I just tried this for the first time a few days ago, has anyone else tried this and had success? I think it's a great way to wash hair!

What you're talking about is the CO method. In CWC (Condition, Wash, Condition), you first wet your hair with water, and apply conditioner on the length. You let the conditioner do it's work while you shower, and then before washing it out, you put shampoo on the scalp. Then you wash it all out, condition the length again, and wash it out. 

It really depends on your hair type. I found that the CWC worked really well for me, but sometimes too much conditioner makes your hair limp. Since my hair isn't straight, and it's dry sometimes, this really helps. Try it out and see how it works for you!
