I have used several of the HairOne products and have enjoyed the results. I will tell you that after a year of co-washing (essentially washing with conditioner) It isn't necessary to spend this much on a conditioning cleanser as I have found that Suave, VO5, Pantene and other "cheaper" conditioners work just as well without breaking the bank.
I love Hair One. It leaves my hair feeling clean and light and gives it nice body. It took a little getting used to. I wasn't sure how it would work without all the foamy suds but after a few uses my hair is shinier and feels so much better, not weighed down like it used to with my other shampoo and conditioner.
