How much shampoo should I use?
Size of my hand, I pour it on over my head ! No wonder why most people find professional shampoos expensive. Most of it is going down the sink!
The ideal amount you should use is the size of a 10p piece. Before you apply the product, rub your hands together so it covers most of your hands. This will make the product cover all of your hair.
The main area you need to clean is your scalp. Once you lather and rinse, the rest of your hair will be cleaned too.
