Our lace wig mousse contains water, potassium sorbate. It is perfectly light, gentle on sensitive skin, and has a seamless tone. How to use it is simple: 1. This container is pressurized, so shaking it a few times before spraying will help the mousse maintain a light, fluffy appearance. 2 The foam will expand on your hands, so be careful and keep it light. 3. Apply lace tinting mousse evenly throughout the lace closure to color the entire lace. If the product is not completely distributed, you can always add more; 4. Once the coloring process is complete, it is recommended to blow dry the lace or air dry it for best results. If more time is needed, just use more products. Lace wig mousse perfectly fits the skin, dries quickly, paints easily, leaves no residue, and is safe and convenient.
