Deep conditioning treatments are specifically designed to provide intense hydration and moisture to the hair. Natural oils are commonly included in these treatments due to their nourishing properties. Oils such as argan oil, coconut oil, and jojoba oil are known for penetrating the hair shaft and providing moisture at a deeper level than many other ingredients can achieve. This makes them highly effective in restoring shine, elasticity, and overall health to dry or damaged hair.

Chemical relaxers, on the other hand, are used to permanently alter the structure of the hair to achieve a straight appearance, making them unsuitable for moisture enhancement. Silicones may create a temporary barrier that adds shine and smoothness but do not offer the same deep moisture as natural oils. Sulfates are cleansing agents found in shampoos that can strip hair of its natural oils, leading to dryness. Therefore, natural oils stand out as the most appropriate ingredient for enhancing moisture in deep conditioning treatments.
