Using Homemade Dandruff Shampoo
Pour a small amount of the shampoo into your hand. Massage it into your scalp. You may find that this shampoo is a little thinner than commercial shampoos. This is due to the lack of chemicals that is contains. It also makes it easier to spread and massage into your scalp.
Leave for a few minutes and then wash as usual with shampoo and conditioner.
