Normal, healthy hair and scalp have a natural balance that is disturbed every time you wash them. Did you know that normal shampoos contain chemicals (mostly sulfates, like sodium lauryl sulfate) that are identical to the ones found in detergents you clean your kitchen with? They completely strip your hair and scalp from its natural oils and destroy the balance. This makes you want to use conditioner and styling products – usually made with petrolatum and mineral oil – which act as a substitute for the oils you just rinsed out of your hair. But after washing, your body also starts making sebum (oil) like crazy to restore the natural balance. So what happens? Your hair will become very oily very fast again and within a day your scalp will be a great place for… the fungus causing dandruff to have a little party in.
