Detailed Product Description

Cold fusion is a new method for bonding hair extensions to one's hair. This method uses ultrasound waves and a keratin-based polymer to attach extensions to the root. Cold Fusion bonding uses ultrasound waves that are transformed into mechanical energy. The vibration caused by the ultrasound energy crystallizes the polymer, forming an invisible and long-lasting hold. Cold fusion has many advantages: * It is great for thin hair because it uses not heat. * The polymer offers more flexibility than hot-glue, thus resulting in more natural-feeling hair. * In contrast to the hot fusion method, which requires a hot fusion plier to melt the bond into the hair and thus will not allow for extension to be added near the scalp due to the heat, with cold fusion hair can be bonded very close to the scalp and even in front of the head.
