Bumble and Bumble Heat Shield Blow Dry Accelerator 4.2 Oz

The Bumble and bumble Heat Shield Blow Dry Accelerator is a lightweight pre-styling mist engineered to dramatically cut blow-dry time while delivering multi-layered hair protection in a single spray. At the heart of the formula is the brand's proprietary Honey Protective Complex — a conditioning blend anchored by honey, Kukui seed oil, panthenol, and yeast extract that works to smooth the cuticle, improve elasticity, and fortify strands against breakage caused by daily heat styling. Dimethicone and the Hydrogenated Castor Oil/Sebacic Acid Copolymer create a flexible, heat-dissipating barrier across the hair shaft, while UV filters Butyl Methoxydibenzoylmethane and Ethylhexyl Methoxycinnamate shield hair from the cumulative drying effects of sun exposure. In consumer-sensory testing, 3 out of 5 users agreed the mist cut blow-dry time by 50% after just one use — meaning less time under the dryer translates directly to less cumulative heat damage over time. The result is hair that finishes smoother, shinier, and noticeably less frizzy, with a sensorial signature of blood orange citrus, wild orchid, and blonde wood. Completely color-safe and free from parabens, phthalates, mineral oil, and formaldehyde, this mist is ideal for all hair types and textures — fine to coarse, straight to curly — especially those prone to frizz, heat damage, or slow drying time. How to Use Spray generously onto damp, towel-dried hair before blow-drying. Use your fingers to lift and separate sections, misting thoroughly into the densest interior areas — the crown and back of the head typically take the longest to dry, so give those zones extra focus. Rough-dry with fingers and the dryer first to eliminate excess moisture, then switch to a round brush to perfect and polish the finish. Use each time you blow-dry for consistent time-saving and protective results.
