20 volume developer is also a good option if you're looking to cover up some gray hair. It won't lighten your hair, but it will help to deepen the color and make it last longer.
20 Volume Developer: This is the most common choice for covering grey hair. It provides a little lift and is effective for achieving a more intense color. It's suitable for most grey coverage situations. 30 Volume Developer: This is used for more significant lift (usually one to two levels).
Grey needs at least a 10 volume and sometimes a 20 volume developer because grey hair is stubborn at opening up to accept color. It's coarser and the cuticle can be more tightly closed, making a 20vol necessary to open it more.
If you are trying to go darker or just deposit the color, a low-level developer like a 10 vol (or lower in some brands) would be used. If you are using a permanent, they usually use a higher developer like 20, to lift the hair and deposit color at the same time.

Hair dye volumes refer to the strength of the developer, which impacts the level of color lift. A 10 Volume developer provides minimal lift, perfect for depositing color. A 20 Volume developer lifts hair by 1-2 levels, while a 30 Volume developer lifts by 2-3 levels.
Use 20 Vol developer for most grey hair coverage situations.
Use 10 Volume if you are applying permanent, no-lift hair color. If the desired result is keeping color at the same color level by simply adding a tone or a tint, this is exactly what you should mix with. It won't significantly lift your base color and is the least damaging to the hair.

Pick a lighter hair colour
A lighter colour will then look better. Your hair follicles produce less pigment as you're turning older. If there's no more pigment being produced in the hair follicles, your hair turns pigmentless.

With grey the cuticle doesn't have pigment anymore so there's nothing the color can hold on to making them more resistant to color.

Always Use a 20 Volume Developer
Since there is no pigment, there is no need to lift. You just need to open the cuticle enough to deposit the color. If you feel you can get full coverage using a 10 or 15 volume then by all means use a lower volume.

We do not recommend 10 Volume Developer for covering grays as 20vol has a higher concentration of H2O2 (hydrogen peroxide) to open the cuticle more for lift and deposit.

If you're using semi-permanent or demi-permanent hair color, you'll need a developer with a lower volume, between 3 and 20 Vol. If you're using a permanent hair color, you'll need a developer with a higher volume. This is usually between 20 and 30 Vol.
