Q: Hello, I just received the product and highly doubt its authenticity. How can I make sure it's authentic? I need a proof for it. I feel the packaging and the texture is different from the real one....

submitted by Lily - 1 year ago
  • A: Hi Lily! We are so sorry you are not happy with the product you received. All of our products are 100% authentic because we only purchase directly from manufacturers and authorized distributors. If this product has a batch code, you should be able to look it up and verify the authenticity. Additionally, if this product was delivered and left out in the heat, this may effect the texture. Products can become defective if left out in the heat or cold for too long. If it appears that this product has changed in texture or the formula doesn't seem right from one of these issues, please contact Target to get a return started.

Q: How is this different from the 5 oz leave in size other than size? While they're both worded differently, the outcome of the products seems the same. Are they 2 different hair masks?

submitted by Coco - 2 years ago
  • A: Hi Coco! The 5 oz mask is a mask you use in place of conditioner that needs to be rinsed out. The 1.7 oz you do not rinse out. They both do similar things, but if you have more damage you may want to go with the 1.7 oz because that will be in the hair longer.

    🚨 **BEWARE — POSSIBLE COUNTERFEIT K18 PRODUCTS! DO NOT BUY!** 🚨 I purchased these K18 products through Target.com believing I was purchasing authentic K18. After receiving them, I immediately noticed differences when comparing them side-by-side with my authentic K18 product purchased from Sephora. The packaging has **visible differences in the font, spacing, printing, labeling, and overall quality**. Even more concerning, the manufacturing information does not match my authentic product. I contacted the manufacturer directly and provided the information from the products I received. Based on the discrepancies, I was advised that they are **most likely counterfeit**. I have filed a formal complaint, and I was told the matter will be investigated and escalated through the appropriate channels. I later realized these were purchased on Target.com through a **third-party Target Plus seller**, not directly from Target. Please be extremely careful. K18 is an expensive professional hair product, and something applied directly to your hair and scalp is NOT something I would take a chance with. Compare your packaging carefully and verify your seller. I will absolutely not be using these products and have requested a full refund. **Target needs to investigate this seller and how potentially counterfeit beauty products are making it onto its marketplace.**

    Fake!

    This product is a fake! There are specific characteristics of the authentic product and it's packaging that this fake does not have: 1) the consistency should be like a medium lotion that can be vigorously distributed between hands resulting in a thicker mask-like product--this fake is thin and almost watery; 2) the packaging should have specific information and symbols such as a list of ingredients, a bar code, recycle symbol as well as the k18 website and distribution info under its parent company AQUIS Hair Sciences--this fake has none of this info.

    Awesome

    I was skeptical to buy it since it was a third party seller. I had read bad reviews online that third party sellers are selling fake products. Anyway I took a risk and bought it. Pricey but I have to say it did make a difference on my dry and brittle over bleached hair.

    Counterfeit Seller

    Scam alert! This product is not authentic K18. I could tell from the first pump of this product that it is not the real hair mask. Texture, color, and smell are all different, plus the bottle itself has different design on the back than the original.

    Not Sure Yet

    I have naturally curly hair that is heat damaged. My hair felt stronger and smoother after one use. It made detangling my hair so easy, and it smoothed out my flyaways. Haven’t noticed any curling in the heat damaged area yet though. I needed way more than the recommended max of 3 pumps, but I have long thick hair. Will probably need another small bottle to make it to the recommended 4 uses.

    Wonderful

    After just one use my hair feels like silk! I have a lived in blonde balayage. My hair is thick but fine with a naturally frizzy wavy texture. It’s been feeling dry and I noticed my ends were splitting faster than usual after my last big chop. I followed the instructions exactly. My hair needed three pumps total. I left it in and didn’t wash it out. I was worried my hair would dry greasy or weighed down but it totally didn’t!
