During a chemical relaxer service, how is the product usually applied?

The application of a chemical relaxer is typically done using a brush or applicator for several important reasons. This method allows for precise control over the amount of product being applied and helps to ensure even distribution throughout the hair strands. The brush or applicator can effectively reach the roots and cover the hair uniformly, which is crucial for achieving the desired straightening effect consistently across the entire head.

Using a brush or applicator also minimizes the risk of over-processing certain areas of the hair that might occur with other application methods. The aim is to relax the hair's natural curl pattern effectively while maintaining the integrity of the hair, and applying the product evenly contributes significantly to this goal.

In contrast, using a cotton pad would not provide the necessary control or even application required for such a potent chemical process. Applying with fingertips only may lead to uneven distribution and potential damage to certain sections of the hair. Lastly, applying the relaxer in one go without sectioning could make it difficult to ensure thorough coverage and may also result in uneven processing, as different areas of the hair have different porosities and textures. Thus, using a brush or applicator is the best practice for a successful chemical relaxer service.
