- Long Barrel Curling Iron, Moisture Heat Technology & NanoIonic MX

I’ve tried a lot of curling irons over the years, and this is by far my favorite. I have thick, heavy hair and live in humid Florida, yet my curls actually last all day with this curling iron. The long barrel is my favorite feature. My hair isn’t especially long, but the extra length makes it so much easier to wrap my hair, create even curls, and avoid burning my fingers. I also appreciate the adjustable heat settings so I can choose the right temperature for my hair. It heats up quickly, is easy to use, and gives me beautiful, long-lasting curls every time. If you’re debating whether it’s worth the investment, it absolutely is. I only wish I had bought it sooner!

I absolutely love this curling iron! I have fine hair and I struggle finding a a curling iron that makes curls that actually hold. These curls seem to be staying in place and I love the long barrel. I’m able to curl my long hair all the way up to my scalp. For me this one is absolute winner. It is very easy to use, and easy to glide my hair through the clamp. I am definitely no pro at using a curling iron and I found this one very easy to use. Two thumbs up!

Oh boy, let me tell you about my adventure with the Bio Ionic Long Barrel Styler! As someone with hair that often seems to have a mind of its own, I was on the lookout for a miracle, and this styler came pretty close! First things first, this magical contraption's longer barrel had me feeling like I was wielding a wizard's wand. I've got Rapunzel-level locks, and this extended barrel was like the Excalibur of hairstyling tools, making it a breeze to tame even the most stubborn sections at the back of my head. Who knew styling the back could be this easy? It's like having eyes on the back of your head... but for your hair! Now, let's talk curls. This thing can whip up curls faster than a chef can flip pancakes. The NanoIonic MX infusion in the barrel felt like a potion straight out of a Harry Potter book, shaping curls quicker than you can say "wingardium leviosa." And the best part? The curls actually last! No disappearing acts or fading away into dullness—these curls stay hydrated, bouncy, and vibrant. The BioCeramic Heaters are like the unsung heroes, silently working their magic to ensure a consistent and even heat. No hot spots, no cold patches—just a perfectly heated wand ready to craft those fabulous curls. Let's not forget the protective cool tip. Not only did it save my fingers from accidental burns (trust me, I'm quite clumsy), but it also gave me a sense of hairstyling sophistication. Who knew a cool tip could make you feel like a pro? And the cord! A 9ft swivel cord, folks. I could dance around my bathroom while styling my hair if I wanted to (which I did, no judgment, it was fun!). Oh, and did I mention the universal voltage and 1-hour auto-shutoff feature? Perfect for jet setters and forgetful souls like myself. No more worries about accidentally leaving it on when rushing out the door! In conclusion, this styler isn't just a hairstyling tool; it's a sidekick, a trusted companion in the battle against bad hair days. So if you want a magical wand that turns hair troubles into stylish triumphs, the Bio Ionic Long Barrel Styler is your spellbinding solution! Five stars from this delighted hair wizard! Disclaimer: No magical creatures were harmed during the making of these curls.

I'll start by saying I really liked the performance of my Babyliss Pro I had been using since Aug 2024. The only reason I went back on the hunt for a new one is that the Babyliss does not have auto shut-off (as my prior few models had) and I was weary of getting to the end of my street and heading back home to be sure I turned it off. Reviews on the Bio Ionic were some of the best I had seen and it had every feature I sought: digital with multiple heat settings and auto shut-off. The longer barrel was but a bonus for my long hair that hits mid back. So, I was quite excited to try it out. The first thing I noticed and was quite disappointed by was that the built in stand didn't prevent the top several inches of the rod from resting on the counter surface. That certainly wasn't great, but I got massively frustrated the first time I used it because I kept unintentionally changing the temperature up or down as I tried to wind each curl. Changed the position of my hand and very intentionally attempted to NOT keep doing it to no avail. Ughhh. I was so annoyed. I was going to keep it a bit longer and try to find a method that didn't cause the buttons to move but also realized that the back parts of my hair weren't even getting a curl. I made sure that it was on the right temp (360) and that it had been on that setting for a good minute (you know, since the last time I accidentally changed it) and it still came out as straight as a sheet. My babyliss was still on the counter and I turned it on to my normal temp (355) and did the same section of hair with a perfect very loose curl. As a point of information, my stylist says my hair is "fine but I have a ton of it" I do use smaller sections in the front that I am trying to achieve a bit more of a curl than the back where I am just trying to smooth it and give it a bit it a wave and I have been successful in achieving that with Babyliss (3 models), Hot Tools (2 models), and Kristen Ess curling irons in that 360-ish range without any problem. Why this one couldn't do it I don't know, but between that, the stand not keeping the hot rod off the counter, and the inadvertent temp changes, it is sadly being returned. Glad others like it and I sure hope I can find my new favorite soon.

