SAME AS REGULAR GHOST BOND except that this series has better resistance from wet/water Ghost Bond XL was specially formulated by Professional Hair Labs. With new improved features which include, extra moisture protection and a higher melting point, you can have peace of mind and confidence that your bonding adhesive will hold up to the most intense climates. formulated under the auspices of a team of chemists who develop surgical adhesives. Professional Hair Labs always puts safety first. Ghost Bond contains no latex, no harsh solvents, or any of the irritants frequently found in cheaper formulations. It has been specially formulated for oily scalps, high humidity, and heavy perspiration. Ideal for attaching your lace or skin system to your head. All you do is apply to the tip of your finger or use a small brush and then apply it on your skin and allow to dry clear taking about 3 to 5 minutes and then apply2 to 3 more thin layers to the scalp area let dry till adhesive is clear. Now attach the hair system to your head. Once you attach your hair system, you will need to rub the area to create a strong bond. I like to use the back end of my hairbrush and rub it back and forth to create a strong seal/bond. You can clean your finger or brush using just water & soap. Remove your wig using just about any adhesive solvent. I prefer to use 99.0% Medical Alcohol. In my personal experience with both my clients and on myself, I get about 3 days of hold time. Sometimes less. If you need a longer holding product that works like this white adhesive, try the new product just released --GREAT WHITE adhesive. This adhesive works the same with the exception that it has a much more powerful hold. I personally get 12 days' to hold time with easy clean-up.
