This stuff will have my heart forever. I am not one to blowout my hair, ever. But I had to while I was in Italy because my flat iron would not work (different voltage issues). Between the blowout with a sub-par brush and the hotel dryer cutting out every 3 minutes, my hair was such a frizzy mess that I gave up halfway through my blowout. In a last ditch effort to look mildly presentable, I used this sealing serum and my hair looked so silky and smooth.
