What does a hair oil treatment do and how does it work?

Hair oil treatments are used to nourish, hydrate, and strengthen the hair. They penetrate the hair shaft, helping reduce breakage, increase elasticity, and boost natural shine. Oils are rich in essential fatty acids and vitamins that help repair damaged cuticles and protect against environmental stress, heat tools, and chemical processing.

Depending on the formula, oil treatments can be used before shampoo (pre-wash), after towel drying, or even as an overnight deep-conditioning ritual. They're especially helpful for taming frizz, sealing split ends, and restoring softness to dry or dull hair.
