I have been using their shampoo, conditioner, leave-in, and overnight treatment for about a month now. While it has not necessarily been the miracle product that I have been searching for, it does work well.
I right away noticed that my hair seemed smoother and slightly more manageable. It seems softer and I am losing less in the shower. However, after a few weeks, I either got used to the product, or it stopped working as well.
As for the steep price, get the trial for $5 shipping like I did. Before the 30 days are up, you may send back all of the bottles, even if they are empty, along with a code from the website. I called to inquire about all the logistics since I didn't want to go through all of that and still be charged $98 (yikes!) for messing up on one little thing. Customer service was very helpful and let me keep the products for a one-time charge of $40. I think that is fairly reasonable for 4 high quality hair products.
Give it a try!
