If you’ve recently had a hair colour treatment of any kind, you probably want the colour to last as long as possible, while also keeping your hair healthy. The processes of dying, bleaching, highlighting, low lighting, removing colour and getting a chemical treatment can be stressful on hair, and remove a lot of the natural moisture your hair needs to continue being strong and healthy.
After colouring you might need to discontinue use of your current shampoos, conditioners and hair styling products, and purchase some that are specifically designed for colour or chemical treated hair. Using salon professional hair products are much more concentrated, than those you can get from the supermarkets, and generally last 3 times longer too.
Ask you stylist for advice during your next appointment.
