What hair type should avoid strong alkaline relaxers?

Fine or damaged hair should avoid strong alkaline relaxers because these relaxers can cause significant chemical damage to the hair structure. Fine hair is typically more fragile and prone to breakage compared to coarse hair types. Using strong alkaline products can lead to overstressing the hair cuticle, making it more susceptible to losing moisture and elasticity. This could result in severe dryness, brittleness, and ultimately hair breakage.

In the context of hair textures, the other options represent hair types that may handle stronger relaxers more effectively. Coarse and thick hair, for instance, has a more resilient structure and can generally withstand the harsher effects of alkaline relaxers. Curly and thick hair may also have the resilience needed to endure strong relaxers. Short and straight hair does not necessarily indicate a lack of strength but rather a length characteristic. Therefore, fine or damaged hair is the most sensitive to the aggressive nature of strong alkaline relaxers and should opt for milder alternatives to protect its integrity.
