Chemical treatments are known to be a common cause of scalp irritation in clients. These treatments often involve the use of strong substances that can alter the structure of the hair and the condition of the scalp. For example, relaxers, perms, and hair dyes contain chemicals that can cause burns, allergic reactions, or sensitivity, especially if they are left on for too long or if the client has an underlying sensitivity to certain ingredients.

Additionally, improper application techniques or failure to follow safety guidelines can increase the risk of irritation. It is essential for barbers to conduct patch tests and communicate with clients about their hair history and any allergies to minimize the risk of reactions. While styling products, hair products, and heat tools can also contribute to scalp issues, they are typically less aggressive and more manageable compared to the potential adverse effects of harsh chemical treatments.
