Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Lanolin, a natural wax derived from the sebaceous glands of sheep, has been traditionally used in hair care for its emollient and moisturizing properties. Its use dates back centuries, particularly in folk remedies and early cosmetic formulations, where it was prized for its ability to soften and protect hair and scalp. Lanolin closely resembles human sebum, the natural oil produced by our skin and scalp, which makes it an effective barrier to prevent moisture loss.

While there is a long-standing tradition of using lanolin in shampoos, conditioners, and hair treatments to impart shine, reduce frizz, and improve manageability, the scientific literature supporting its direct impact on hair growth or strengthening is limited. Most studies and reviews focus on lanolin's efficacy as a skin moisturizer and protectant rather than as a hair growth stimulant or body system supporter. Its primary benefit appears to be in conditioning the hair shaft and scalp by reducing dryness and enhancing softness, rather than altering the health of the hair follicle or promoting new growth.

In summary, lanolin's use in supporting the hair body system is primarily based on traditional cosmetic applications rather than robust clinical evidence. Its main role is as a moisturizer and occlusive agent in hair care products, with evidence for deeper systemic effects or direct support of hair health being limited.
