How is the scalp typically prepped for a chemical treatment?

Preparing the scalp for a chemical treatment involves ensuring that it is clean and dry, which is essential for the effective and safe application of the product. A clean scalp allows for better product absorption, ensuring that the chemicals can penetrate the hair and scalp properly without interference from dirt or excess oils. Additionally, drying the scalp prevents any dilution of the chemical treatment and minimizes the risk of an adverse reaction.

While other methods, such as massaging with oils, applying a protective cream, or using a scalp exfoliant, may have their respective benefits, they do not primarily focus on the fundamental necessity of having a clean surface for chemical penetration. A protective cream, for instance, is used to shield the skin from chemical burns but does not address the initial cleanliness and dryness required prior to any chemical treatment.
