Overview
A wave heater and ionic technology drive the Drybar Buttercup, spreading heat evenly while ions help seal the hair cuticle. Separate heat and power controls plus concentrator nozzles let you aim the airflow while smoothing each section.
Even heat and ionic frizz control are the reasons to choose the Buttercup for a sleek, shiny finish at home. The listing skips hard numbers like wattage, weight and cord length, so drying speed claims are hard to judge before buying.
Who it's for
Suited to home styling where smooth, shiny results matter more than raw speed figures. Shoppers who want to compare wattage, weight or attachments like a diffuser will not find those details here.
Pros and cons
- Ionic technology targets frizz
- Wave heater spreads heat evenly
- Separate heat and power controls

- Wattage, weight and cord length not listed
- No diffuser among the included attachments
Performance notes
Drying speed comes from how evenly the wave heater spreads warmth across the airflow, so fewer hot spots means less time per section. Ionic output helps flatten the cuticle, which is where the shine and frizz reduction come from. The concentrator nozzles narrow the airstream so a section dries smooth against the brush instead of being blown around.
