My mother bought it without talking to me first. I believe she said that she found it helpful and that her crown (her thin area) had thickened up some. She wanted to return the products because she didn't think that the results were worth the price and when she called to get the return info, they told her the trial period was for 14 days and not 30 days as my mother thought. When she balked about paying $129, they reduced the price to $79.
