1. Coconut oil penetrates into the cortex (Journal of Cosmetic Science pg 169-184,2001).Why should you care? This oil can help condition, moisturise and strengthen your hair!
2. Coconut oil reduces damage to hair cuticle during combing especially wet combing that many naturals (not me) are fond of (Journal of Cosmetic Science pg 327-339,1999).
3. Coconut oil reduces swelling of the hair shaft when the hair is immersed into water, protecting the hair from hygral fatigue. (Journal of Cosmetic Science pg 169-184,2001)
I could have stopped at number 1, seriously how good is number 1?! This is not to say that coconut oil is the only oil you should have, but if you are going to have just one, then this is THE ONE.
