Category: Beauty > Curling iron. Updated 2026-10-16. Based on 89 counted first-hand reports from Ulta and Sephora shopper reviews, Feb 2014 to Jun 2026.

**Question:** Which curling iron is good for long hair?

**Short answer:** Hot Tools 24K Gold Extended Barrel Curling Iron has the best record for long hair, with 18 of 20 shoppers saying it curled their hair and the curls held, though every record here rests on a modest group. We could not confirm the exact Amazon listing for the leader, whose button searches Amazon instead, so the best pick sold on Amazon is Drybar 3-Day Bender Curling Iron at 14 of 21, nearly level with Bio Ionic Long Barrel Curling Iron at 9 of 13. Each record counts just shoppers who said they have long hair.

**What stands out:** Reviews first posted on each maker's own site were more positive than the counted records for Bio Ionic Long Barrel Curling Iron and BaBylissPRO Nano Titanium Spring Curling Iron, at 5 of 5 and 6 of 6. We show those reviews but don't count them.

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 curling iron works for long hair?**

Hot Tools 24K Gold Extended Barrel Curling Iron has the best record (18 of 20), followed by Drybar 3-Day Bender Curling Iron (14 of 21) and Bio Ionic Long Barrel Curling Iron (9 of 13), close enough to each other to treat as a tie. BaBylissPRO Nano Titanium Spring Curling Iron comes last at 3 of 9.

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

The second number in each record is the group size. Groups run from 9 shoppers for BaBylissPRO Nano Titanium Spring Curling Iron to 21 for Drybar 3-Day Bender Curling Iron, and the leader, Hot Tools 24K Gold Extended Barrel Curling Iron, has 20. 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 curling irons are sold on Amazon?**

Drybar 3-Day Bender Curling Iron and Bio Ionic Long Barrel Curling Iron are sold on Amazon by the brand or Amazon itself. For the leader, Hot Tools 24K Gold Extended Barrel Curling Iron, we could not confirm the exact Amazon listing, so its button searches Amazon for it, which makes Drybar 3-Day Bender Curling Iron the best pick sold on Amazon. BaBylissPRO Nano Titanium Spring Curling 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 long hair said after using each iron, not a lab test, so follow the label directions.
