Your Hair System is a product that in the first application adapts exactly to the point where there is thinning and then cuts as desired. Even when you return the Hair System, it cannot be applied to another customer. We're basically throwing it away.
However, with our money back guarantee, we just want to relieve you of the worry that if the Hair System doesn't work for you, you'll be wasting your money. So within 7 days you will know if it works for you or not and if it doesn't, you get your money back.
