What specific benefit does coconut oil offer when applied topically to hair strands, related to its molecular size and ability to penetrate the structure?
It helps reduce protein loss because its small fatty acid molecules can enter the hair shaft.
Coconut oil has established topical applications for hair conditioning that stem from the physical properties of its component fatty acids. Unlike some other oils which merely create an external coating on the hair strand, the molecular size of coconut oil's fatty acids allows them to penetrate into the hair shaft itself. Once inside, the oil acts to fill voids and bind moisture, which directly assists in preventing protein loss—a primary factor leading to hair dryness, brittleness, and breakage. This preventative action is especially beneficial for hair that is chemically treated (colored) or frequently subjected to high heat styling, as the oil offers a protective internal layer against cumulative structural damage.
