neutralizer or neutralizing shampoo
Before styling the hair following a relaxer process, you should:

Do not perform a curl reformation service on hair that has been relaxed with a sodium hydroxide or no-lye relaxer.
The chemical phase of relaxing consists of smoothing/combing the hair and timing and testing the process.
Sodium hydroxide relaxers have a pH of 10.5-14.
The two major types of relaxer chemicals are sodium hydroxide and ammonium thioglycolate
Never apply a thio relaxer over hair that has been relaxed with a sodium hydroxide relaxer or vice versa, since these two chemicals are not compatible and severe damage or breakage can occur.
Spreading the chemical relaxer through the hair with the back of a comb or your fingers as it processes is called smoothing.
When performing a curl reformation service, the rod diameter chosen is generally at least two times larger than the diameter of the natural curl pattern.
Density refers to the number of hair follicles per square inch.
Clients with wavy hair have an oval-shaped hair follicle.
Elasticity refers to the ability of the hair to absorb moisture, liquids or chemicals.
Do not apply sodium hydroxide relaxer to hair that has been colored with permanent hair color or to lightened hair.
During a relaxer application, it is important to use an acid-balanced neutralizing shampoo or stabilizer to reharden the hair into its new, straight shape.
