It's ok but there's better ones out there.

I had high hopes for this leave-in conditioner, especially with all the promises of multi-level repair, hydration, and split-end mending. And while it does deliver on a few things, I'm honestly left feeling a little underwhelmed for the price and hype. First, the good: It definitely made my hair fe...

I've only been using the No.5 Leave-In™ Moisturize & Mend Leave-In Conditioner for a short time, but I'm already impressed with the early results. My hair tends to be dry, frizzy, and hard to manage—especially with heat styling and color treatments—but this product has made a noticeable difference. It goes on lightweight and doesn't leave any greasy or sticky residue, which I really appreciate. My hair feels softer, smoother, and looks more polished even on air-dry days. Detangling has also become so much easier. I can tell it's giving my hair the extra moisture it needs, and while it's early days, I'm optimistic this will become a staple in my routine. Excited to see the long-term benefits!

Olaplex's No.5 Leave-In™ Moisturize & Mend has quickly become a must-have in my haircare routine. As a stylist, I'm always on the lookout for products that deliver real results without weighing the hair down, and this leave-in does exactly that. It hydrates, detangles, and strengthens with the signature bond-building technology Olaplex is known for, all while leaving the hair soft, shiny, and frizz-free. The texture is lightweight and creamy, making it perfect for all hair types — from fine to thick or curly to straight. I love that it smooths split ends and helps protect against heat without feeling heavy or greasy. I use it on damp hair before styling, and my clients always comment on how silky their hair feels. If you're looking for a leave-in that truly repairs and revives your strands, this one is a game-changer. ***This product was provided for promotional purposes in exchange for my honest review.

Hello my name is Ashlee and I'm currently a college student/UGC creator and writing reviews as a little side hobby. I've been getting into skincare and hygiene for about 6 years from now and I do not regret it . Today I will be reviewing the product, Olaplex N5 leave in conditioner. I was very excited to try out this product because I had heard alot of good things about the brand Olaplex and its products and how they restored people's curls overtime. I personally use alot of gel and put my hair into buns a lot so my curls seem to look more loose and my hair dry as well. I love how the pump is very easy to use and squirts out alot of product so i didn't need much. The product itself did smell a bit chemically but it was light weight on my hair not thick at all. In the before picture you can see my curls weren't as defined as in the after so it definitely does define the hair and makes it so theirs not alot of frizz and my hair gets really frizzy. It does not leave any smell on the hair as well. The product by itself I wouldn't recommend though you would need something to hold your curls together as someone with 3C hair.
