What should be avoided when selecting a hair treatment for chemically treated hair?

When selecting a hair treatment for chemically treated hair, it is crucial to avoid overlapping products on previously treated areas because this can lead to severe damage. When hair has already undergone chemical processes such as coloring, perming, or relaxing, the hair structure is altered and can be more fragile or susceptible to breakage. Applying additional products in those areas can exacerbate the stress on the hair cuticle, potentially leading to issues like excessive dryness, split ends, or even chemical burns.

In contrast, using moisturizing products, regular trims, and deep conditioning treatments can actually benefit chemically treated hair by providing hydration, maintaining shape and health, and enhancing the overall texture. These practices are aimed at nourishing the hair and helping to repair and fortify it against potential damage. Therefore, the emphasis must be placed on careful application and differentiation in how treatments are applied to protect the integrity of chemically treated hair.
