Use a Colour-Safe Shampoo and Conditioner Now more than ever, it's important to use colour-safe hair-care products to keep your dye job protected. There are so many colour-safe products to choose from and the packaging will clearly state they're safe to be used on colour-treated hair. Some of our favourites include L'Oréal Paris Elvive Colour Protect Shampoo (£5) and Conditioner (£5) and L'Oréal Paris Colour Protect Anti-Brassiness Purple Shampoo (£5.50), made specifically for blondes. We also love the Kevin Murphy Angel.Wash (£22) and Pureology Hydrate Colour Care Shampoo (£14). Image Source: boots.com
