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.

Smoothes my hair but strong scent
Hair Type Straight Hair
This leave in treatment definitely works well for my hair (East-Asian, straight, non-colored). My hair does feel smoother without the feeling of greasiness some treatments leave. It helps with the frizz of my baby hairs on the top of my scalp which is a nice plus. The only personal downside for me is the scent. It resembles a bit of strong men's fragrance, which definitely could be something that is okay. for you, but honestly, not my cup of tea. Overall, pretty nice treatment, but strong fragrance.

Luxe packaging for smooth hair
I received this product for free from Topbox Marketing for testing and review purposes. First off, the packaging for this product is ver luxe.. it is not plastic and has some weight to it. It looks beautiful on the shelf with the metallic purple color. Onto the product itself, i used it both with damp hair before blow drying and on dry hair. I prefer to put it on damp hair. I do notice after using it consistently for a couple weeks, my hair does feel silkier. The one thing i didnt love was the scent. It is fairly strong when you first put it on, but does eventually fade.
Great hair product
This hair product is doing great on my hair, it did not leave sticky feeling on my hair. Also I feel my hairs very soft after use"I received this product for free from Topbox Marketing for testing and review purposes."
Really works wonders
Hair Type Wavy Hair
This product smells absolutely AMAZING! It really helped my hair to look healthier and shinier even after just one use. I noticed less frizz and more manageability. I really like this serum/treatment and will be adding it to my routine. I received this product for free from Topbox Marketing for testing and review purposes.
