Found out from a book written by a beautician that the best thing to wash your hair with is soap! She said the reason most of us need to use conditioners is because of the shampoo we use – they strip hair of their natural oils. Her recommendation was to put soap scraps (or grated soap) in a mug to about quarter full, then add boiling water and stir to dissolve. This will produce a gooey soap which is great for washing hair, plus very economical too! I’ve used this for ages and find it works really well.
