In this article, we will delve into the details of what a 40 developer is, its uses, the potential risks associated with it, and most importantly, whether it is safe to use.
Introduction to Hair Developers
Hair developers, also known as hair bleach or oxidizing agents, are crucial components in the hair coloring process. They work by opening up the hair cuticle, allowing the color to penetrate and deposit into the hair shaft. The most common hair developers are hydrogen peroxide-based, with different volumes indicating the strength and potential lightening power of the developer. The volume of a developer refers to the amount of oxygen it releases, which in turn affects how much the hair will lighten.
What is a 40 Developer?
A 40 developer is a high-lift hair bleach or developer that contains hydrogen peroxide in a concentration that can significantly lighten the hair. It is considered strong and is used for dramatic color changes or for lifting very dark hair several shades lighter. The “40 volume” refers to the percentage of hydrogen peroxide in the solution, which is 12%. This strength is typically used by professionals for significant color corrections or for achieving very light shades.
