The brush has special vents that allow air to flow so hair dries faster. Plus, it's quicker than using a dryer and then a flat iron or curling iron, which equals less heat damage.
Promising review: "My hair usually takes forever to dry and then I just pop in some hot curlers because I don't have the patience to smooth it out. Well...this product is nothing short of amazing! I regular dried my hair just a tiny bit with a normal hair dryer and then started with this product. When I finished, my hair was so smooth and shiny...I could not believe it. It hardly took any time, looked better than when I go to the salon, and it was super easy. I don't wash my hair every day and now all I have to do is get this thing out, and use it to smooth out my hair. It takes about three or four minutes when dry and I'm ready to go! I simply cannot believe how nice my hair looks. I had another brand and it burned out. This brand is SOOOOO much better. I LOVE LOVE LOVE this thing!!!!! Price is great and product is amazing!" —Lynn
Get it from Amazon for $34.88+ (available in seven colors). If you've tried barrel-shaped hot air brushes before without success and have tighter curls or coils, you may want to try the paddle brush version, which reviewers with 3A–4C hair swear by.
