PSI Cosmetology Practice Exam

A scalp with abrasions is a clear indication that a chemical service should be avoided. Scalp abrasions suggest that the skin has suffered some form of injury or irritation, which can compromise the skin's protective barrier. Performing a chemical service, such as coloring or perming, on an area with abrasions can introduce harsh chemicals into the bloodstream and lead to severe irritation, allergic reactions, or infections.

In contrast, while a dry scalp, oily scalp, or even a normal scalp may present their own unique challenges or considerations for specific treatments, they do not pose the immediate risk to the integrity of the skin as abrasions do. Therefore, it's critical for the safety and well-being of the client to avoid any chemical services on a scalp with abrasions.
