Different Types of Colouring

  • Daniel Galvin

Abstract

HAIR colouring products fall into three main categories:
  1. 1.

    Temporary. Artificial colour is applied to the hair and forms a loose connection with the outside layer, thereby producing a tone. This is easily washed off.

     
  2. 2.

    Semi-permanent. A greater resistance to water is achieved by using a fluid which suspends minute molecules of colour, resulting in deeper penetration of the cuticle layers. Thus semipermanent colours have greater durability than temporary colours.

     
  3. 3.

    Permanent. The artificial pigment penetrates right through the cuticle into the cortex where it becomes oxidised and integrates into the hair structure so that it is virtually permanent.
