This volumizing spray is amazing! 
Thickening Spray is an aerosol rather than a foam, for easier application. 
It can be applied at the roots as a root lifter, or sprayed all throughout for additional thickness and body.  Even when liberally applied, this product does not get stiff or sticky.  Stylists can use this as a cutting lotion to build body as they cut.
To Use:  Spray at roots and/or all over damp hair before blow drying. 
To Touch Up Flat Dry Hair:  Spray on to dry roots and blow dry, lifting hair off the head as you dry.
