The Di Biase hot tool is a must have for hairstylists applying fusion hair extensions. Specifically created for Di Biase keratin bonds, our hot tool pliers work by melting the bonds just enough so that they are bendable into a flat position. This unique flat shape is what provides a seamless, virtually undetectable and comfortable bond. The shape and tip of the fliers provides a secure and comfortable application of the extension. No hair extensionists kit is complete without this hot tool!
