Final answer:
No mix-no lye relaxers are hair care products that are sold as an alternative to traditional relaxers containing lye. They use alternative ingredients to break down the protein structure of the hair and straighten it. This is a topic in chemistry.
Step-by-step explanation:
No mix-no lye relaxers are often advertised and sold in the context of hair care products. These relaxers are specifically used to straighten curly or frizzy hair. They do not require mixing with chemicals like traditional relaxers, which often contain lye. Instead, no mix-no lye relaxers use alternative ingredients such as guanidine hydroxide or calcium hydroxide. These ingredients work to break down the protein structure of the hair, allowing it to be chemically straightened.
