Relaxers are chemical products used to straighten curly or wavy hair. They work by breaking down the protein structure of the hair, allowing it to be reshaped into a straighter form. Relaxers come in different types, including lye and no-lye formulas, each with varying strengths and application methods. The process of using a relaxer typically involves applying the product to the hair, allowing it to sit for a specific time, and then rinsing it out. Afterward, a neutralizing shampoo is often used to stop the chemical process. Proper application and care are essential to minimize damage and maintain hair health.
