Question: what is the difference between hydrating and moisturizing hair?
Answer: Moisturizing hair creates a barrier around the hair so that water does not leach out. ... Moisturizers can be water-based or oil-based. But the amount of water used in its creation is not as high as in a hydrating product. So when moisturizers hydrate hair, they moisten/ dampen the hair, and the oil can seal it in.
