How Much Does It Cost to Run a Hair Straightener? (2026)
Flat irons and curling irons heat quickly to a set temperature and then cycle, so they average only 30 to 150 watts in use. Their cost is negligible.
A typical hair straightener (60 W) costs $0.011 per hour, or about $0.081 per month at 0.25 hours a day in United States (average). Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (30 W) | $0.005 | $0.001 | $0.040 | $0.49 |
| Typical (60 W) | $0.011 | $0.003 | $0.081 | $0.99 |
| High (150 W) | $0.027 | $0.007 | $0.20 | $2.46 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 0.25 h/day ≈ 5 kWh per year.

How to lower the cost of running a hair straightener
- Turn it off as soon as you finish. Leaving it on is the only meaningful cost, and a fire risk.
- Use the lowest temperature that works for your hair.
- Straighten dry hair. Damp hair takes longer and damages more.
