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...

Less Fallout, More Softness: My Nexxus Keraphix Review
I've been using the Nexxus Keraphix Repair Liquid Crystallizer Reconstructive Leave-In Treatment for about a month now, applying it after every hair wash, and I've honestly noticed a difference. The first thing I noticed was how much softer and smoother my hair feels—especially on my ends, which usually feel dry and fragile. Over time, I've also seen less hair fallout, which tells me my hair feels stronger and more resilient overall. This makes sense since the Keraphix line is formulated with protein and keratin-building technology designed to help repair damaged hair from the inside out and reduce breakage. My hair feels more manageable, looks healthier, and doesn't feel weighed down or greasy after applying. I love that it works as a leave-in treatment without needing extra steps, and it layers well with my other styling products. If you're dealing with damage from heat styling, coloring, or general breakage, this is a great option to help restore softness, strength, and shine over time.

Great
Hair Type Straight Hair
I've used this leave-in treatment for about two weeks and I'm very happy with the result. I mainly using it after washing my hair at night. It absorbs quickly into my hair, doesn't leave any residue or weight down my hair. It also does a great job of moisturizing my splits end. The scent is pleasant without being overpowering. It makes my hair feel smoother and healthier. The purple bottle is gorgeous, with the pump dispenser makes it easy to get the product out.

It's a yes for me!
Hair Type Wavy Hair
It is so difficult for me to find products that tame and repair my long, thick, wavy hair. I think I've found the perfect product with Keraphix leave-in treatment. First off, as soon as I pumped the product into my hand, I knew I was going to love this product just based off the amazing, fresh smell. This product not only smoothed my sometimes frizzy hair, but as I've been using it, it's actually repairing damage. Also who doesn't love a shiny purple bottle for their hair product. Definitely a 5-star product! I received this product for free from Topbox Marketing for testing and review purposes
