Every night, I massage my Extra Virgin Coconut oil (EVCO) mix into my edges and around my hair line. The mix is about 1.5 tbs of EVCO, and 3 drops of peppermint, rosemary and tea tree essential oils.
I do not believe that this brings about any significant or accelerated growth but I know moisturizing my edges consistently has yielded great results like any other healthy hair care practice would.
During my hair care ignorant days, I used the curling iron daily on my edges and nape. Needless to say, this caused damage. Today, my edges are fuller and my hair line is not falling out or breaking.
Jamaican Black Castor oil and Jojoba oil are also excellent carrier oils to use along with your essential oils.
