RUN TO BUY THIS! This is the absolute best hair product I have ever used. It feels like I just left the salon after I put it in my hair. I straighten my hair every day, and it usually has so many flyaways after, but this eliminated all flyaways without making my hair feel greasy or weighed down. This product is magical. It was gifted by Dyson in exchange for an honest review.
