Gently cleanses hair while neutralising yellow/brassy tones in blonde and white hair leaving it with a beautiful platinum sheen. It also enhances the salt & pepper look in men while combating dullness. This charcoal coloured toning shampoo distinguishes itself from the rest by being dual purposed. When leaving it on for 3 – 5 minutes after lathering, instead of rinsing immediately it maintains and intensifies grey tones. Whichever way you choose to use it, Pro-S Shampoo will keep your silver strands sparkling. What's in the box 1 x 250ml Shampoo
