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...

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.

After using the Olaplex No. 5 Leave-In Conditioner daily for the past week, I can confidently say it lives up to the hype. My hair feels noticeably softer and healthier—like I just left the salon every single day. The scent is incredible: clean, fresh, and long-lasting without being overpowering. It made my split ends look smoother and less noticeable, and gave my hair a silky shine that I haven't seen in months. What really stood out to me is how weightless it feels. A lot of leave-ins can feel heavy or greasy, but this one sinks right in and leaves your hair bouncy and light. It also helped with detangling, making styling so much easier and cutting my blow-dry time in half. That said, there are a couple of downsides. It's definitely on the pricier side compared to other leave-ins, so it's more of an investment. And it only works on damp hair—so you can't really refresh dry hair with it unless you re-wet your strands first. Overall, if you're looking for a product that actually treats your hair and not just masks damage, this one is worth trying—especially if you want softer, smoother, and better-smelling hair in just a few uses.

A Total Game-Changer for Damaged Hair!

Hair Type Wavy Hair

I've tried countless leave-in conditioners over the years, but the Olaplex No. 5L Leave-In Conditioner is in a league of its own. From the very first use, I noticed a huge difference in how soft, smooth, and manageable my hair felt. It completely tames frizz and flyaways, adds beautiful shine, and doesn't leave my hair feeling greasy or weighed down. I especially love that it works for all hair types—mine is color-treated and prone to dryness, and this product has helped bring it back to life. A little goes a long way, which makes the price totally worth it. I also appreciate the clean scent and the way it layers perfectly under styling products. If you're looking for something that truly strengthens and hydrates your hair, this is it. Olaplex nailed it again!
