What type of hair is sensitive to chemical relaxers?

Fine hair is particularly sensitive to chemical relaxers due to its structure and lower density compared to other hair types. When chemical relaxers are applied, they work by breaking down the disulfide bonds in the hair to alter its texture. Fine hair, having a thinner cuticle layer, can become damaged more easily during this process. If fine hair is subjected to harsh chemicals, it may lead to breakage or excessive dryness, as it does not have as much protection or resilience against the harsh effects of the relaxers.

Understanding the sensitivity of fine hair to chemical treatments is essential for hairstylists, as it guides them in choosing the correct products and approaches for safe and effective hair processing.
