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...

Nexxus leave in conditioner
I've been using this product daily for awhile now and its great! It smells so good and doesn't leave my hair weighed down or sticky. I use this when slicking my hair back to keep it healthy. I would repurchase. I received this product for free from Topbox Marketing for testing and review purposes.
Shiny, Smooth, and Stronger Hair—Instantly
Hair Type Wavy Hair
I've been using the Nexxus Keraphix™ Liquid Crystallizer Reconstructive Leave-In Treatment for a bit now, and I'm seriously impressed. It instantly makes my hair feel softer and smoother without weighing it down. My ends look healthier, frizz is noticeably reduced, and I get that glossy, salon-level shine every time. What I love most is how lightweight it is—it absorbs quickly and doesn't leave any greasy residue, even on fine or damaged hair. It also helps with detangling and makes heat styling feel less harsh on my strands. My hair feels stronger over time and looks more polished overall. If your hair needs repair but you still want softness and shine, this is a great add to your routine and easy to work into a daily routine. Definitely a leave-in I'll keep reaching for!

Light, gives nice shine but lost bounce
Hair Type Wavy Hair
It is very light, gives nice shine and smooth texture after the application. Smells great. The only problem i had was I lost little bounce on my hair. I think this will be great for straight hair or to control frizz. I did see difference in my hair texture after 3-4 days, my hair did feel rough and needed wash.I typically wash my hair every 3/4 days so was not a problem I received this product for free from Topbox Marketing for testing and review purposes.
Definitely keeping in my hair routine!
Hair Type Wavy Hair
Gifted by Nexxus via TopBox for my honest review I've been using the Nexxus Liquid Crystallizer and this one really surprised me in the best way. If you're looking for shine without weighing your hair down, this does exactly that. It smooths, adds gloss, and helps tame frizz while still leaving my hair feeling soft and touchable. What I love most is that it doesn't make my hair greasy or stiff. A little goes a long way, and it layers beautifully whether I use it on damp hair before styling or as a finishing product on dry hair. My hair looks healthier and more polished without feeling coated. The texture is lightweight, the scent is clean and salon-like, and it plays well with heat styling. This is one of those products that makes your hair look "done" without trying too hard. If you want smooth, shiny hair with a lightweight feel, this one is definitely worth checking out.


Overall good product
I have fine hair, but a lot of it with some color and heat damage. Ive used every leave in under the sun. This one doesnt shine above all, but is definitely one that does the job well. I wouldnt say that there is anything inherently special, but the shiny design and texure is appealing. I received this product for free from Topbox Marketing for testing and review purposes.
