SMART-X High Efficiency Dryer + Diffuser

I love drying my hair with this dryer. Three heat and air flow speeds. No worries about accidentally hitting the cool button. Settings can be smart set. Lightweight and slim and will fill easily into a suitcase. Best part, it doesn't cause that scorching, over dry, frizzy look to my hair. Phenomenal!! My last Bio Ionic dryer last over 10 years. Bought a T3 during Covid and it's no comparison to this new Bio Ionic hair dryer. To me, it's worth the price!

I’ve now had this hair dryer for 6 months and I love it so much. I had splurged on the Dyson supersonic and the weight was all in the handle and felt uncomfortable for my wrists, so I gave it to my sister and got this one (luckily on sale!). Let me tell you, this Bio Ionic dryer is better than the Dyson. It is light as a feather and compact, so you could easily travel with it and my arms never get tired using it. And the power is incredible. It’s almost hard to believe how strong it is for how little it is. On full blast I actually have to be careful about where I point it because it’ll knock down my smaller makeup products sitting on the counter lol. BUT this dryer doesn’t tangle my hair in knots like the Dyson did. I have fine hairs but a lot of it, and when my hair was long it took about 6-7 minutes to give myself a blowout with a round brush. Now I have a bob and it takes less than 3-4 mins to dry and it doesn’t fry my hair. The amount of time saved and the silky, voluminous end result is just unmatched. Also it’s a game changer to not feel exhausted arms after blow drying. I would say this dryer is worth the full cost and if you’re concerned, add it to your wish list to get notified when it’s on sale (you might just have to wait a bit). Otherwise, treat yourself - you won’t regret it!!

[This review was collected as part of a promotion.] I absolutely love my SMART-X™ High Efficiency Dryer + Diffuser! It is unlike any I have ever owned before! It is made of quality materials and dries my hair very quickly and leaves my hair in better condition than other hair dryers have in the past! The BIO: IONIC warranty is also much better than any I have seen in the market! This is a new dimension of hair dryers from years past—and is well worth what you pay for it!

[This review was collected as part of a promotion.] This is the 3rd Smart-X High Efficiency Dryer I've owned. I originally purchased it because of style, color and light weight for travel purposes. I have medium thickness shoulder length hair that is kind of course. This dryer has the right amount of temperature and fan that it doesn't dry my hair out like other brands I tried such as the Shark. I do have to say it has a design flaw in the motor, which gives it usage life of 1 to 1.5 years. Unfortunately, I forgot to register the product and ended up having to rebuy my 2nd one. This time, I did complete the warrenty process. After one year from purchase, the same issue occured, the only thing that would work was the cold function. Apparently it's a design flaw in the motor and it's a safety issue that switches it to cool shot only. There is no turning off and letting it cool down, it just gets stuck in the cool function mode. I did submit a claim and was sent a brand new Smart X High Efficiency Dryer. I do have to place on calendar a note to purchase a back-up hair dryer, probably a different Bio Ionic one so that when mine stops working, I can send it in for warrenty claim. I wish the design flaw could be corrected as it's the perfect hairdryer for me, including how light it is for traveling.

[This review was collected as part of a promotion.] My hairdresser uses this brand. I bought for a lighter weight dryer for a senior citizen. Also my hair is getting coarse and brittle, this has helped.

I received my first dryer December 2025, i cleaned the filter about once a week, it got super loud and weak out of no where in April/may until it stopped working completely, i used my warranty and got a new one in June, i got my new one very fast after mailing out my broken one, i am a hair dresser and specialize in blowouts, so i made sure i was cleaning my new one every day I would do the self clean with a little brush and I would scrub the part that came off as needed, my new dryer got super loud again in September and 2 weeks later the heat stopped working completely, I loved this product but it did not hold up, this not durable for a stylist use. I would like to use my warranty and get a new one again but I have not had the time to mail it out and i no longer trust this product as a stylist I can’t worry about my hair dryer breaking If I decide or have the time to mail my broken product out I will be using it personally, not at the salon, disappointed because I did love this when it worked.

It doesn’t deserve even one star. Hairdryer broke within 4 months using it and 10 year warranty is a joke. I sent them blow dryer for my money and they just sent email that my warranty is denied. Please beware!!! My colleague sent hers 6 times and her last one broke again!

I've bought this dryer 3 times now. I love that its super light and comfortable to use BUT it doesn't last. Two died within a year. Its too expensive to have to replace it every year.

[This review was collected as part of a promotion.] Bio ionic was so quick to replace my dryer when I sent it in. I’m very pleased with them honoring their warranty.

My third dryer that the heating element has gone out of

[This review was collected as part of a promotion.] I love this blow dryer! I work behind the chair and run a 6 figure solo business, this is my most used tool. It’s lightweight, quiet and a power house! The warranty is great and it was honored when I sent in my blow dryer when the heat unit went out. It took about 10 days for me to make a claim and get it back. I highly recommend this blow dryer!!

[This review was collected as part of a promotion.] It's dries my hair fast! I would like it to have more heat to have my hair stay straight without frizzing.
