Straightens my hair. Gives me shine and smoothness. Freaking great quality, I have had mine for over 5 years and it works just as well as it did on day one. Only negative is the lack of volume but that's not its job, its not its fault it straightens so well my hair flat but it does bother me a bit.
Very fragrant but fades nicely. My hair does feel noticeably softer when I use it. Also calms down the frizz associated with my damaged locks. Very expensive but if you don't mind the cost, it does last quite awhile.
