Water Make-up works just like watercolour paint. The best way to apply Grimas Water Make-up (Pure) and Water Make-up Pearl Pure is to use a brush. Use the brush and a little water to soften the make-up and make it a bit pasty. Test the colour intensity on the hand.
Water Make-up works just like watercolour paint. Don't work too dry, but do not use too much water.
General tip: Water Make-up can be used to add (additional) colour to the hair and eyebrows, provided that the hair is not permed, bleached or dyed. Use a toothbrush to do this.
Hair that has been coloured using Water Make-up (Pure) can be washed with shampoo.
Water Make-up dries quickly, so you need to work quickly to achieve a beautiful result.
