This is a great book for high school students to use. They can put themselves on a schedule to complete each section. I believe this book will help my child do better on his ACT test.

I have very think coase hair and this product did nothing to my hair, since my hair is super long I used two kits. I followed the instructions and left the product in longer than the 25 minutes it recommends. No change in my hair. If anyone knows of a better product, please comment.

Was suckered into this by a pushy salesperson at a mall kiosk for the "discount" of 100$. I tried it at home for a party and it is absolute junk. I am NOT HAPPY with this product and I am going to attempt to return it immediately. I wish I had had the sense to immediately say NO and save myself the aggravation and loss of a "restocking fee". I don't even usually like to straighten or curl my hair that often, and from what I'm reading here, it won't last long enough to justify the 100$ purchase price and WILL damage hair even though I was assured that it won't.
