This product is a complete waste of money. It smells great like all the s-factor products, i was advised to buy this by another hairdresser, i originally wanted to buy s factors smoothing lusterizer because my own hairdresser had used it on me once, but this hairdresser said it would be way too heavy for my hair so suggested i buy the leave in moisture spray instead - she was so wrong! the cap is annoying because it doesn't spray very well, sometimes loads will come out other time just a tiny amount so its hard to spread it evenly through your hair. Its also very easy to spray too much and end up with greasy hair, its not obvious how much you've put in your hair until your hair has dried. I haven't noticed a difference since I've been using it and normally with tigi products, especially s-factor i see a difference straight away. I normally find that tigi hair products are worth the money because they last ages, and are way above any other brand with the results you get, but with this particular product its definitely not worth it. Don't let this put you off buying other tigi s-factor products because i own three other products by them and they are amazing!
