Which relaxer is commonly marketed as no mix-no lye relaxers?

• A. Sodium hydroxide relaxers
• B. Guanidine hydroxide relaxers
• C. Lithium hydroxide relaxers
• D. Potassium hydroxide relaxers

Answer: (D)

Understanding no mix-no lye relaxers focuses on how the product is formulated and sold. These systems are designed to be ready to use without any mixing and to avoid the traditional lye base. Potassium hydroxide is commonly used in these one-step, premixed formulas, and it’s marketed as no mix-no lye because you don’t blend products or rely on sodium-based lye. The other bases listed—sodium hydroxide, lithium hydroxide, and calcium-based formulas—are traditional lye or mixed systems that don’t carry the same no mix-no lye labeling. Remember that, regardless of the base, a neutralizing step is still part of the process to restore the hair’s pH after relaxation.
