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...

It moisturizing for my hair

I felt quite in love with the leaving in conditioner. I always heat and style my hair, so use normal and leave in conditioner all the time. This one has a pleasant smell. The conditioner left my hair shiny and a bit softer. However, if you don't blow dry it completely, the hair with conditioner will clump up.

A Game-Changer for Healthier, Stronger Hair

- [ ] Olaplex No. 5 Bond leave-in Conditioner has completely transformed the way my hair looks and feels. From the moment it touches your strands, you can tell this isn't your average conditioner. It has a rich, creamy texture that instantly coats and nourishes without feeling greasy or heavy. - [ ] What truly sets this conditioner apart is how deeply restorative it is. After rinsing, my hair feels incredibly soft, silky, and smooth—like each strand has been sealed and strengthened from the inside out. It also makes detangling effortless and leaves my ends looking noticeably healthier and less prone to frizz or dryness. - [ ] Over time, I've seen a significant improvement in the overall manageability and resilience of my hair. It feels stronger, looks shinier, and holds moisture so much better. The scent is light and clean—just enough to elevate the experience without overwhelming your senses. - [ ] This is more than just a conditioner—it's a treatment that works with your hair on a deeper level. If you're looking to invest in the long-term health and beauty of your hair, Olaplex No. 5 is absolutely worth it. A true staple in any serious haircare routine.

Brings My Hair To Life!

Hair Type Very Curly Hair

I've been using Olaplex for years so it was no surprise that the No.5 did wonders on my hair! I've been dealing with dry hair, especially since I live in a humid climate so this product really gives my hair life! It's creamy and moisturizing, yet still lightweight with no greasy residue. It helps make my scalp and strands of hair hydrated, controls the frizz and overall softer. I also love the multi use of being able to use it whether I'm wearing my natural curls and air drying my hair or blow drying my hair to straighten my hair. Even when I'm wearing a slick back bun, I noticed how shiny my hair is.Overall, I love this product and it's truly a staple in my hair routine. A little product goes a long way so it's truly worth the investment. 10/10 recommend!

"This product was provided for promotional purposes in exchange for my honest review" I'm a huge fan of Olaplex and use many of their products, so I was excited to try the No.5 Bond Maintenance Leave-In Conditioner—and it did not disappoint! It instantly reminded me of the No.8 mask with its smoothing, hydrating feel, but in a lighter, more everyday formula. It adds beautiful shine, defines my hair without any heaviness, and keeps it feeling soft and healthy. I especially love how it doesn't weigh down my strands or leave any residue. The scent is that clean, signature Olaplex fragrance I've come to love—subtle but fresh and luxe. This has quickly become a staple in my routine and pairs perfectly with the rest of the Olaplex line. Highly recommend if you're looking for weightless moisture and definition!
