Can I Use My Hair Straightener (Flat Iron) in Brazil?

Check your device label first

Check your label first.

We can't confirm this is safe until you read your device's label. Plugging in the wrong voltage can damage the device or cause a fire. Find the printed input rating — usually on the device, its plug, or its power brick — and look at the voltage range: • If it shows 100–240V (or "100-240V~"), it's dual-voltage and safe on voltage worldwide; you may still need a plug adapter. • If it shows a single range like 120V or 220–240V only, it is NOT dual-voltage. Do not plug it into a different voltage without a suitable converter. When in doubt, do not plug in.

Based on a typical single-voltage US model — confirm your device's label to be sure.

The short answer

A US 120V single-voltage straightener on 230V power overheats and can scorch hair or fail. Confirm "100–240V" on the plate, or carry a dual-voltage travel model. Frequency does not affect heating.

Brazil runs 127V at 60Hz. CRITICAL EDGE CASE: Brazil has no single national voltage. Most of the south and southeast (São Paulo, Rio de Janeiro) is 127V, while much of the northeast and the capital Brasília is 220V — and both can even coexist on the same street. Always confirm the voltage of your specific city or hotel before plugging in. The frequency is 60Hz nationwide. Brazil uses the Type N plug (its own standard), which also accepts Type C.
