Most Helpful Positive Review BEST EVER!! I did not purchase this from Ulta, however, I would have if I would have realized it was available here sooner. This is hands down the best flat iron I've ever used. My hair is bleach blonde, fine, and tangles easily. This glides through my hair with ease. Not to mention how soft and shiny it left my hair. Great-great product!!
Most Helpful Critical Review Not worth the money I own the classic bio and love it so much. Got this one thinking it would be amazing with the plates but it's not as good as my old classic one

I would give this flat iron 10 stars if I could. I have used everything from hot tools to suratt and this is by far the best I have ever used. The first time I used it was on wash day. I used OGX Brazilian straight shampoo and conditioner. I had a wedding to go to the next day. I decided to forgo drying my hair and going straight to the flat iron (tends to make my hair easier to straighten) and tangle teaser for the "chase method". The usual tradeoff is that my hair ends up straight but dry, lifeless, and sometimes stiff. Not this time! My hair was straight, soft, shiny and had movement to it! Better yet, because it really seals the cuticle my hair held up for 7 hours through the humid outside wedding and reception. There was some puffiness by the end, but my hair didnt not even come close to fully reverting. Better yet, after washing it, I dont see any heat damage to my curl pattern from the iron. I am hooked! I purchased this half off, during Ulta Gorgeous Hair event, but if it broke, I would have to suck it up and pay full price. theres no going back to lesser flat irons.
Overrated! 2

I have tried and tried to love this item but I am taking it back. Way too much work!
Love it 5

I love it, my hair looks smoother and shinier when I used it! Don't let my hair frizzy and hard! Worth every dollar I just love it
Sorry, I cannot say one good thing about Bio ionic10x. 1
Disappointed from Texas
I don't understand the good reviews this iron has been given. It does not glide down your hair, it snags and you have to make an effort pulling it down your hair. Leaves your haír opaque and lifeless. 10 minutes after I use it my haír is wavy and frizzed again. It's the worst and most expensive iron I have used. I used to have a less expensive iron but it did a much better job leaving my hair silkier and healthier. I don't understand the high price. Had I known, I wouldn't have bought it even for $1. Sorry, I cannot say one good thing about Bio Ionic 10X. My hair is better off without it.
Amazing iron! 5
Katelyn from Milwaukee, WI
I don't write reviews for anything - good or bad. But this iron is seriously amazing. I've been straightening my fine, but thick hair for more than 20 years (I'm 32 for reference) so I can safely say I've used quite a few straightening irons. I was a CHI loyalist for the last 10 years or so, but my last one died and I was tired of buying a new one every 3-5 years. The Bio Ionic was 50% off when I purchased and I figured why not try it? My hair is shiny, straight, and feels AMAZING. No flyaways or frizz either! I used Wella's heat protectant spray and I think this is the perfect combo! I will be recommending this iron to everyone I know! ❤️❤️❤️
Seriously the best one out there!! 5
Crystal from Oceanside
This hair straightener is amazing! The best one I've ever found in 25 years. I have thick wavy hair and this flat iron easily transforms my hair to shiny, straight, and gorgeous in just a few minutes!
I actually prefer this over GHD 5
Vegasbeauty from Las Vegas
I have the newest GHD and hate that I can't control the temperature. This I can, so I'll reduce the heat to use on my bangs and other areas. I turn the vibration off. I find that it's easy to use. Even though it's a little longer, it has a cool shape to it and I find it makes styling much easier. I am happy with my purchase.

Not was expected 1
Cynthia O from Mesquite
When you did your hair straight with this flat iron yes, you can feel smooth and shine but is going to look well just for a minutes it doesn't matter if you put any product before or not, my hair start to se terrible minutes after a do, a mean at the end of the day looks terrible, my ends of the hair looks cramped I hate that, so I'm
Going to return and come back to my nume.

