“During lockdown I have been lightening my darker blonde to 11vol blonde. As I have used different products in an attempt to achieve my desired colour I have patchy' colouring. Purple shampoos were ok lifting yellow' tones but the orange' tones were stubborn. Now I have discovered this shampoo it has vanished the orange from my hair. I use it weekly to maintain the colour. It would be too drying to use more frequently. Good shampoo, good price for professional shampoo too.”
