Keywest Professional Silver Sand Developer 20 Volume 6% (1000ml)

A hair developer is a crucial component in hair colouring. It's an essential part of the colouring process, and with the developer, achieving the desired colour shade is possible.

The volume of developer to use depends on the desired color lift. For 1-2 lifts, use 20 volumes; for 3-4 lifts, opt for 30 volumes. For more than 4 lifts, go with 40 volumes. Choosing the right volume ensures optimal colour results.

A developer activates hair color by making it work effectively. It helps color penetrate the hair and change its natural shade. The strength of the developer decides how much the color can lighten the hair.

The strength of a hair color developer is determined by its volume. A 20-volume developer is less strong, a 30-volume developer is stronger, and a 40-volume developer is the strongest. The higher the volume, the more it can lighten hair.

The ideal ratio of developer to color for Keywest Silver Sand Developer is 1:1. For the best results, mix equal parts of color and developer.

The Keywest hair developer is made primarily of Hydrogen Peroxide, which helps the hair absorb new color by creating an oxidizing effect. It also contains Propylene Glycol to retain moisture, keeping hair hydrated and nourished. Additionally, it includes Pro Vitamin B5, which adds shine and luster, resulting in strong, shiny, and manageable hair.

No, the developer is not permanent in hair. It is used with hair color to help lift and change the shade. The developer's effect is permanent on the treated hair, but it doesn't affect new hair growth or hair where it wasn't applied. Its action is limited to the specific area where it was used.

Hair developer is used to lift the hair cuticle so it can absorb new color, making the color visible and vibrant. The level of lift depends on the developer's volume, which is chosen based on the desired color shade.
