Rating (out of 5): 3

Synopsis: Lipids, particularly certain essential fatty acids (like omega-3 and omega-6), have scientific backing for their role in supporting hair health and potentially reducing hair loss or thinning. Hair follicles are highly active structures, and their growth and maintenance require a constant supply of nutrients, including lipids. Deficiencies in essential fatty acids can lead to hair changes, including loss and thinning. Several studies have shown that supplementation with marine-derived omega-3, omega-6 fatty acids, and antioxidants can improve hair density and reduce telogen effluvium (a form of temporary hair loss). For example, a 2015 randomized controlled trial published in the Journal of Cosmetic Dermatology demonstrated increased hair density and reduced hair loss in women who took a supplement containing omega-3 and omega-6 fatty acids along with antioxidants over six months.

Topical lipid-based treatments, such as those containing ceramides or phospholipids, are also used to improve scalp health and hair shaft integrity, though evidence for their effects on hair regrowth is less robust. While not a cure for all forms of hair loss, the scientific evidence supports the role of certain dietary and topical lipids in maintaining hair health and potentially mitigating some types of hair thinning, especially those related to nutritional deficiencies or scalp barrier dysfunction.
