What type of relaxers do not contain sodium hydroxide?

• A. Lye relaxers
• B. Non-lye relaxers
• C. Thio relaxers
• D. Keratin relaxers

Answer: (B)

Non-lye relaxers are formulated without sodium hydroxide, making them a gentler alternative for hair relaxation. These relaxers often utilize calcium hydroxide or guanidine hydroxide, which can provide similar straightening effects without the harshness associated with sodium hydroxide-based relaxers. This gentler formulation can be less irritating to the scalp and is often preferred by individuals with sensitive skin or hair that is already chemically processed. Additionally, non-lye relaxers are compatible with more hair types and textures, making them a versatile choice in the cosmetology field. Understanding the different types of relaxers and their ingredients is crucial for professionals looking to meet the varying needs of their clients effectively and safely. Many other relaxers, including lye and thio relaxers, contain sodium hydroxide or other harsher chemicals, which can pose a risk for irritation or damage, especially on already compromised hair.
