My problems with my fringe continue to upset and offend so I thought I'd give this a try. As you can see, it comes in a box so I did not read the teeny tiny print on the back of the bottle before purchasing. If I had, I would have found out one thing and failed to find out a second. The thing you are told is that to keep your hair straight for three days as promised by this product, you have to use flat irons every day. Not every third day, Every day. If I want to do that, I don't need this product do I? The thing you aren't told is that it doesn't work without also using serum. Without serum it keeps hair straight about 30 minutes maximum. And if I use serum, I don't need this product, do I? And with serum and straighteners, you get about 3 hours of straightness out of it. Pointless waste of money.
