What determines the strength of a chemical relaxer?

• A. The Concentration of Hydroxide
• B. The pH Level
• C. Both The Concentration of Hydroxide and The pH Level
• D. The Temperature of the Hair

Answer: (C)

The strength of a chemical relaxer is governed by how aggressive the formula is, which comes from two main factors: the amount of hydroxide present and how alkaline the solution is (its pH). The hydroxide concentration provides the actual reactive ions that break the disulfide bonds in the hair; more hydroxide means more bond disruption and a stronger relaxing action. The pH indicates how alkaline the formula is, which affects how easily the hair swells and how effectively the bonds are opened. Together, higher hydroxide levels and higher pH lead to a stronger relaxer. Temperature of the hair can influence how fast the reaction happens, but it doesn’t determine the inherent strength of the relaxer itself.
