**Question:** Which flat iron is good for wavy hair?

**Short answer:** Conair XL Onyx Ceramic Flat Iron has the best record for wavy hair, with 20 of 22 shoppers saying it straightened their waves smoothly in few passes. We could not confirm the exact Amazon listing for the leader or the next two irons, whose buttons search Amazon instead, so the best pick sold on Amazon is BaBylissPRO Porcelain Ceramic Straightening Iron at 12 of 16. Each record counts just shoppers who said they have wavy hair.

**What stands out:** The three BaBylissPRO irons here sit at different shares: BaBylissPRO Nano Titanium Ultra Thin Flat Iron is at 80%, BaBylissPRO Porcelain Ceramic Straightening Iron at 75% and BaBylissPRO Nano Titanium Prima Styling Iron at 58%. Check the exact model, not just the brand.

Ranked by the lower bound of a 90% Wilson confidence interval, so a product needs a high share and enough reports to rank high. An Amazon link is shown only when at least 60% say it works.

## Questions

**Which flat iron works for wavy hair?**

Conair XL Onyx Ceramic Flat Iron has the best record (20 of 22), followed by CHI Original Ceramic Hairstyling Iron (20 of 25), BaBylissPRO Nano Titanium Ultra Thin Flat Iron (16 of 20) and BaBylissPRO Porcelain Ceramic Straightening Iron (12 of 16). BaBylissPRO Nano Titanium Prima Styling Iron comes last at 14 of 24. CHI Original Ceramic Hairstyling Iron and BaBylissPRO Nano Titanium Ultra Thin Flat Iron share the same 80%, so treat them as a tie.

**How many shoppers are behind each record?**

The second number in each record is the group size. Groups run from 16 shoppers for BaBylissPRO Porcelain Ceramic Straightening Iron to 25 for CHI Original Ceramic Hairstyling Iron, and the leader, Conair XL Onyx Ceramic Flat Iron, has 22. Group size is already built into the order, so a card's rank reflects both its share and how many shoppers stated a result.

**Which of these flat irons are sold on Amazon?**

BaBylissPRO Porcelain Ceramic Straightening Iron is sold on Amazon by the brand or Amazon itself. We could not confirm the exact Amazon listings for Conair XL Onyx Ceramic Flat Iron, CHI Original Ceramic Hairstyling Iron and BaBylissPRO Nano Titanium Ultra Thin Flat Iron, so their buttons search Amazon for them, which makes BaBylissPRO Porcelain Ceramic Straightening Iron the best pick sold on Amazon. BaBylissPRO Nano Titanium Prima Styling Iron has no buy link here, because too few shoppers reported a good result for us to recommend it.

**Are these results from a lab test?**

No. The counts are what shoppers with wavy hair said after using each iron, not a lab test, so follow the label directions.
