They have 2 brands. One is Davines and it's from Italy. It's prices are close too Purology. This product costs a bit more but the benefits are Awesome. I've been using it for a year now. Google the name and you can find it for less sometimes. The other hair product is real popular too. I'm sorry I can't remember the name. Give them a call. I'm sure they'd be more than Happy to answer your questions.
Not sure what the product is, but it is a little pricey, but is amazing to the hair.
