I'm an Indian Oil fanatic, me and my daughter that is. We both use the amla oil,navratna,and the brahmi faithfully. I add amla into my daily leave in spray and it has worked wonders for both our hair. W e also add amla into our hair grease,just mix it well with a spoon. You can use it as a hot oil treatment before or after shampoos. We prefer to hot oil our scalps after the shampoo with brahmi. It heals hair conditions like sore scalp,dandruff, and promotes hair growth as well. Now for the navratna you have to be a bit more careful because it can overstimulate your scalp if you use too much. It has an effect like Vicks vapor rub. A little goes a long way with this oil. But, when you do massage some into your scalp its effects are exhilirating and relaxing. I know I once sprained my ankle really bad and warmed this oil up and rubbed my ankle daily. It not only relieved the pain but brought down the swelling as well. I can't choose between which one is the best because once you start to use these oils you will never give them up. Just my opinion.
