What is a common component in products that claim to be 'no lye'?

• A. Sodium hydroxide
• B. Guanidine hydroxide
• C. Calcium sulfate
• D. Ammonium thioglycolate

Answer: (B)

Products that claim to be 'no lye' typically use guanidine hydroxide as a key component. Unlike sodium hydroxide, which is a traditional lye used in many chemical relaxers, guanidine hydroxide is a gentler alternative that still effectively relaxes and straightens hair. It is often favored for its lower pH, which helps reduce the risk of scalp irritation and damage to the hair.

Having guanidine hydroxide in these products allows them to cater to clients looking for a less harsh option for chemical texturizing, while still providing effective results. This is particularly important for individuals with sensitive scalps or those with previously processed hair that may require a milder formulation. The use of guanidine hydroxide allows for effective chemical relaxation without the more direct alkalinity and potential damage associated with sodium hydroxide.
