What type of hair may require a stronger relaxer formula?

Coarse or very curly hair types typically require a stronger relaxer formula due to their natural structure and resistance to chemical processes. This hair type often has a tighter curl pattern and a more robust cuticle layer, which makes it more resilient against the effects of chemicals used in relaxers. The stronger formula can penetrate the hair shaft more effectively, breaking down the bonds that create the curl pattern, resulting in a smoother, straighter finish.

In contrast, fine or thin hair types generally need milder relaxers, as they are more susceptible to damage from stronger chemicals. Medium-textured hair can manage with moderate formulations, striking a balance between effectiveness and hair health. Color-treated hair is another consideration since it may have already been compromised by previous chemical processes, requiring a gentler approach with relaxers to avoid additional damage. Thus, coarse or very curly hair types necessitate a stronger formula to achieve the desired results effectively and safely.
