How we built this chart

Each row comes from the model’s current US Amazon listing. We record a spec only when the listing states it, and we check every value against the listing text. Anything not stated is shown as n/s (not stated) instead of a guess. Several listings of the same model are merged into one row. The chart rebuilds automatically every week. If you spot a wrong number, tell us through the contact page.

What the specs mean

• Plate width (in): Plate width refers to the size of the straightening plates. Wider plates are better for long or thick hair, while narrower plates are ideal for short or fine hair.
• Plate material: Plate material affects heat distribution and hair protection. Common materials include ceramic, titanium, and tourmaline, each offering different benefits for hair health and styling efficiency.
• Max temp (°F): Max temperature indicates the highest heat setting the straightener can reach. Higher temperatures are suitable for thick or curly hair, while lower temperatures are better for fine or damaged hair.
• Heat settings (settings): Heat settings refer to the number of temperature options available. Multiple settings allow for more control, enabling you to choose the right heat for your specific hair type.
• Auto shut-off: Auto shut-off is a safety feature that turns off the straightener after a certain period of inactivity. This feature is important for preventing accidents and conserving energy.
• Dual voltage: Dual voltage means the straightener can operate on different electrical systems, making it suitable for international travel. If you travel frequently, look for this feature to avoid compatibility issues.
