “cold” perm, hair is put into curlers and the reducing agent ammonium thioglycolate is added. … Then a “neutralizer,” such as hydrogen peroxide, is added to reverse the effect of the reducing agent. New disulfide bonds form so the keratin molecules are locked into the shape of the curls.

What is no-lye relaxer?
What is No-Lye Relaxer? Opposite of the lye relaxer, a no-lye relaxer has calcium hydroxide in it or otherwise known as guanidine hydroxide. While it’s true the pH levels are lower is a lye relaxer, no-lye relaxers sometimes dry the hair out mainly because of the calcium content and buildup.
What products are used in sodium hydroxide relaxers?
Alkaline and lye relaxers The scalp can suffer severe chemical burns if over exposed to lye or no-lye relaxers. A lye relaxer consists of sodium hydroxide (also known as NaOH or lye) mixed with water, petroleum jelly, mineral oil, and emulsifiers to create a creamy consistency.
What is the difference between Thio and hydroxide relaxers?
Thio relaxers differ from hydroxide relaxers in a few ways. The pH of thio relaxers is typically around 10 whereas the pH of hydroxide relaxers is approximately 13. Also, an oxidizing agent like hydrogen peroxide or sodium bromate is used to neutralize thio relaxers.

What is a sodium hydroxide relaxer?
A – Sodium hydroxide (lye) relaxer – used to straighten tightly curled hair. This type of relaxer is alkaline in pH (11.5 to 14), which forces the cuticle to open so that the relaxer can penetrate in the cortex layer of the hair. Once there, the sodium hydroxide breaks down the cross bonds (sulfur and hydrogen).
Which relaxer is better lye or no-lye?
