Im trying this: Idont use shampoo. It's been over two months since I've used shampoo and my results have been out of this world. My hair has grown a ridiculous amount and is now the longest it's ever been. It also takes 4 days for it to even get SLIGHTLY greasy, where as before it would start getting greasy in less than 18 hours. I will NEVER go back to regular shampoo.
