When it comes to lightening or dyeing dark hair, understanding how developers work is crucial. One common choice is 20 volume developer, but many wonder if it’s strong enough for dark hair. Let’s break down what happens when you use a 20 volume developer on dark hair and how to use it safely and effectively.
If you’re planning to use a 20 volume developer on dark hair, here’s everything you need to know about how it works, what results to expect, and essential safety tips.
What Is a 20 Volume Developer?
A 20 volume developer contains 6% hydrogen peroxide and is commonly used for:
- Lightening natural hair by 1-2 levels.
- Depositing permanent color.
- Covering gray hair.
- Opening the hair cuticle for better color penetration.
Will 20 Volume Developer Lighten Dark Hair?
Yes, but with limitations.
- Light Brown to Medium Brown Hair: 20 volume developer can lift 1-2 levels, resulting in a slightly lighter brown or dark blonde base.
- Dark Brown to Black Hair: Results will be subtle. It may lighten hair just enough for a noticeable difference but won’t achieve blonde shades without bleach.
For more dramatic lightening (3+ levels), 30 or 40 volume developers or bleaching agents are needed.
