Yes, the Chi works wonders! The 150-180 is well worth the price for this tool. I have naturally straight hair, but now that I live in Houston where it's humid almost everyday, I have to use it for sleek frizz free hair. Matrix sleek line works well and has a fair price. I currently use Crede shampoo and conditioner---which works great as well. Make sure you use a finishing product --- I like using Kerestase Oleo Relax Serum. It's a very light oil to add shine and it's not greasy! But as with any serum, use it sparingly! The bottle is about $30 dollars, but it lasts me at 9 months if you don't slop it on----just use a little bit--- I have thick medium length golden brown hair---just a tad below the shoulders.
