They are ideal if you want to enrich your natural colour, brighten dullness, or refresh previously coloured hair.

Depth The depth of a hair colour shade is determined by the amount of darkness in the colour. Deeper shades contain more pigment, and absorb more light, while lighter shades have diffused pigments which are more transparent and reflect more light.
Detanglers Detanglers modify the hair surface their and main job is to help get rid of knots by using pH as acidifiers, and/or by coating the hair with polymers as glossers.
Developer Developer is the oxidizing agent that allows the haircolor to do its job. Most permanent haircolour today uses hydrogen peroxide as a developer. The peroxide is the activator so that the color can penetrate. It also disperses the existing color and can lighten the hair’s color level depending on the strength of the peroxide formulation. The peroxide developer’s oxidizing potential is denoted as its ‘volume’. Most haircolour formulas today work with a 10, 20, 30, or 40 volume developer.
Double process This is a colour technique that is used to achieve dramatic colour changes, ie going from blonde to dark. You often need the second coat to fill or even out colour.
