Answer first
Three common myths: oil is not the same as hydration; drinking water helps general health but will not fix a dry scalp alone; and washing regularly with a mild shampoo does not dry out most scalps. Gentle cleansing plus a light water-based hydrator works for many people.
Myth: oil moisturises
Oil seals the surface but does not add water. Humectants like hyaluronic acid attract water.
Myth: washing dries the scalp
A study on washing frequency found frequent washing was well tolerated by most people.
Questions
Is coconut oil good for my scalp?
