"I absolutely love this product! The first time I used it, I applied a bit too much, and my hair felt slightly sticky the next day. But I quickly learned that just a little goes a long way to eliminate frizz and add shine. Blow-drying my hair before using it definitely helps!"

"After trying the Color Wow Dream Coat spray, I was excited to try this, and I'm so glad I did! Just a small amount gives my hair shine and volume that lasts all day. My only drawback is that it can feel a bit sticky."

"I use this product almost every time after I towel dry my hair. It has become an essential part of my hair care routine, providing the perfect balance of moisture and hold. When I wear my curls, I pair it with Ouai curl cream for smooth, frizz-free results. It's versatile for both curling and straightening, consistently delivering great results. Highly recommend!"

"I have curly fine hair, and most products weigh it down, but not this one. I use just half a pump with some curl cream, and I get soft, shiny curls without any stickiness or greasiness. I believe this is improving my hair's health and moisture, and it's definitely worth the price!"

"This product has surprisingly worked well for me! I applied it to my dry hair, focusing on the ends and fly-aways, and it made my hair look significantly less frizzy and much sleeker. It feels like magic, and I love that it doesn't make my hair feel stiff or sticky. It's now a regular part of my routine!"

"I absolutely love the GK Hair Smoothing Serum! After just a few uses, my hair feels incredibly smooth, sleek, and healthy. It adds a beautiful shine and makes styling so much easier. The best part? Even the next day, my hair stays smooth, and there's no flyaway mess to deal with. I highly recommend this serum for long-lasting, salon-quality results at home!"

"After searching for a natural, non-toxic hair product without my allergens, I was thrilled to find this on Amazon. The product was labeled as having very few ingredients, which matched what I found on the manufacturer's website. However, when it arrived, I was disappointed to see a much longer ingredient list, including artificial colors and chemicals, as well as benzyl alcohol, an allergen for me. I returned the product immediately due to the lack of transparency in the ingredient listing."

"I love how compact the bottle is; it fits perfectly in my makeup bag! A little goes a long way, so don't let the small size mislead you. I have fine, curly hair, and this product works wonders to give my hair full body and shine without any frizz. My curls look thick and lovely, and I adore the scent. This product is definitely among my top five hair care products!"

"I tried this frizz tamer on a whim, looking for something that would truly tame my frizzy hair for an entire day or night, and I found that this product is EVERYTHING. Fast and easy to apply, it does not look greasy at all and keeps the frizz under control without feeling stiff. I love the pleasant, neutral smell as well. As my hair has grown courser with age, I will be buying this for years to come!"

"I used to use another brand's serum wand, which was good initially but dried out quickly. This product tames those stray hairs and smooths them down effortlessly. So far, I haven't had one that has dried out. It gets the job done and offers great value for the price."

"This product works well and has a nice scent. It's not greasy or sticky, and it feels light with a very gentle hold. I love keeping this in my purse for easy access. However, it does get stuck in my hair every time I use it, which can be quite frustrating because it pulls out styled hairs!"

"I’ve struggled with frizzy hair for years, especially in the back. I recently purchased John Frieda Frizz Ease Beyond Smooth Shampoo & Conditioner and Frizz Ease Extra Strength Hair Serum. After trying these products, I'm thrilled with the results—no sticky residue and, most importantly, no frizz! I regret spending money on expensive salon products that didn’t work. I'm sticking with John Frieda from now on because it's affordable and effective!"

"This product works wonders for me. I love that there are no flyaways and it doesn’t leave my hair greasy. Just a little dab goes a long way, and it really helps to strengthen my hair while protecting it from heat styling tools. Plus, it has no scent and leaves my hair feeling incredibly soft. I would highly recommend it!"

"Living in a dry climate, I really needed something to combat static and frizz. John Frieda Anti Frizz has been a game changer for my slightly curly hair. It's been a while since I've used John Frieda products, and I forgot just how effective they are! My hair feels so silky and frizz-free after using this. I will definitely buy it again!"

"I bought this on a whim after reading reviews, and I'm so happy I did! It’s incredibly kind to my thin, fine hair. My hair feels so much softer and looks shiny after drying. I've used it every wash, and I’m consistently pleased with the results. The scent is lovely—not too strong, just the right balance. The spray nozzle is effective, providing an even mist without weighing my hair down or making it oily. I highly recommend it for anyone wanting extra hydration and shine."

"Having thick, long hair, I tend to go through products quickly, but I love how this one makes my hair look and feel. It transforms my hair from frizzy and dull to smooth and shiny. My only complaint is the amount I use given my hair's thickness, but that’s not the product's fault. I wish they offered larger bottles! For the times I have used it, it's been fantastic."

"This is now my favorite hair product! With my thick, coarse curly hair, it helps keep my hair more manageable and less frizzy. After using it, my hair feels softer and looks smoother. I really appreciate the great price for such an effective product!"

"I've been using this Amika heat protectant for years, and I can't imagine being without it! The scent is incredible, and it protects my heat-styled hair perfectly. The consistency is just right, not too watery or heavy, which is great for my fine hair. I even use it on my wavy hair as a styling product. Love love love this!"

"I recently tried this product for the first time, and it was fantastic! It protected my hair and left it smelling amazing and feeling incredibly soft. My fiancé noticed and complimented it multiple times! The only downside is that it can make my hands a bit greasy, but the easy-to-use bottle makes up for it. Can't get enough of this heat protectant!"

"I absolutely adore this product! It makes my hair feel amazing and healthy, even after using heat styling tools. This is truly a game changer for my hair care routine. The seller was great, with fast shipping and careful packaging. This is a product I’ll be buying forever!"
