This product is amazing. I love it! I had a really bad experience with a chemical straightening treatment (Japanese straightening) and my hair was so fried and damaged I had to cut most of it off. My hairdresser recommended this to me (along with the Shampoo and Conditioner) and I have been using them for the past 2 weeks....these products have literally saved my hair. Before, I couldn't even blow dry my hair, if I did, It would turn very brittle and dry and was completely unmanageable. I have quite fine, straight hair, so when I found this product I thanked my lucky stars. If it can work for my very damaged, dry brittle hair, it will definitely work for someone with less hair issues. It is quite expensive, but I think of it as 'you cannot put a price on beautiful, healthy hair", and you only need to use a little bit. The smell is amazing (I find myself opening the bottle from time to time just to smell it, wierd I know) but its so amazing. Its not too heavy for my hair, and it makes it absolutely shiny. My hair is still a little bit dry and damaged, but that is to be expected from such a traumatic experience I went through. It is such an amazing product I am hooked for life. it also, for some reason, makes my hair dry really quickly after I get out of the shower (which is amazing because my hair usually takes HOURS to air-dry) so it does make hairstyling more convenient. Buy it! You will not regret it!
