What action should you take if there are abrasions present on a client's scalp?

When abrasions are present on a client's scalp, the appropriate action is to refer to a physician. This ensures that the client receives the necessary medical attention for their condition, as abrasions can indicate underlying issues that may require treatment beyond the scope of cosmetology practices. Continuing with the service, cleaning the area, or applying any product could potentially worsen the client's condition or cause further irritation. It is vital to prioritize the health and safety of the client, making a referral to a medical professional the most responsible choice. This not only protects the client's well-being but also aligns with professional standards in the cosmetology field, where the health of the client should always come first.
