What are the consequences of using a shampoo for a different hair type?

It is important to use a shampoo that is adapted to your hair type. Shampoos for problem hair have very specific actions.

For example, a shampoo for dry hair will have lipid-replenishing action, that means it will replenish the oils in hair that lacks sebum.

However on normal hair, this may result in making the hair oily.

Conversely, shampoo for oily hair will generally absorb sebum or even reduce its production, which may dry out normal hair.
