Nº.4P Blonde Enhancer™ Toning Shampoo
Purple toning shampoo to neutralise brassiness in blonde curls
Our Take
A purple-pigmented sulphate-free shampoo that neutralises yellow and brassy tones in blonde, bleached, or grey hair. Works like any toning shampoo — the violet pigment counteracts unwanted warmth. Contains silicones, so not suitable for a strict CGM routine. Use once or twice a week in place of your regular shampoo, not daily, as the pigment can over-tone if overused.
