The effectiveness of a chemical hair relaxer is significantly influenced by the hair's porosity and texture. Porosity refers to the hair's ability to absorb moisture and chemicals; hair with high porosity will absorb relaxers more quickly and may process differently than hair with low porosity. Additionally, the texture of the hair—such as whether it is coarse, medium, or fine—determines how the hair will react to the relaxing agent. Coarse hair often requires different processing times compared to fine hair due to its structural differences. This understanding is vital for a cosmetologist to achieve the desired results while maintaining hair health.

Other factors, while they may seem relevant, do not impact the chemical process as directly as porosity and texture. The color of the hair might affect the initial appearance of the relaxer, but it does not influence the chemical reaction. The length of the hair might relate more to how much product is needed but does not alter the outcome of the relaxer itself. The time of day is irrelevant to the chemical interaction that occurs between the relaxer and the hair.
