3 Ways to Cut Your Curling Iron Energy Bill
- 🌱
Use the auto-shutoff feature instead of manually remembering to unplug it — forgotten irons waste energy for hours.
- 💡
Preheat to the lowest effective temperature for your hair type — higher isn't always faster or better.
- ⚡
Curl multiple sections while the iron is hot rather than letting it idle between sections.
