What oils can I mix with Shea butter oil for hair growth?

It's said that castor oil, vitamin E oil and almond oil help but massaging your scalp for 5 mins a day will help more because the oils are just to keep the scalp moist and they don't make major diferences it's more about genetics, keeping hair healthy. When you're washing the oil make sure you clean it off well you wouldn't want to go around with an oily head. Massage your scalp everyday, exercise (so blood goes to your head) or dance, eat healthly and balanced especially protein is important. So good luck :))
