What should be avoided during a hair color treatment?

During a hair color treatment, avoiding high pH products is essential because they can cause the hair's cuticle to lift excessively. A high pH can lead to increased porosity, which allows color to penetrate too quickly and can result in uneven color distribution, damage, and dryness. The optimal pH for most hair color treatments is slightly acidic, which helps to keep the hair cuticle closed and ensures a more balanced and effective coloring process.

Rinsing with cold water, on the other hand, can help to seal the cuticle after the color is applied, locking in moisture and promoting shine. Applying color to previously colored hair might be necessary for some clients, especially if they are having their roots touched up or looking for a refresh. Using a conditioner after coloring can also be beneficial, as it helps to moisturize and protect the hair post-treatment.

Therefore, maintaining a balanced pH level during a hair color treatment is crucial for achieving the best results without damaging the hair.
