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...

Not revolutionary but it's good
I didn't notice a major difference from this product vs others I've tried in the past but it had no negative effects either. I received this product for free from Topbox Marketing for testing and review purposes."
Great hair serum
Hair Type Wavy Hair
This hair serum has a lot of good and clean ingredients. It made my hair more healthy and shiny. I saw a difference after a few days .
I loved it!
Hair Type Straight Hair
This made my hair so smooth and sleek looking and I could barely tell that I had heat damage. My hair definitely felt stronger after using this and my split ends looked a lot better too. I think the scent was very nice as well and gave the product more of a luxurious feeling. I received this product for free from Topbox Marketing for testing and review purposes.
Solid treatment
The Nexxus Keraphix™ Liquid Crystallizer Reconstructive Leave-In Treatment is a solid protein product. I used it about once a week at first then once every two to three weeks depending on how much stress I was putting on my hair. It made my hair easy to blow dry for straight styles and kept frizz to a minimum for natural wavy days. I think it's smells wonderful, but for scent-sensitive people, the scent does fade rather quickly. Just like with any other protein treatment, when used correctly I think this is a solid product.
