    The Shark FlexFusion Hair Styling System does a great job in combining multiple hair tools into one device. In addition to the multiple tools, there are multiple setting options which allows for a more customizable use. Unfortunately for me, after about 1 week of use I was left a bit underwhelmed with this device. My hair is on the denser and thicker side, is medium length, dries straight, and does not hold a curl well at all. Upon first use, I thought the Styling tool was awkward to hold due to its design. The “handle” or grip area is the same size as its extended barrel and is bigger than all hair styling tools that I use. While initially awkward, I was surprised at how quickly I became comfortable with it after a bit more use. I also found the hair dryer, due to its barrel size, to be lacking in volume although the velocity was impressively powerful. The smaller barrel size of the dryer reminded me of the mini hair dryers that are often provided in hotels, which is why I often pack my own hair dryer. I thought the hair dryer provided good heat at the highest setting and never found it to be excessive. All settings had noticeable differences, from temperature to fan speed. Compared to my normal hair dryer, I felt that it took longer to dry my hair with Shark FlexFusion. After using the dryer without any attachments I opted to use the FusionBrush to help speed up the process. While it did seem to help, I did not like having to brush through my hair with a bristled-tool as much as I did in order to dry my hair. I did find the styling concentrator attachment to be helpful for drying detailed spots of my hair, specifically with my part and side-swept bangs. The Auto-Wrap Curlers were the most pleasant surprise for me. The attachments actually did a good job curling my hair, as long as it was in very small batches due to the density of my hair. I thought the Auto-Wrap feature was really cool. I can see how it would help speed up the process for curling one’s hair, but for me, I felt that the noise level was too much to tolerate for the extended length of time (about an hour) it takes to curl my hair, especially considering that a regular curling iron makes nearly no noise. Last, I found the Fusion Air Straightener attachment to work very well, with great heat control. Although I don’t straighten my hair while wet (because it dries straight naturally), I found the option to dry and straighten wet hair simultaneously with this attachment to be very innovative and likely a time saver for those who would use it that way. Overall, I think the Shark FlexFusion Hair Styling System is a useful tool for many people who are looking to condense the amount of hair styling tools they own or simply for traveling purposes. For those with dense, thick or long hair, this tool might be a bit underwhelming, like I found it to be, but for those with hair of average density and thickness or shorter hair, this styling tool might prove to be not only a space saver but a time saver as well.

    Beautiful looking system but too much work to use

    I really like the beautiful mauve color that the Shark FlexFusion system comes in. It’s even prettier than the lavender color of the FlexStyle system. The darker accent color on the brush and straightener is just the right offset, making it a very classy looking set. If I judged by looks alone, I’d give it all thumbs up, but of course, that wouldn’t be a practical reason to get a hair styling system like this one. Unfortunately, though, the versatility of the system really didn’t live up to my expectations in using it on my thick, longish length hair. A plus is that the blow dryer, when used on its own or with the brush accessory, did dry my hair in half the time it normally takes. But it took twice as long with the curling wand or straightener attached than usual. The FlexFusion dryer is slightly heavier than the FlexStyle one, but it is also irritatingly loud. Loud to the point that I suggest wearing some quality earplugs to protect your eardrums when you’re using it. The bulky power cord is heavy also, adding to the weight and strain of the dryer on your arm during use. Use it with the straightener attached and you’ll almost need a crane to lift your arm! The straightener added also makes the dryer almost 2-feet long and that’s a lot of bulk to have to deal with. I want to dry and style my hair, not lift weights! The weight of it with the other included styling attachments was much more manageable. Even though it was somewhat of a pain having to switch between a left and a right curling wand for uniform spiral curl direction, the spirals looked great. The curls, however, were short-lived and needed a do over after 2-3 hours. And it seems they lasted the longest when I styled from dry hair than from wet. I didn’t get the full benefit of using the straightener attachment because it was just too unwieldy and awkward to use on my entire head on my own. Even after trying the FlexFusion system various ways multiple times, a regular dryer, flat iron and curling iron is less strenuous and more efficient in my opinion.

