How can barbers prevent allergic reactions to products?

Conducting patch tests before using new products is an effective way for barbers to prevent allergic reactions. This practice involves applying a small amount of the product to a limited area of the skin and observing for any adverse reactions, such as redness, itching, or swelling. This precaution allows barbers to assess a client's sensitivity to certain ingredients in the product, thereby minimizing the risk of a severe allergic reaction when the product is applied more broadly during a service.

This method is grounded in a proactive approach to client safety, ensuring that potential allergens are identified and avoided before any full application. Implementing patch tests not only helps maintain a safe and comfortable environment for clients but also protects the barber's professional reputation.
