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.
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.
20 volume is likely the most used developer in the salon. 20volume will give 1-2 levels of lift when used with permanent hair color. It is the standard developer for grey coverage, however, a stronger developer may be needed for more resistant hair types.
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).
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 10 Vol for tone down coloring and level-on-level coloring. Use 20 Vol if you are aiming for a 1-2 level lift (and if you have grey hair that needs covering). Use 30 Vol if you are aiming for a 2-3 level lift. Use 40 Vol if you are aiming for a 3 level lift and if the hair is particularly difficult to color.
If your hair is brown, you may need to bleach it more than once before you apply the grey dye. It's important you get your hair as light as possible before you attempt to turn it grey – this will help ensure a more even tone and vibrant, all-over colour.
Pigment loss occurs naturally in hair as we age. Along with the changes in pigmentation, grey hairs can also undergo structural changes Grey hair is often also coarser. The outer cuticle layer of greys can be more tightly packed and layered, making them resistant to colour absorption.
The typical ratio is 1 part hair color to 1.5 or 2 parts developer for effective gray coverage.

10 Volume (3%): Used for depositing colour without lifting the natural hair colour. This volume is suitable for toning or darkening. 20 Volume (6%): Provides moderate lift and is commonly used for covering grey hair or lightening natural hair colour by one to two shades.
For good grey coverage, we recommend 6% hydrogen peroxide. This is why at WECOLOUR this is the standard percentage that comes with your hair colour, unless you can choose the activator percentage yourself when ordering. If you do not have grey hair and only want one colour level lighter, you could also use 3%.
The standard developer for gray coverage is 20 Volume; however, 30 Volume and 40 Volume can also be used if the percentage of gray is low and additional lift is needed to achieve the desired result.
