What is a hydroxide relaxer?

A hydroxide relaxer is classified as a chemical product used in the hair relaxing process that permanently alters the structure of the hair. It works by breaking the disulfide bonds, which are the strong connections that give hair its shape and curl. By breaking these bonds, the hydroxide relaxer allows the hair to be reshaped into a straighter form, effectively reducing the curl and volume.

Hydroxide relaxers typically come in two forms: sodium hydroxide and calcium hydroxide, among others. These relaxers are known for their efficacy in relaxing even the most resistant curl types, providing a long-lasting straightening effect. It is important to use them correctly, as the strong chemicals can damage the hair if misapplied.

The other options do not accurately describe the function or nature of a hydroxide relaxer. For example, temporary relaxers do not provide a permanent change, and lotions that nourish the hair or straightening serums without chemical impact do not function in the same way as hydroxide relaxers, which are specifically designed to change the hair's structure chemically.
