Next Level Leave In - Salon Softness Achieved

Let me start by saying this leave in treatment is absolutely phenomenal and that is not something I say lightly. I have long, thick platinum blonde hair that I take exceptionally good care of, but it can still feel dry at times, especially when the weather changes. This treatment completely transfor...

Not for me

I really wanted to like this product a lot more than I did but I feel a little in different about it. Some of the time that I used it, it made my hair really soft afterwards and other times it left it feeling a lot more dry. I'm not sure if it's just not for my hair type in which I have both oily an...

It works really well on fine, frizzy hair

I can't think of a single time that I've ever been able to blow dry my hair and not have to straighten, curl, or put it up after because of how frizzy and poofy it gets until I used this product. I literally blow dryed and was ready to go! I know that might not mean a lot to some folks but for me, it means A LOT. The only reason I hesitated in buying it is the price point but it's well worth it in my opinion. It smells nice. Not overpowering after it's dry. It didn't weigh my hair down like other stuff I've tried in the past. The glass bottle is pretty and fancy but I worry it might slip out of my hands and break while using it. Adding a silicon wrap or something similar might make it a little less likely to break if anyone from Nexxus happens to read these. Overall, if you are hesitant like I was, and you have dry, frizzy, fine hair that you can't tame without a straight iron or curler, take the chance.

I have tried this product in the past few weeks, I love it. I can see the results in the first couple of uses. My hair looks nourishing, smooth and healthy. I can use it when my hair is dry or damp. No more dry and unhealthy hair! I received this product from Topbox Marketing for free for testing and review purposes.

Actually amazing

This is an impressive treatment for damaged or stressed hair. The lightweight liquid formula absorbs quickly without weighing hair down, making it perfect for daily use on both damp and dry hair. After applying, my hair felt noticeably softer, smoother, and easier to manage, with less frizz and enhanced shine. It works beautifully as a prep step before styling and leaves hair looking healthier and more polished overall. With continued use, hair feels stronger and less prone to breakage! a major plus for anyone who regularly heat styles or colors their hair. I received this product for free from Topbox Marketing.

Hair Type Very Curly Hair

Great product to use on my damaged hair! I had tons of split ends and would also experience breakage after washing and brushing my hair. I noticed a difference instantly. After using it, my hair looked and felt more voluminous and so much healthier. I also had very minimal hair breakage when brushing after using this treatment as well! I'm so happy!

Having a color treated hair, overtime, the ends become so dry and brittle. With this product, it has restored it's shine, my hair's more manageable, and less frizzy. And, I love the scent, just a clean fresh scent. I received this product for free from Topbox Marketing for testing and review purposes.
