The ultimate frizz fighter! Heat-activated technology wraps an invisible shield around each hair strand to help provide frizz resistance. Leaves a super-glossy, silky finish without weighing hair down. How do I use it: For best results, do not apply any other pre-styling products. Begin with clean, damp, detangled hair. Work in clean sections and spray generously from roots to ends. Comb through to evenly distribute. To activate and seal in the formula, blow dry thoroughly and finish with a flat iron or hot tool of your choice. From Drybar. Includes: 6.4-oz Liquid Glass Miracle Smoothing Sealant
