Vegetal (semi permanent colour) is intended for highlighting the natural colour. Vegetal does not lighten the hair, nor is it intended to cover grey. It washes out after approximately 6 shampoos. To obtain highlights, choose a colour in the Golden, Copper or Mahogany series that is lighter than your natural colour. To obtain a deeper colour, choose one shade darker than your natural colour. You can also simply choose the same shade as your natural colour. Vegetal should not be used on previously tinted hair. It is intended to colour natural hair only.
