Well I use half JBCO because I like the other oils too. Coconut oil is a natural protein and contains antioxidants and is completely absorbed through the hair shaft and aids in hair growth. Tea tree oil helps to soothe the scalp, aid in hair growth, an antiseptic, an anti-oxidant and antiviral agent. Jojoba oil is an oil that is close to the natural oil, sebum that your body produces and is a moisturizing oil. I just like the combination and my hair does too.
