“From using heat tools and coloring treatments to things like pollution and extreme weather, your hair goes through a lot. These things can leach moisture and protein from your hair, making it dry, dull, and susceptible to breaking, splitting and excessive shedding,” says Shapiro.
“Fortunately, coconut oil can help on every front, which is why it’s often seen in your haircare products and home routines. This is because coconut oil contains lauric acid, a fatty acid that, unlike other fatty acids, can penetrate deep into the hair shaft. As a result, it can help protect hair against protein loss while providing long-lasting moisture. This makes your hair look fuller, shinier and healthier. It also gives your hair a softer, smoother quality that’s easy to style,” he adds.
Maiman agrees, adding that: "Like mineral oil and many vegetable oils, coconut oil is effective at maintaining moisture within a hair fiber. This is because coconut oil coats the hair shaft on the outside, which provides a hydrophobic barrier that locks in moisture. Consequently, this effect slows the rate of moisture loss out of the hair shaft over time, similar to what some conventional conditioning products may do for you."
