Panthenol is a penetrating moisturizer. It penetrates and builds a very thin layer of moisture along the surface of the hair to add shine, softness and pliability without added oils or greasiness. It binds the hair follicles and coats and seals in moisture which is great for dry hair or to prevent dry hair and scalp, also reduces split ends and increases the tensile strength of the hair. Some studies have also shown that it swells the hair shaft giving more volume to your hair.
The structure of silk helps to keep hair moistured, soft and free from tangles and prevent water loss. Also, it helps to condition the hair without weighing the fibres down, giving you supremely healthy and voluminous locks.
