Replacement glue for your V-LIGHT Professional system This specially formulated adhesive ( Ethyl cyanoacrylate , sodium stearate and a photo-initiator) , activates and cures with the V-Light applicator machine. V-Light Application process: 1. Preparation:  A protective shield safeguards surrounding hair and eyes from both the light and adhesive. 2. Application:  A small bundle of single-strand hair extensions is meticulously added to the sectioned natural hair. 3. Blending: A comb is used to integrate the extension with the natural hair. 4. Adhesive Application: The adhesive is applied to the base of the hair. 5. Curing: The light cures the adhesive, a process repeated two to four times per section, with each curing cycle taking eight seconds. Once cured, the extensions blend seamlessly, mimicking natural free-flowing hair and offering unparalleled comfort and concealment.
