Share of reviewers who stated an outcome for straightening curly hair. Ranked by the lower bound of a 90% confidence interval, so a product needs both a good share and enough reports to rank high.

The 7 products ranked here carry 4,871 reviews at Ulta. We searched them for straightening curly hair and read the newest matching reviews, up to 40 per product and store, posted between Mar 2013 and Sep 2026.
A review counts only when the reviewer used the product themselves. We drop reviews written in exchange for a free product or a sweepstakes entry (0 on this page), and products that are no longer sold.
Ulta also shows reviews first posted on brands' own websites. They run much more positive than store reviews of the same products (across 19 products with both, 76% of brand-site reviewers said the product solved the problem, against 55% of Ulta shoppers), so we show them on product cards but never count them.
Because we searched for the problem, people who had it are overrepresented. Compare products with each other rather than reading a share as your own odds.
Skin type, skin tone and age splits use what reviewers chose on Sephora's review form (and age on Ulta's when given). We only show a split when enough reviewers fall on each side.
Amazon buttons appear only on products that most reviewers here say fix the problem (at least 60%, with enough reviews to trust it). Everything else gets no buy link.
An AI model labels each review against a fixed list of points, and we spot-check the labels before publishing. We publish counts, never the reviews themselves.

BaBylissPRO Porcelain Ceramic Straightening Iron (12 of 15) and Drybar Tress Press Straightening Iron (10 of 16) come last. The ranking weighs how many shoppers stated a result, so BaBylissPRO Nano Titanium Prima Styling Iron ranks below Conair XL Onyx Ceramic Flat Iron even though its share is higher, at 88% against 86%.
Mostly yes: 22 of 26 shoppers with curly hair said it straightened their hair smoothly. More shoppers stated a result for it than for any other iron here, and it ranks fifth.
Follow the heat settings and instructions that come with the iron. Use a heat protectant if you already use one. We count what shoppers said about results, not safety, so the maker's directions are the place to check how to use it.
BaBylissPRO Nano Titanium Digital Flat Iron and BaBylissPRO Porcelain Ceramic Straightening Iron are sold on Amazon by the brand or Amazon itself, and BaBylissPRO Nano Titanium Digital Flat Iron is both the leader and the best pick sold on Amazon. For BaBylissPRO Nano Titanium Ultra Thin Flat Iron, Conair XL Onyx Ceramic Flat Iron, BaBylissPRO Nano Titanium Prima Styling Iron and CHI Original Ceramic Hairstyling Iron, we could not confirm the exact Amazon listing, so their buttons search Amazon for them. Drybar Tress Press Straightening Iron has no buy link here, because too few shoppers reported a good result for us to recommend it.
