Philip Kingsley Pure Blonde Booster Mask
Application: after shampooing, gently work through the hair, avoiding the scalp. Leave for up to 3 minutes if hair is bleached, up to 5 minutes if hair is dyed, and up to 10 minutes if hair is naturally blonde. Rinse thoroughly. Use once per week. These timings are a guide only and should be halved for first use. All hair will react differently so test a small section of your lightest hair before first use. Wait at least two weeks after having hair coloured, bleached or permed before using
