Love it! Best present ever
I’ve been really impressed with the Shark FlexFusion. It truly replaces multiple tools — dryer, straightener, brush, and curlers — which saves both time and space. I love that I can go from damp hair to styled hair without blow-drying first, and my hair feels smooth and looks shiny rather than dry or frizzy. The airflow is powerful and dries quickly, even with thicker hair. The straightener attachment gives a sleek finish, and the brush attachment creates a nice blowout look. There is a bit of a learning curve with the attachments, and it can get hot, so a heat protectant is a must, but once you get the hang of it, it’s easy to use. Overall, this is a great investment if you want one tool that can do it all and deliver salon-quality results at home. I’d especially recommend it for anyone who styles their hair regularly and wants to simplify their routine.

Game Changer!!!
I have lived with dry, frizzy hair my entire life and have only straightened it daily for the past 20 years or so- nothing ever seemed to help. This product has been a game changer. Not only can I style while it is still wet without damage- but my hair is so soft and full- it looks and feels amazing! Make sure you still use a heat protector. For busy moms like me- this makes me feel like I actually have a hair routine each day. It’s easy to hold and works quickly. I haven’t tried the curling barrels yet- but that is next on my to-do list. I love the round styling brush and hair dryer. Seems like a solid tool that should last for a long time.

My new favorite
The Shark FlexFusion has become my favorite hair tool. It dries my hair super fast without damaging it, leaves it smooth, and reduces frizz dramatically. The attachments work amazing: the round brush gives me a salon-style blowout, the straightening attachment leaves my hair sleek, and the curling barrel creates soft, natural waves. It’s lightweight, easy to use, and doesn’t overheat. The flexible handle also makes styling much more comfortable. Overall, it’s a complete and versatile tool that delivers salon-quality results at home.

Best hair of my life
This is the best money I've ever spent in my life. My hair is shiny, healthy and gorgeous. Holds the strapless. My hair has never looked better. I will never use another tool on my hair. This is the best!

Amazing All-in-One Hair Tool That Leaves Hair Soft & Shiny — Just a Bit Loud
I’ve been using the Shark FlexFusion Hair Straightener & Hair Dryer for a while now, and overall I really love it. It leaves my hair super soft, smooth, and shiny every time I use it, and I’ve noticed way less damage compared to traditional hot tools. My hair still feels healthy, not dry or fried. One of the best things about this product is how many attachments it comes with. Having the straightener, Fusion Hair Brush, Auto-Wrap Curlers, and concentrator all in one set makes styling so much easier and faster. I can dry, straighten, smooth, or curl my hair without switching between multiple tools, which is super convenient and definitely worth the price. The quality feels very solid and well-made, and the ceramic technology seems to distribute heat evenly. The Auto-Wrap Curlers are easy to use and give nice, natural curls without needing extreme heat. The straightener attachment also works really well and doesn’t pull or snag my hair. My only downside is the noise level. The dryer is a bit loud, which can be annoying, especially if you’re sensitive to sound. That’s the only reason I’m giving it 4 stars instead of 5. Overall, this is a great investment if you want an all-in-one styling tool that delivers great results while being gentle on your hair. If you don’t mind a little extra noise, I’d definitely recommend it.

Actually worth the money!
My hair is pretty damaged from coloring it, and my age, and that was my biggest reason for getting this Flex Fusion. It is absolutely amazing! I haven't even had to use my curling iron since I got this a few weeks ago! Icing on the cake, I often wake up and my hair still looks acceptable! Or I can spray a little heat protector on and spend two minutes or less to have it looking good again! I don't even have to use the curling attachments, it does a good job with just the brush drying it/ styling it same time. The curling attachments are really fun to use though, it just wraps your hair around it by itself as you move towards your scalp. I've never seen anything like it before! My husband was shocked at seeing my order for so much for this, and now he said he gets it, I'm ready in a fraction of the time and it is so much better for my hair! My hair actually looks healthier already. Less stressed. I would love it if this was not this expensive, but I have to say that is do it all over again. It is simply just worth it for me! The picture is just from blow drying with the brush attachment.

Would NOT buy Dyson over this great vac
Awesome vac. I can vacuum 4500sq ft floors with two dogs living in the house and it doesn’t even lose a charge. Turbo mode is awesome especially to pick up large things like cat litter. Great quality and good filter design. Highly recommend. Very glad I bought this instead of the overpriced Dyson equivalent which seems to suffer in ratings.

It is easy to use. My hair feels softer from not using heat anymore. The curl lasts all day and I have fine hair. Recommend this product.

Era justo lo que esperaba. La compré principalmente para la época de frío, en la que saliendo de bañarme quería secarme el cabello pero a la vez peinarlo. Funcionó justo como quería, me seca el cabello mientras se ve peinado. Fue una gran compra. Lo recomiendo ampliamente. Lo único "malo" es que la verdad es muy poco pesado y al estarme peinando se me cansa el brazo...

Increíble, todo en uno. Solo que si es súper pesado el cargador.
