BLOW DRYING NATURALLY CURLY HAIR STRAIGHT WITH GREASE

I came across this blow drying tutorial and was fascinated by the use of Blue Magic Castor Oil grease . I would never think to use grease to blow dry the hair. I always consider grease to be a heavy product, that will weight the hair down. It may have something to do with the amount of product you use. Like I always say, "results don't lie" and her hair turned out absolutely beautiful. Now I don't know how this would work on  kinkier hair, so I will first try and blow-dry my hair with a serum . Have you tried this method before?
