Shampoo you buy from a supermarket or that is off the shelf not recommended by your stylist, is not always the right one for your hair type. For example, you may think you need highly moisturising shampoo but if your hair is fine this is the worst shampoo for you as it weighs your hair down and can make your hair stretchy. Also, supermarket shampoos are of high in inferior ingredients that can react with your colour application or even fade your newly applied service.
