What type of relaxers are known as lye relaxers?

Sodium hydroxide relaxers are classified as lye relaxers because they contain sodium hydroxide as their active ingredient. This high-alkaline compound effectively breaks down the disulfide bonds in the hair, allowing it to be straightened. The use of sodium hydroxide can provide quick and long-lasting results, making it a popular choice for clients with coarse, curly hair types. However, it is essential for professionals to handle this chemical carefully due to its potency, which can lead to scalp irritation or damage if not applied correctly. Understanding this helps cosmetologists choose the right product based on the client's hair type and desired outcome.
