I always see these two words used on products for skin and hair, yet despite looking for a solid answer I can’t seem to understand what the difference is or really what each does.

Generally moisturizing elements are fat based and hydrating elements are water-based…
But this is just the general expectation the buyer has when they purchase a product and it’s not an actual hard and fast definition.
Moisturizers tend to coat to the surface of your hair or your skin so your natural hydration is held in.
Hydrating moisturizers or hydrating body washes tends to actually introduce humectants that absorb moisture from the air to bring it next to your skin.
These aren’t definitions though these are just the ways things are generally described.
