What is the main concern when using a chemical relaxer on curly hair?

The main concern when using a chemical relaxer on curly hair is the risk of overprocessing and damage. Chemical relaxers work by breaking down the protein structure of the hair to alter its curl pattern. If the relaxer is left on for too long or if the hair is subjected to multiple treatments without adequate care, it can lead to significant damage. This can manifest as dryness, brittleness, or even breakage of the hair strands.

It's important for stylists to accurately assess the hair's condition and choose the right formulation, as well as to adhere to timing guidelines to minimize any adverse effects. Proper aftercare and using moisturizing treatments can help mitigate potential damage; however, the inherent risk involved in altering the natural structure of curly hair remains the primary concern when applying chemical relaxers.
