  • Love this product!
Style: Smoothing Spray Size: 5.6 Ounce (Pack of 1)
This is an amazing product. I don’t even have to use a straight iron anymore. Just spray and blow out with a brush. It’s like a mini keratin treatment. Ive got stubborn wavy hair and this has been a game changer. My only negative is the strong perfume scent. It stays until washed and is very strong. I’m hesitant to use any other perfumes because it may clash. I don’t hate the smell, just wish it wasn’t so strong or last so long. ... show more

  • Magic in a bottle
Style: Smoothing Spray Size: 5.6 Ounce (Pack of 1)
This brand is truly magic. I don’t even have to straighten my hair anymore when I use this! Just spray and blow dry and I have a perfectly smooth and shiny blowout that smells so good!

  • It really works!
Style: Smoothing Spray Size: 5.6 Ounce (Pack of 1)
This stuff is amazing for my hair! I've tried tons of frizz control products that flopped, and living in this humid place, I wasn't shocked. But this one's different; it actually works! It felt like a mini keratin treatment – my hair was smooth and frizz-free for at least 24 hours, even in the rain. It's easy to use, but the smell lingers, so I use body spray to cover it up. Still, I'll totally buy it again and recommend it – the results are worth it. ... show more

  • Requires experimentation to get the amount correct; the fumes are pretty awful
Style: Smoothing Spray Size: 2.4 Ounce (Pack of 1)
For some reason, this took forever to be shipped. I'd seen the videos on social media and was excited to try it, so the wait was torturous. I used it on my first blow out after it was delivered. I have fine hair, so I errored on the side of caution and could have used more. The smell is just okay, but the fumes from the aerosol are absolutely awful. It legit makes breathing hard and my lungs are not a fan. I have to hold my breath before spraying, apply, and quickly escape the room to let it dissipate. I'm convinced that it works on my hair, but the fumes are toxic. I've used this about half a dozen times and I've learned that I need to be pretty precise with my application: I have fine hair, so too much close to my roots or on the top layer of my hair and it looks greasy, too little and I may as well not have used any, but if I get it *just* right? Shiny perfection! Would I buy this again? Maybe, but I'd only purchase from my beauty supply store where they sell it at half the retail cost, and I won't use it daily because the fumes seriously do make breathing a challenge. It does work and people with thicker or drier hair may find it a lot more forgiving when it comes to applying too much. ... show more

  • Great results on my thick, curly hair
Style: Smoothing Spray Size: 5.6 Ounce (Pack of 1)
I have pretty thick & coarse hair with some sections that are curly & some are wavy. This spray is incredibly lightweight! It smooths my hair & eliminates all frizz. I LOVE the smell of my hair after it’s dried & I catch a whiff😅However, the smell of the spray when it’s first applied has me gagging & running for the bathroom window to get a breath of fresh air. Overall, I will continue using it & recommending it to others. ... show more

  • Works so nice on straight hair!
Style: Smoothing Spray Size: 5.6 Ounce (Pack of 1)
I have thick straight hair and it makes it so light and shiny and smooth. It is a bit expensive so I try to stock up on sales.

  • Update: does work in a particular way. DOES NOT WORK!!
Style: Smoothing Spray Size: 5.6 Ounce (Pack of 1)
Update: this product does work, however, I found the trick to ot is to wash your hair and while it is still wet spray this product in and blow dry with brush or air brush. I have curls and it will take out all your curls but it will keep your hair from frizzing and give it a nice shine if you put it on while your hair is wet, not damp. Flattens, straightens, makes it crunchy NOT SOFT, the scent is HORRIBLY OVERWHELMING, does not make it Shiney, and does not take the frizz out ... show more
