Fragrance Direct has joined forces with Crewe Hair and Skin Clinic to create an interactive tool to recommend how to navigate your hair washing routine.
While the south and east of England have the hardest water, we, in Scotland, are lucky to have soft water flowing through our taps.
Even though the calculator is based on the water hardness in your area, it also offers good tips on the types of shampoos and conditioners you should you use.
For example, if you have curly, coloured hair, it is suggested you use shampoos with ingredients such as betaines, sultaines and imidazolinium because they are especially good for dry or damaged colour-treated hair.