Worth the cost. Works great! My favorite curling iron. Not heavy. High heat.

This curling iron is WONDERFUL! Even at a low temperature, my curls stay. I feel like my hair is less damaged. If I forget to shut it off, it automatically turns off. The barrel is longer so the long-haired girlies are included! 10/10 would recommend!

I have very thick, wavy hair and have had the same curling iron for years. When it broke, I did quite a bit of research before picking this iron. I wanted a longer length iron because of my hair length and this one is perfect. It has a longer than average barrel. You can set the heat that you want and if you are like me and accidentally click the up or down heat setting while curling, this iron has a feature to lock it so that doesn’t happen. The only feature I don’t like is that the tip of the iron lays against the counter surface. I wish it were a bit elevated. I’m attaching a few pictures so you can see what I am referencing. In picture #1 this is how it lays. In picture #2 I am putting pressure on the back of the iron so you can see what I’d like.

I have been looking for a really good quality curling iron and I know the price point is really high on this iron but let me tell you it is fantastic. The curls stay in my hair for days. I am not disappointed in this product at all. I highly recommend if you are looking for a good quality curling iron it’s worth the investment.

If you’re looking for a curling iron that offers professional results without the ultra high price tag, this pro curling iron is a great option. While it’s a bit of an investment, it’s actually more affordable than many high end styling tools, and the results speak for themselves. I have long, thick hair and the 1.25 inch works great, leaves hair smooth and shiny. There’s no tugging or pulling, just a smooth glide that feels gentle on my hair. The design makes it easy to maneuver, and with a bit of practice and the help of a few tutorials, I’ve been able to perfect my waves. For best results, I found that taking time to get the technique down is key. Once you have that, the waves turn out beautifully, and they last all day with a light spritz of hairspray.

I love this curling iron. The extra long barrel is good for long hair especially for my extremely unmanageable hair. Also I was worried it would be too heavy but it's quite lightweight. And my favourite bonus is that you can lock the temperature so you don't accidentally turn it up or down while using it (which I tend to do a lot).

Love it, does the job. Quick to curl and lasts long enough. Perfect size curl as well.

Great quality. Professional grade.

I own and have used two other Bio Ionic heat styling tools for years (flat iron and curling wand both purchased from Sephora) and love them. So naturally, I purchased the bio ionic curling iron on Amazon thinking it would be the same quality. The first time I used it I had multiple issues: I could not get the clamp to hold my sectioned hair while my hair kept getting caught at the base of the barrel. There was a really bad burning smell (which lasted until my next wash) AND the curls fell out before I was even properly done styling. I wrote off all these warning signs as my own fault and that I just didn’t know how to use the curling iron correctly. There are even reviews here that say it takes some getting used to. I’ve since tried a handful of times, changing thermal protection products, using setting sprays, changing temperature settings and watching YouTube how to videos and am finally convinced this isn’t a user issue. I gave myself so long to “learn how to use it correctly” that I’m now outside the refund window and Amazon can do nothing for me but refer me directly to the company, who also have a disclaimer on their site that I have to apply for warranty coverage within 30 days of purchase. Next time I’ll be less quick to blame myself and just return the product. Don’t waste your money OR if you’re a Bio Ionic fan, make sure you figure it out within the refund window.
