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.

Very functional
This Shark hair dryer has been one of my best purchases. It is extremely functional and works perfectly. It dries my hair quickly without damaging it, and it’s easy to use. The design is practical, lightweight, and very convenient for everyday use. The quality is excellent, and it truly makes a difference in my hair routine. I highly recommend it

Just buy it
I have been eyeing this product for a couple of years now. I was hesitant to purchase one because of the price, but two because I have all these same tools, just in a separate package. However, my life now is such that I am traveling and there was a substantial sale so I did it, and I am so happy I did. Pros: I love the temperature controls allowing for lower heat when styling and drying wet hair, as well as the scalp control allowing for you not to burn the fire out of your face when styling the front sections. I love the convince of having all these features in one tool. I really like the quality of the style I am able to achieve. Cons: I have really long thick hair, so no matter what product I use it is going to take time to section and style my hair. With that being said this is slightly on the heavy side. I also felt like the balance was odd, and will take some getting used to when using the tools as the tool attachment extend the overall length making it something to get used to. The last con is the fact that it is several pieces, so while it is easier to travel with because it is more compact than all these tools separately, I will need to look for a travel case to keep it all together. While I do not feel the cons are worth a deduction in stars, it is something to consider if something has limitations with their mobility. Overall I am super happy with my purchase and would recommend it.

Must Have!
I have thick, coarse, type 2B hair. With a normal round brush and hair dryer, my hair takes about an hour and a half to blow-dry and style. This product is an absolute game changer! Within 30 minutes my hair is completely dry and silky smooth! Every attachment works perfectly with little to no frizz! Love love love this!

Good purchase
Works great. Dries hair quickly. Makes getting ready so much faster. It is a bit heavy to hold but manageable. Lots of attachments to meet all the style needs.

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.

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.

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...
