Synopsis

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

Squalene is a naturally occurring lipid found in human sebum, plants (such as olives), and shark liver oil. It is widely used in cosmetic formulations, including hair care products, primarily as an emollient and antioxidant. Scientific studies have demonstrated squalene’s ability to provide moisturizing and protective effects for the skin and hair. Its chemical structure enables it to form a barrier on the hair shaft, reducing moisture loss and increasing softness and manageability. Additionally, squalene has antioxidant properties that can help protect hair and scalp from oxidative stress caused by environmental factors such as pollution and UV radiation.

However, the direct evidence supporting squalene’s effectiveness specifically for promoting hair growth or treating hair loss is limited. Most research focuses on its general moisturizing and protective benefits rather than targeted therapeutic effects for hair conditions. The evidence primarily comes from in vitro studies, animal models, or extrapolation from its effects on skin barrier function. There is a lack of large-scale, high-quality clinical trials examining squalene's efficacy for hair health in humans.

In summary, the use of squalene in hair care is scientifically supported as a moisturizing and protective ingredient, but direct evidence for its use in treating specific hair conditions is modest. The overall evidence rating is 2, reflecting supportive but not robust clinical data.
