Question: 1 / 400

What could be a sign of an allergic reaction to a hair product?

Change in hair color

Increased shine

Itching or redness on the scalp

Itching or redness on the scalp is an important indicator of an allergic reaction to a hair product. Allergic reactions often manifest through irritation and inflammation of the skin, particularly at the site of contact. In this case, the scalp is directly exposed to various hair products, which can contain chemicals or allergens that trigger a sensitivity reaction. This symptom serves as a warning sign that the body is reacting defensively to a substance it identifies as harmful.

Recognizing these signs is crucial for anyone working in cosmetology as it directs them to either switch products, recommend patch tests, or refer clients to dermatological help when necessary. Additionally, the presence of such symptoms underscores the need for cosmetologists to be aware of the products they use and to communicate effectively with their clients about potential allergic reactions.
