My hairdresser loves this line by Paul Mitchell and I decided to try it and I love it. She told me to rub it in my hands before applying it to my hair and then apply some on one side of the head and some on the other and then rub it all over so that way I don't have to use so much since it is so expensive and that technique works great. I have tried to do that same thing with my other shampoos but it doesn't spread as well or lather as much so it must be the lathering part of this that makes it so easy to use only a little and get a great clean wash from it. I love how it is gentle on my hair yet still gets it really clean and it smells nice. Even though it is a little pricey you don't have to use much so it seems to last a little longer than most shampoos. I was really afraid that I would like it when I finally tried it cause i know it is expensive and if I knew if I really liked it I would have to have some in my bathroom at all times so of course I love it so now when I run out I am going to have to buy some more without telling my husband. It shouldn't cost so much if replace each product that runs out rather than trying to buy the whole set at once.
