Each My Hairdresser Permanent Hair Colour is identified through the My Hairdresser Colour Number System. The Colour Number tells you everything you need to know about the Permanent Hair Colour. It describes the Colours Depth and Reflect.
How to understand the Colour Number
The first number of a Permanent Hair Colour will always be a Natural Hair Colour; it describes the Colour’s depth. The second and / or third numbers describe the Colour’s reflects. The reflects can be broken down in primary reflect and secondary reflect. The primary reflect will be the more dominant of the reflects. Reflects are the secondary Colour that is prominent in sunlight or with movement. They give your Colour character and dimension. Example: 5.53 Chocolate Brown has a lot of Red reflects to give you a full bodied Colour.
