Not all oils are created equal when it comes to your hair!
Certain oils like coconut, olive, avocado, & palm (straight-chain glycerides) easily penetrate into the hair cuticle to help make hair stronger, more flexible, waterproof, and better conditioned; reducing the loss of protein! Studies have shown that coconut oil can penetrate up to 90%, followed by olive oil at 25%.
Other oils such as meadowfoam, sunflower, & jojoba (polyunsaturated fats) are larger in formation making it harder for them to penetrate the layers of the cuticles. Meadowfoam penetrates a little; sunflower & jojoba not at all.
