I absolutely LOVE my FHI Stylus.Love Love LOVE it.I have medium-to-long hair that is colored and highlighted. It is naturally very wavy/almost curly and will frizz when I don't go curly.But this little tool has completely solved my hair problems!!It is very easy to use - and be SURE to check out their WEB SITE for instructions.For example, I saw their video for using it to smooth your hair - basically you brush it slowly while holding it taut - and It comes out almost as good as the salon. To the point that girlfriends ask me if I got my hair done that day. If it fools other women, then you know it is a good tool.It is faster than the 1.5 barrel curling iron I use instead of a flat iron and it leaves my hair with volume unlike the flat iron. PLUS I find I can redo a different style the next day. If I do straight today, I can do waves tomorrow and vice versa, which is harder with the other tools.I do my whole head in a few minutes and it looks quite good. You can smooth, make waves, add volume - u can also use it to make waves and other styles. I have done smoothing and waves and they both came out great.Highly recommended. Check their site, where you can see actual regular people do their own hair and see how good it works.Overall, an indispensable tool in my hair care arsenal!!!