Not so Impressed 1
Shal from Illinois
I have dry frizzy hair and I bought this cuz I was highly impressed when my hair stylist used it on my hair and was raving about it. My hair looked so sleek and shiny that I ended up buying it. However, I was very disappointed when I bought it and used it myself. Very disappointed cuz it was an expensive purchase and didn't meet my expectations.
Best out there 5
Flores0118 from Clifton New Jersey
I love this iron!! I have thick coarse hair and this works like magic! For those of u saying it leaves crimps in their hair it's because of the tension you pass it with. Cant hold it down aggressively any tool would do that. It helps my hair not be frizzy while straight and made it shiny without burning my ends!!
so worth it 5
mzrock from Arizona
I am a Native American with long, thick, coarse hair. OMG this hair straightener is amazing!! My hair is super straight, soft and shiney! So worth it! I would definitely suggest you buy this tool!
Best straightener ever!! 5
AmeeS from Alabama
I have spent a ton of money in straighteners. I decided, after seeing and reading reviews, to invest in a Bio Ionic 10X and I'm so happy I did. I have thin straight hair that is prone to frizzing in the Alabama humidity and this straightener tames the frizz and my hair stays straight all day. My daughter has thick, coarse and curly hair and she can straightener her hair with this straightener and it doesn't frizz and will also stay straight. Worth the investment! I haven't tried it for curling but I've heard it does great curling too! It also comes with a 5 year warranty if you register your iron!! If your own the fence, go for it!!
Long time straightener, best I've had 5
LC from New Orleans, LA
I've been straightening my hair for soo many years and I invested in this and it's the best one I've ever had. It heats up so fast and is amazing quality, doesn't tarnish or have bad/peely labels, is easy to use, and works fast (maybe not in 10 minutes flat but that's not really something any flat iron can do if you really want long-lasting straight, smooth hair all over and section and prep it properly- usually it takes about 20 for me). I really love it and I decided to write a review after some friends and I were going out- One of them had straightened her hair with her own iron and was upset at how it was frizzy, fluffy, and not smooth, so I turned mine on and told her to try it for a bit before we left. She did one section (not even prepped) and it was so noticeably smoother and shinier than the rest of her styled hair and all of us noticed it and were stunned. I knew I liked it better than other irons I'd owned before (like cheaper ones and higher end ones like Babyliss), but hadn't ever gotten to directly compare it until then! I think with the warranty and the quality, the price is worth it as it's lasted a long time and I expect it will continue to last and be covered by the warranty.
(To the people upset if it can't curl your hair perfectly... just buy a curling iron??)
Novice at flat irons, but I really like this one! 5
Deb from San Jose, CA
I'm new at using a flat iron for body and waves. I've tried two other flat irons and hated them, even though they were well known brands (BaByliss and Hot Tools) for different reasons. I was ready to give up and not try another flat iron and go back to curling irons, but while I was browsing curling irons I met a woman who I started chatting with. She was browsing the flat irons and couldn't find what she wanted. As we talked, she raved about the Bio Ionic 10X Pro and said she was buying one for her teenaged daughter so she would stop taking hers (the mother's). Ultimately, we found the Bio Ionic 10X Pro and she bought one. I kept thinking about it for 2 more days, then decided to try it. I'm no expert at it, that's for sure, but I was able to get a very nice style with my first attempt using the Bio Ionic 10X Pro.
Works amazing 5
Erin from CT
I have super thick and coarse hair, this was the best straightener I have ever bought. Always had chis before. Huge difference and worth the price and I was skeptical about the vibrating plates but they are amazing.
Works Great!!! 5
Divine Love from Escondido,CA
I have used many flat irons but haven't found one that has been ideal. However, this one comes pretty close to perfection. It's gives you a very smooth finish. I love the digital display Abe vibration. Yes, it is expensive but I have spent a lot of money on many name brand products. I never heard of this brand but decided to research for the BEST flat iron and was impressed with this one.
So far so good!!!
Best iron out there 5
Jenn from Ohio
I main reason I love this iron is bc of the tip. It has a pointed tip so you can get little hairs near your ears and it's easier to grab more precise areas. It gets super hot or just got enough to where your hair won't burn. I have fine 2a/b hair. I used to use a CHI iron until it burned out on me and one I used this for about a month, I noticed my hair was in much better shape. More smooth, less breakage.
Disappointed 1
AKmama1121 from Anchorage AK
Bought this deciding on high ratings and disappointed after I got it. Looks and feels expensive but not for my hair. At 325-350 it curls but falls flat before I could finish the other side of my hair even with product on. Btw, not a newbie on hair products so it should not be an issue. Tried 400 and same result yet it already fried my hair. My hair always ends up frizzy and dry looking.
I gave up trying my best to like the product, sent it back to Ulta. Not worth the price for me.
Best straightener ever, get it, you won't be let down! 5
Merissa from Cadwell Georgia
This gets rid of the frizz even in there Georgia heat
Worth It 5
Mrs. P from Alabama
I am so happy I invested in this straightener. I really like that I can control the temperature so that I can help prevent as much damage as possible with a heat tool. It straightens my hair beautifully. I have also managed to produce the best curls with a straightener that I have ever done. They even last longer than when I use my Drybar wand. I have seen some complaints of hair pulling, but I have not experienced any of that. I do wipe it down prior to each use to help with heat tool care. So far, I'm impressed and quite satisfied with this investment.
Love it. 5
JoJo from Green Bay, WI
Tend to use this for loose curls/waves. Absolutely love the digital temperature control, as these functions on my previous straighteners weren't digital; I couldn't be sure what temperature I was actually applying to my hair, which is scary to think about. With this control, I can more accurately use the temperature needed for my hair, and the recommendations are pretty spot on—allows me to style my hair effectively but not worry about excessively damaging my hair! Produces lovely styles.
