This is a new product, so I am not sure why the only two reviews have to do with price rather than the product. I had my hair done today and my stylist used this on me since she already uses 1 and 2 when she does my color and I use 3, 4, and 5 at home. Like all of the other olaplex products, this one did not disappoint. It left my hair soft and bouncy after blow drying. I love this whole line of hair care products. I always pay extra at the salon to have steps 1 and 2 done with my color. My hair is so healthy. I am going to purchase 6 as well.
