Style: FlexFusion Straight & Wavy Hair
Review Image by Amy Ortega
My dream come true, I have a very curly hair. My curly hair type is 3C4 an and to be honest with you the size of these flat iron. It is not flat at all, but the results is a little bit. It’s a little bit tricky at first to get your right place into your route that’s the part that II have a very curly hair. My curly hair type is 3C - 4A and to be honest with you the size of this flat iron. It is not flat at all, It’s a little bit tricky at first to get your right place into your route that’s the part that I have difficulties with however, when you get to try it and get to practice I think this is one of the best flat irons or silk press methods I have ever tried because compared to other flat flat irons of mine. This one doesn’t kill volume I believe this is one of the most voluminous silk press I have ever had so if you have curly hair or you’re only straight girl go for it because not only has flat irons also other four attachments. I absolutely love the barrels the curls turns out very, very, very cute so I honestly loved it and love this rose gold color. It is a very big tool, but I believe it is very easy to use is also a little bit heavy but as acrylic girl, I appreciate a lot the technology of it because my calls didn’t suffer the consequences of the heat damage, even though I protect my hair from heat with heat protectant I think this wasn’t a too abrasive hot tool for my hair type ... show more

    • WOW!
Style: FlexFusion Straight & Wavy Hair
Wow, just wow. I don't think I have ever had a blow drying/straightening tool be so effective before in my life! As a college student, there are a lot of instances where I simply don't have the time nor energy to wash my hair, so I often only have a couple of "hair wash" days a week. In between those days, I typically like to straighten my hair because it's a lot easier to manage and just feels a lot cleaner and put-together to me. I used to dread straightening/blow drying my hair because it was such a tedious task that I felt forced to do because I usually take night showers and you aren't supposed to sleep with wet hair yada yada yada. Also because I have very thick, curly hair that would usually take a lot of elbow grease to get completely sleek and straight. But enter the Shark FlexFusion tool... this tool has been such a game changer! I don't usually buy overly expensive things for myself so I really stepped out of my comfort zone to splurge on this and when I tell you, every penny spent was worth it. I love how it comes with like five different attachments so I can use the same tool for multiple different things. It is also so, so QUICK! I timed myself straightening my hair and I kid you not 20 minutes MAX!! (It literally used to take me over an hour to straighten my hair with other straighteners). You can also work with pretty big sections as well. And on top of that it actually does a great job, my hair looks so sleek and it's not frizzy or poofy after straightening at all. Overall, this tool is amazing and I no longer can imagine my life without it. ... show more

I bought it as a gift for my girlfriend, and she was delighted with all of its features. It feels robust and high-quality. She even says she doesn't need to go to the beauty salon anymore since she can do her hair by herself

    • Just WOW! Love it…
Style: FlexFusion Straight & Wavy Hair
I purchased the Flexfusion model and it works great and as advertised. The power and airflow work well. Blow drying and curling my hair in no time. Beautiful curls. I have not used the straightener yet, but I’m sure it’ll work just as good. So far no complaints. I had purchased other similar products and this is by far the best. Happy customer! FYI I purchased the warranty just incase of any future problems. Fingers crossed. ... show more

    • Amazing All-in-One Hair Tool That Leaves Hair Soft & Shiny — Just a Bit Loud
Style: FlexFusion Straight & Wavy Hair
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. ... show more
