The world of hair care and chemical treatments can be complex and overwhelming, especially with the myriad of products and terms used in the industry. Two terms that are often confused with each other are “bleach” and “developer.” While they are related in the context of hair coloring and lightening, they serve distinct purposes and have different compositions. In this article, we will delve into the details of what bleach and developer are, their roles in hair coloring, and the key differences between them.
Understanding Bleach
Bleach is a chemical substance used to lighten or remove color from hair. It works by penetrating the hair shaft and breaking down the pigment molecules, thereby reducing the hair’s natural color. Bleach is commonly used in hair salons for various purposes, including lightening dark hair, removing existing color, and creating a base for further coloring treatments. There are different types of bleach, including powder bleach and cream bleach, each with its own set of characteristics and applications.
The Chemistry of Bleach
The primary active ingredient in hair bleach is hydrogen peroxide. When applied to the hair, hydrogen peroxide releases oxygen, which then breaks down the melanin (the pigment responsible for hair color) into smaller components. This process lightens the hair by reducing the amount of melanin present. The strength of the bleach is determined by its volume, which refers to the percentage of hydrogen peroxide it contains. Common volumes include 10, 20, 30, and 40 volume developer, with higher volumes being stronger and more effective at lightening hair.
Types of Bleach
There are several types of bleach available, each designed for specific applications and hair types. These include:
- Powder bleach: A highly effective and commonly used form of bleach. It is mixed with a developer to achieve the desired strength.
- Cream bleach: Less damaging than powder bleach, cream bleach is often used for lighter applications and is mixed with a developer in a similar manner to powder bleach.
Understanding Developer
Developer, often referred to as hydrogen peroxide, is a chemical used in conjunction with bleach or dye to activate and enhance the coloring or lightening process. It comes in different volumes, which determine its strength and the degree of lift it can achieve when used with bleach. Developer is not a bleach itself but works in tandem with bleach or color to open up the hair cuticle, allowing the color or bleach to penetrate more effectively.
The Role of Developer in Hair Coloring
Developer plays a crucial role in the hair coloring process. When mixed with bleach, it helps to break down the pigment in the hair, allowing for a lighter shade. When used with hair dye, it opens up the hair cuticle, enabling the dye to penetrate and deposit color more evenly. The choice of developer volume is critical, as it affects the final result of the coloring or lightening process. Using the wrong volume can lead to undesirable outcomes, such as over-processing, under-processing, or damage to the hair.
Choosing the Right Developer Volume
The volume of developer to use depends on the desired outcome and the condition of the hair. For example, a 10 volume developer is used for depositing color without lift, while a 20 volume developer is commonly used for general coloring and lightening. Higher volumes, such as 30 and 40 volume developers, are used for more significant lightening but carry a higher risk of damage to the hair.
Key Differences Between Bleach and Developer
While bleach and developer are both used in the hair coloring and lightening process, they are not the same thing. The primary differences lie in their composition, function, and application.
- Composition: Bleach contains ingredients designed to break down and remove pigment from the hair, whereas developer is essentially hydrogen peroxide, which activates and enhances the coloring or lightening process.
- Function: Bleach is used to lighten or remove color from hair, while developer is used to activate bleach or dye, allowing it to penetrate the hair more effectively.
- Application: Bleach is applied to the hair to achieve lightening, and developer is mixed with bleach or dye to facilitate the coloring or lightening process.
Importance of Understanding the Difference
Understanding the difference between bleach and developer is crucial for achieving the desired results in hair coloring and lightening. Misusing these products can lead to over-processing, under-processing, damage to the hair, and undesirable color outcomes.
