What is the correct application method for a relaxer?

The correct application method for a relaxer involves applying it from the roots to the ends. This method is essential because the hair closest to the scalp, where new growth occurs, typically has more natural texture and may require more time for the relaxer to work effectively. The heat from the scalp also intensifies the relaxer's effectiveness, allowing it to penetrate better and more evenly at the roots. By starting at the roots, the stylist can ensure that the most textured sections are treated properly, and then they can work the product down through the mid-lengths and ends to ensure even distribution.

Applying from the ends to the roots or randomly to sections can lead to uneven results, as the ends, which are older and often more porous, could become over-processed while leaving the roots under-relaxed. Likewise, focusing only on the mid-lengths ignores the crucial roots, resulting in a less uniform texture.
