What is an important consideration when applying relaxers to different hair types?

When applying relaxers to different hair types, understanding how coarse hair may tolerate a longer processing time is crucial. Coarse hair has a thicker cuticle layer, which can make it more resistant to chemical treatments. As a result, it often needs a longer duration to ensure that the relaxer effectively penetrates and alters the hair's structure. This consideration helps in achieving an even and desired level of straightness without causing excessive damage to the hair.

In contrast, fine hair requires more careful handling and may be more vulnerable to over-processing; thus, it is advisable to use a milder formula and shorten the processing time. Therefore, recognizing the specific characteristics of hair types allows for more effective and safe application of relaxers.
