    Frequently Asked Questions

    1. How much product should I use for best results?
    Start with clean, damp hair by washing, conditioning, and towel drying. Spray Glass Hair liberally from roots to ends, then comb through for even distribution. Blow-dry in sections using a round or paddle brush, directing heat down the hair shaft to activate the primer and smooth the cuticles. Once dry, finish with a blast of cool air to lock in smoothness and shine. Style as desired, adding any finishing products if needed.
     2. What does it mean that Glass Hair is heat-activated?
