The absolute best spirits adhesive for hair replacement work. PPI Spirits Gel is a thickened version of our definitive Liquid Spirits. Originally developed and perfected for use on the 2012 Oscar winning film, Lincoln, PPI Spirits is a very strong, fast drying matted adhesive, suitable for all lace hair-goods, crepe hair, and human hair. It doesn't yellow the lace, create build-up or get crusty. This gelled version won't drip or run down your actors' face, as it stays where you put it. This product is cruelty-free and vegan approved.
