Which of the following relaxers is more suitable for sensitive skin?

Guanidine hydroxide relaxers are considered more suitable for sensitive skin primarily because of their formulation. They are designed to be less irritating than other types of relaxers, specifically those that contain sodium hydroxide or calcium hydroxide, which can cause significant irritation and discomfort on sensitive skin types.

Guanidine hydroxide relaxers operate at a slightly lower pH level compared to traditional sodium relaxers, leading to a gentler process that is less likely to cause scalp burns or irritation. They work through a two-part system, which includes a base and an activator, providing control over the strength and effectiveness of the chemical process. This controlled environment helps minimize irritation while still allowing for effective hair straightening.

Moreover, because of their milder nature, guanidine hydroxide relaxers have gained popularity among clients with sensitive scalp and skin issues, making them a preferred choice for individuals who may experience adverse reactions to harsher chemicals.
