Many cosmetic products including shampoo, heat protectants, hair drops, or hair masks contain oils. Humans produce natural hair oil called sebum from glands around each follicle. Other mammals produce similar oils such as lanolin. Similar to natural oils, artificial hair oils can decrease scalp dryness by forming hydrophobic films that decrease transepidermal water loss, reducing evaporation of water from the skin. Oils on the hair can reduce the absorption of water that damages hair strands through repeated hygral stress as the hair swells when wet, then shrinks as it dries. Oils also protect cuticle cells in the hair follicle and prevent the penetration of substances like surfactants. == Oil types ==
