How Long Should You Leave Texturizer in Your Hair?
Application instructions can vary by product, but most texturizers are left on the hair for a short time, typically 5 to 10 minutes. If the texturizer is left on too long, it may straighten the hair as opposed to just loosening curls.
A texturizer is a mild relaxer that loosens curl patterns in hair. The result is loose waves rather than tightly coiled spirals. A texturizer makes hair easier to comb and style without causing breakage, and they can reduce frizziness and bulkiness. Texturizers are somewhat safer than relaxers because they are left on the hair for a shorter period of time.
