http://www.folica.com/hair-care/hair-gel...iking-glue Note and to avoid confusion, yes this is a hair-gel as such, but if you look at and read the writing on the container it clearly say`s ` Spiking GLUE` ---- this is not a ` normal` hairsystem glue as such, and was not formulated or designed for holding hair systems in place----someone just happened to discover that it works effectively for that purpose......it will not give you a week`s hold...... it is affected by exposure to water and excessive sweating..... whilst it does give a good firm / solid hold over 90% of the system, it tends to lift a bit around the perimeter after a while [usually after a day, depending on certain factors] ...many guys use a bit of normal adhesive or tape at the front hairline to overcome that fact. It will release quite easily in the shower without the need of alcohols or solvents.....as has been pointed out, it can leave a white staining/residue on lace at times. It certainly has it`s ` place` in any wearers supplies cupboard, but you can not take part in activities such as swimming or it will de-bond. It`s great to use when going for a cut-in, as it sets in no time, thus saving a lot of ` hassle` with the stylist waiting for coats of glue to dry , and can simply be removed afterwards in the shower. It`s well-worth having a tube of it with you when travelling too......like any product in this game , it has it`s upsides and also it`s downsides.
