What is the primary difference between bleach and developer in hair care?
Bleach and developer are two commonly used chemicals in hair care, but they serve distinct purposes. Bleach is a strong alkaline substance that breaks down the pigment in hair, lifting it to a lighter shade. It works by penetrating the hair shaft and dissolving the melanin, which is the pigment responsible for hair color. On the other hand, developer is a chemical that helps to activate the bleach or hair color, allowing it to penetrate the hair shaft more effectively.
The main difference between bleach and developer lies in their function and application. Bleach is used to lift the hair color, while developer is used to enhance the effect of the bleach or hair color. Developer comes in different volumes, which determines the level of lift or deposit achieved. For example, a higher volume developer will result in a greater lift, while a lower volume developer will result in less lift. Understanding the difference between bleach and developer is crucial in achieving the desired hair color and minimizing damage to the hair.
Can using bleach and developer together cause damage to hair?
Using bleach and developer together can cause significant damage to hair if not done properly. The combination of these two chemicals can be harsh on the hair, leading to dryness, brittleness, and breakage.
