I’ve tried almost every single flat iron under the sun! The worst ones from my experience are drug store ones, in the under $25 range. They don’t get hot at all! They don’t maintain a stable heated temperature, and don’t straighten my hair properly. They are also made with poor materials, leading to damaged hair.
I only ever saw best results using professional flat irons. They stay hot throughout the whole time while styling, and keep my hair looking lit. They are made with high quality materials such as Ceramic, Tourmaline and the list goes on! Materials infused with millions of frizz-smoothing negative ions, that really work! Thank god for good hair straighteners!
