Great Drying Power, But Curls Don’t Last
on August 9, 2026

[This review was collected as part of a promotion.] I really like how powerful the Shark FlexStyle IonCurl Air Styling & Drying System is. The speed and heat settings are very easy to adjust, and it can get surprisingly hot. For drying my hair, I usually stick to the first heat setting and the second speed setting. The third speed is almost too strong for my hair and can cause it to knot while drying. I have very thin hair, so it tangles pretty easily, but the upside is that this dryer gets my hair dry very quickly.
The curling feature was a little different for me because I normally use a regular curling wand. I really like that the air wraps my hair around the barrel for me, which makes curling feel much easier and means I don't have to worry about accidentally burning myself. However, I found it difficult to get the defined, tight curls that I usually prefer. The curls came out much looser, and they started to fall out pretty quickly as I moved on to other sections of my hair.
I also don't normally put any product in my hair before curling, so that could definitely be part of the reason the curls didn't hold as well. Overall, I really like the drying power and how easy the FlexStyle is to use, but I would probably still use my regular curling iron when I want tighter, longer-lasting curls.
I would recommend this to a friend!

Very good!

[This review was collected as part of a promotion.] I like this dryer a lot! There’s definitely a bit of a learning curve and it’s pretty big, so it may be more challenging for people with mobility issues. Overall, I like the heat and blower speed control and it gives good frizz control! I have medium thick, curly, frizzy long hair and it was dry and smooth very quickly!
I would recommend this to a friend!

Worth it

[This review was collected as part of a promotion.] I have thick, wavy hair, and I was really impressed with how well it dried my hair! Usually it takes my hair forever to dry with a normal hair dryer, but this cut my drying time in half. There is a bit of a learning curve with the different curling/straightening attachments, but once you get the hang of it, it’s really easy. I was impressed with how smooth my hair was, and I really loved the different barrel options. The only other thing I would want is a diffuser to come with the device. 10/10 would recommend.

Amazing product
on August 9, 2026
Posted by: Ferayarza
from Miami
Gender:Female
[This review was collected as part of a promotion.] I loved the bounce of the curls and how fast it gets done, I usually counted 20 seconds to get it done with my previous curler, not with this.
The drying speed is definitely a 10/10 and my favorite feature was the frizz control. No need for oil on roots after getting the little frizzy hairs on top, that gadget is amazing.
I put the curls to the test going outside to the Miami humidity and they lasted!
Once of the things Id highlight the most is the amount of shine it gives, my roots are very dry normally but after styling, the shine the ion curler leaves 100/10

Great for smoothing and frizz control

[This review was collected as part of a promotion.] I have used my IonCurl twice. Once for drying and frizz control/smoothing and the other for round brush curling. Both times it performed very well. The drying speed is very fast, though the hottest setting is almost too much to bear. I found the frizz control tool easy to use and very effective on my color-treated graying hair. The round brush tool did a great job giving my long bob nice finished, curled-under ends. Looking forward to trying the curling tools when I have more time to get ready.

Love it!

[This review was collected as part of a promotion.] Overall, a very good product. The air is very strong and allows for the hair to dry quicker. I have long wavy thin hair and the product works well with it. I really liked how when I was blowing it out, the brush attachment stayed on. I had issues with my past shark air wrap, so I was very pleased. I also loved the frizz control attachment. It worked and made my hair very sleek. When using the air wrap attachments I found the hair pull to be stronger which I liked. The curls that came out from them were very clean and it did not take much time at all to do . The only negative thing I would comment on would be how long the curls stayed in. I have thin hair so that is definitely a factor, but I even sprayed it with hair spray and they kind of fell instantly. Other than that, the product is very good and I will be using it a lot!

[This review was collected as part of a promotion.] Dry time was amazing and I have extremely long hair. The curls lasted a long time as well- I know if I add hair spray they would have stayed all day. I’m incredibly impressed by how quickly it took me to dry and style my hair. Highly recommend!!
