I received my hair straightener and yesterday I did my first keratin with the new hair straightener, it is just wonderful and magical, the result is really 2 times better than with my last hair straightener, although it is also professional and I thought it was good. It is a pleasure to work with your hair straightener, thank you so much for such a great product 🙏🙏🙏

Hair was not electrified at all and the shine was better and I smoothed my hair 2 times faster.
