[This review was collected as part of a promotion.] This is a wonderful leave in treatment! First off, I'm loving the shiny purple bottle, so luxurious, the product in itself is nothing short of a miracle. I have damaged hair and splits ends, after a few uses, this repair cream took care of all those issues! It left my hair nourished, repaired and strong. I apply it when my hair is damp and then proceed to style it as usual, I prefer this method than applying it on dry hair! All in all a wonderful cream that fixes many hair issues!

[This review was collected as part of a promotion.] I received this product a few weeks ago and have using it daily! The difference it has made instantly to my hair is quite unbelievable. It leaves my hair with a nice soft and silky look and the smell is phenomenal. The product says that it can be used on wet or dry hair. When I use the product on wet hair it brings out my natural curls. When I use it on my hair when it's dry it leaves it looking soft and tames the frizz. This is by far one of my favorite hair products now. I received this product for free from Topbox Marketing for testing and review purposes.

[This review was collected as part of a promotion.] I absolutely love the NEXXUS KERAPHIX Repair leave-in-treatment. Upon first use, my hair feels so soft and silky, like it's never been damaged or dyed. I can't believe the difference in just one use, and I know this will be a staple product for my hair from now on. Usually, when buying hair products, I haven't found one that not only makes my hair look good but also corrects the actual damage. I feel like this treatment is more than just a leave-in; it's fixing years of damage caused by heat and styling. I truly love the scent as well, it gives my hair that clean, refreshed smell that I usually get from a day at the salon. Overall, the NEXXUS KERAPHIX leave-in treatment deserves more than just 5 stars. I love it! I received this product for free from Topbox Marketing for testing and review purposes.

[This review was collected as part of a promotion.] I've been using the NEXXUS Keraphix™ Liquid Crystallizer Reconstructive Leave-In Treatment, and honestly… this feels like the “reset button” my hair has been begging for. The first thing I noticed was how lightweight it is—no heaviness, no greasy ends, just this soft slip that makes detangling way easier. My hair usually gets stressed out from heat and constant styling, but this leaves it feeling smoother and a little stronger every time I use it. The shine is what surprised me most. It's not that fake silicone shine—it actually looks healthier, like I've been taking care of it for weeks when it's literally been a few days. And the best part is it doesn't flatten my volume. My hair still moves, still feels like my hair, just less frizzy and more put-together. If your hair has been through breakage, coloring, or a little too much heat (guilty), this is one of those treatments that quietly works in the background and you don't realize how much you needed it until you skip a day. Definitely staying in my rotation. I received this product for free from Topbox Marketing for testing and review purposes

[This review was collected as part of a promotion.] I've been using the Nexxus Keraphix™ Liquid Crystallizer Reconstructive Leave-In Treatment mostly during the daytime on towel-dried hair, and I'm really impressed with how smooth and healthy my hair feels. The texture is lightweight and absorbs quickly without leaving any greasy residue. I loved the soft, clean scent—it smells fresh and salon-like but not overpowering. After a few uses, my hair looked shinier, felt stronger, and was much easier to detangle and style. It helped reduce frizz and made my ends feel less dry and damaged. Overall, this leave-in made my hair feel nourished, soft, and polished throughout the day. I received this product for free from Topbox circle for testing and review purposes.

[This review was collected as part of a promotion.] This leave-in treatment is a game changer if your hair needs serious repair without feeling heavy. The lightweight formula absorbs instantly, smoothing rough, damaged strands and adding a soft, glossy finish. It helps reduce frizz, improves manageability, and leaves hair feeling stronger with each use. I love that it delivers salon-level nourishment while keeping my hair bouncy and touchable. If you're dealing with breakage or dull, over-processed hair, this is a fantastic treatment to add to your routine.

[This review was collected as part of a promotion.] I've been using Nexxus Keraphix Repair for a while, and it truly feels like a salon-level treatment at home. The protein-rich formula strengthens hair from root to tip, making it noticeably softer, smoother, and shinier, especially on damaged or color-treated strands. While it's ideal for hair that's brittle or heat-damaged, I'd recommend using it in moderation if your hair isn't heavily damaged, as too much protein can feel stiff. Overall, it leaves hair touchably soft, nourished, and visibly healthier without feeling heavy. I love this product, it made my hair look and feel amazing. What I don't love is the fragrance; it's a bit too strong for my liking. Even though I'm usually a huge fan of fragrances, the notes in this one just don't feel as pleasant. I wish it came in a subtler, more soothing scent that matches how good it makes your hair feel. I received this product for free from Topbox Marketing for testing and review purposes.

The amount in the bottle was not what I would have expected given the price. The bottle is pretty so maybe that's what I paid for. I can't say if it made a difference because i only got 3 uses out of it.
