Your hair is like a plant — along with needing space to breathe in order to thrive, it also needs moisture, and lots of it. But as Eaddy notes, lots of people get stuck on this because they don't know the difference between hydrating the hair and moisturizing it.
"Hydrating the hair properly is the process of using lightweight humectants, natural proteins, amino acids, and critical vitamins that penetrate the hair fiber, infusing and improving the absorption of water and nutrients so that the hair can hold and ultimately retain moisture," she said. "Moisturizing the hair involves the process of using moisturizing creams and oils to coat the outer surface of the hair to seal the hair shaft."
