Which type of mixing bowls may weaken peroxide when used?

Mixing bowls made of metal can weaken peroxide when used during the hair coloring process. This is primarily due to the chemical reaction that can occur between the metal and the peroxide. Peroxide is an oxidizing agent, and when it comes into contact with certain metals, it can cause a reaction that diminishes the effectiveness of the developer.

In contrast, mixing bowls made from plastic, glass, or wood are generally inert and do not interact chemically with the peroxide, maintaining its potency and effectiveness during application. Using non-metallic bowls ensures that the peroxide will perform as intended, leading to better results in hair color processing. This is an essential consideration for professionals when choosing the right materials for their services.
