Hi im new to this site. I have thick hair (due to genetics & good diet) but I have always used shampoo. I feel their is still room for improvement and shampoo makes my hair dry so I would like to go all natural. What is the best herbal powder that has been known to make hair grow thicker and longer? Is Shikakai powder good? Ive heard of this and want to buy it but im not sure which one is the real deal, I want to buy pure one.
