How to Bleach Hair
When it comes to bleaching hair, it’s important to understand the role that developers play. Developers are the oxidizing agents in bleach that help break down the natural pigments in your hair. Different strengths of developers can have varying effects on the final result of the bleach, which is why caution is required when mixing them with bleach.
Developers come in different strengths, including 5 volume, 10 volume, 20 volume, 30 volume, and 40 volume. The higher the volume, the stronger the developer and the more lightening power it has. However, with greater strength comes greater risk of hair damage and breakage.
What is a developer?
When mixing bleach with a developer, it’s important to choose the right strength for your hair type and desired result. For example, a 10 volume developer is best for slight colour changes and 5 volume for toning, while a 30 or 40 volume developer is needed for significant lightening.
Using a stronger developer than necessary can result in significant hair damage, as the bleach will strip the hair of its natural oils and moisture. This can lead to dryness, brittleness, and breakage. On the other hand, using a weaker developer may not achieve the desired level of lightening.
