What is a critical step to avoid during the application of relaxers?

Overlapping the relaxer on previously relaxed hair is a critical step to avoid during the application of relaxers because it can lead to significant hair damage. When relaxers are reapplied to hair that has already been relaxed, it can weaken the hair shaft and cause excessive dryness, breakage, and overall compromised hair integrity. The chemicals in relaxers break down the protein structure of the hair, and applying them to already relaxed sections can alter the hair's texture, leading to inconsistent results and potential harm to the hair.

This principle is essential for maintaining healthy hair and achieving the desired look without unintended consequences. Proper technique involves carefully applying the relaxer only to the new growth—the hair that hasn’t been treated—ensuring that the rest of the hair remains undamaged. By focusing on this practice, stylists can provide a safer and more effective hair relaxing experience.
