Hot fusion hair extensions was one of the original and most commonly used methods prior to cold fusion. With hot fusion, strands of hair are attached to your head with a keratin-based tip using heat to fuse the keratin bond and extension. Women prefer this technique because it adds length in a short period of time, allows for a variety of hair styles, and they are unnoticeable. This method is safe, comfortable and long-lasting.
Hot fusion hair extensions are attached to your own natural hair by heating a keratin-based adhesive with a hot fusion tool.
The extensions are applied strand-by-strand, allowing the hair to look more natural and to move freely. Heat from the bond may cause some stress to your own hair.
Takes about 2 hours to install and lasts anywhere from 2-3 months. A solvent must be used to loosen and remove the extensions, and they cannot be reused.
