The colour gradually fades with each shampoo. A true semi-permanent colour only stains the hair cuticle with colour. It cannot penetrate inside the hair to physically change your hair colour permanently. Think of it in the same way as wrapping coloured cellophane around a light bulb; the light bulb itself doesn't change colour, it simply picks up the colour from the cellophane. Semi-permanent hair colour is suitable for anyone who may be reluctant for a permanent colour change. It is also an excellent choice for those who feel that their hair is dull or drab. Semi-permanent hair colour can deepen colour tones without altering the natural hair colour. There are several advantages to using a semi-permanent hair colour. First the hair colour is self-penetrating and you can do it by yourself. The colour is applied exactly the same each time and you do not need to retouch it. Your natural hair colour will return in about 6 - 8 shampoos. You can use semi-permanent colour to enhance the natural colour of your hair. They can be used to add golden or red highlights and to deepen the colour of the hair. It can be used to tone pre-lightened hair, refresh faded tints and to add colour to grey or white hair. People wanting to keep and/or enhance their grey hair can use semi-permanent hair colour. It is also excellent for very thin or damaged hair that has been permed or relaxed.