    The Shark Flex Fusion is a multi-styler with air straightening technology embedded into it. This styler states its for all hair types. To give you an idea, I am multi-ethnic and consider myself African American with European and Native American heritage. My hair tends to be thick, wavy, and have a curly texture. I tested the unit when my hair was wet and when it was dry. When using the blow dryer, the dry time was reduced in half of what I am normally use to. The box states that it has scalp shield. I can verify that as I was blow drying the hair dryer did not make my scalp dry. I did not feel heat on my scalp, which was nice. In addition to this, when use the ahir dry I attached the wet-or-dry brush which assisted in ensuring that my hair would not become tangled. The unit also came with curlers to curl your hair and in addition with a styling concentrator. I did not care for the styling concentrator. The concentrator is supposed to be used along side a brush to help distribute the heat evenly. For my type of hair, and having to do multiple things at a time, this was not a good fit. The flat iron that fits with the unit, did press my hair out as stated, but it did take a bit of effort. Unsure if this is because of the type of hair I have. The following morning, I used the unit again, with this time my hair being completely dry and it did flatten my hair out. So that is why I am knocking two stars down for the application of the heat. Is this a deal breaker for what the unit can do, no. It just depends what you are looking for. I love the concept, but I am used to other irons, that in one stroke the heat distributes quickly and flattens. However, those type of irons do not have the scalp technology embedded within them. I do recommend investing in a wide tooth comb, if you have my type of hair, instead of using the styling concentrator. I think if that would have comb with the unit for me to test, I would have seen a major difference. Overall, I feel the product does a good job, however, I cannot at this time give it 5 stars. Pros: Scalp Technology Can dry hair while wait quickly Curly units that can attach to the dryer Various heat settings and attachments Cons: Needs Teeth Comb unit for thicker hair

    Awkward + Definite Learning Curve

    |
    Tech Insider Network Member
    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    To start with, let me tell you about my hair: I have baby fine, stick-straight, long hair (hits about mid-back when it is down) that typically refuses to do anything other than be straight (and, especially in the winter, very, very staticky). It also gets oily at the root/on the scalp easily, so I don't typically use much in the way of product which doesn't help with styling. I'm always looking for something to do with my hair (other than a ponytail), so when I got the chance to try this, I jumped on it. I really like the fact that for most of the tools it harnesses the power of drying your hair while styling because a. I'm lazy and because my hair never does what I want it to, I'm usually a wash and air dry type of person and b. I feel like for my type of hair drying it while styling it gives it a little extra hold (with the help of a ton of product). This guy...well...I think I was a little overexcited about how easily and perfectly it could theoretically style my hair. Is there potential? For sure...but I only really got to use it a handful of times (pretty much 1x/tool attachment) in the couple of weeks I had with it prior to needing to review it, so hopefully my hopes are not misplaced! Pros: - the majority of the tools are used on wet hair, which helps set the style and saves time (you aren't having to dry your hair and then get out another tool to curl, etc) - you get multiple styling tools in one device - I actually had curls in my hair! - I love that there is a right and a left side curling attachment so your curls are styled in the same direction! Cons: - it is very long/large, and very awkward to use, especially if you are doing anything other than blow drying your hair - There's no manual on how to use any of the attachments. There are instructions on the packaging, but let's be real - it's annoying to have to keep a huge box around just to have tips/tricks/instructions on how to use the thing - Even with the instructions printed on the box, especially with the curling attachments, it was a lot of trial and error. I'm sure with time I'll get it all straightened out, but it was disappointing for it to be so hard (I'm thinking it would be easier for those with shorter hair) - while using the attachments (specifically the curling attachments), the parts of my hair that wasn't getting styled at the time was constantly getting sucked up and wrapped around the very end (cord end) if I held it anywhere near my hair. Again, I'm thinking it was an issue for me more because of the length of my hair than anything else. All that to say...I'm gonna keep going with it, and hopefully find some video tutorials online to learn how to use it. I think it has a lot of potential, and once I get more comfortable with all the different parts, I think it will work as I expected which is why I'm not rating it lower than I am.

    This styler is a total game-changer. It has replaced my separate hair dryer, straightener, and curling wand. It dries my hair incredibly fast, leaves it smooth and frizz-free when straightening, and the auto-wrap curlers give me perfect curls that last all day. My hair already feels healthier and looks shinier. It's absolutely worth the investment for salon-quality results at home!

    This thing is great!! So easy to use, I’m not a hair girlie so I need all the help I can get to achieve a style. This thing is super easy to use, it works, leaves my hair soft and shiny. Only thing is it’s loud, way louder than my Dyson hair dryer. But I don’t use it for that.
