Biolage Colorlast Color-Protecting Shampoo

From the moment you colour your hair, it's like everything is out to get you - the sun, the pollution, even your good old haircare routine. Fret not - this shampoo is your knight-in-shining-bottle. Thanks to its low ph, it prevents fading while gently cleansing your hair. So go out in the sun stress-free & wash your hair as often as you'd like - because your vibrant tresses are here to stay! Start with a coin-sized amount for fine or short hair, adding a little more for longer or thicker hair. Apply to wet hair & work up a lather by massaging well into the scalp. Rinse thoroughly with water. For best results, use this shampoo alongside a colour-protecting conditioner & serum of your choice.
