I don't seal with JBCO
I seal with jojoba or apricot. Lately more with apricot. Apricot is light.
I use Jamaican Black castor oil on my scalp. I dilute it with some coconut oil because JBCO is so thick. I use coconut oil with it because it can penetrate the hair shaft and my hair likes it. Also, it's less greasy than olive oil.
I apply it everyday before I go to bed. I massage my scalp with it (massaging your scalp may also stimulate hair growth).
