How should hair be prepared prior to a chemical relaxer application?

Prior to a chemical relaxer application, hair should be dry and detangled. This preparation step is essential because chemical relaxers work most effectively when they are applied to hair that is in its natural state, without excess moisture which can dilute the product. Having the hair dry allows for better absorption of the relaxer and more uniform results. Additionally, detangling ensures that the relaxer can be applied evenly and helps to prevent breakage and damage during the application process. It is crucial to have the hair free from knots and tangles to facilitate smooth product distribution and to achieve the desired chemical straightening effect.

Other methods of preparation, such as using water, oil, or specific shampoos, can interfere with the chemical process and may lead to inconsistent results or hair damage. Therefore, starting with dry, detangled hair is the best approach to ensure a successful chemical relaxer application.
