Tri Aero Body Infusion – Spray-In Volumizer is best used for individuals who most needs body in their hair and could never use any other body building products… Everything was too heavy for fine and ultra-fine hair, until now! Tri Body Infusion goes on while the hair is still damp. You simply mist the product over the hair from about 12 inches away. As you begin to blow dry, the volume of hair doubles, but you can’t find the product in the hair. Tri Body Infusion came about from research for smaller and smaller resins to hold hair in place, similar to the resins used to add body to hair. The breakthrough occurred when we found a way to apply these resins to wet hair in an aerosol format. The aerosol application allows for the lightest layer of body enhancers imaginable.
