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'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! "This product was provided for promotional purposes in exchange for my honest review"

Hair Type Very Curly Hair

This product was provided for promotional purposes in exchange for my honest review. I only have two major criteria and choosing my leave in creams. First for it to actually moisturize my hair second is to not weigh my hair down because I love my volume. And this product did both and I loved it. Zero irritation zero Heaviness on the scalp where it would cause build-up. The only downside I felt is that my hair wasn't moisturized until my next wash hair day but it's not a complete downside. I just haven't found a product that makes my hair feel moisturized for 4 to 5 days.

I've been using the Olaplex No. 5 Leave-In Conditioner for a few weeks now, and I can confidently say it's become a must-have in my haircare routine. The consistency is creamy but lightweight—not too thick or greasy—so it spreads easily and absorbs quickly without leaving any residue. A small amount is enough to coat my mid-length hair, making it feel instantly softer and smoother. The scent is subtle and clean, with a slightly floral touch that lingers pleasantly without being overpowering. I also really like the packaging—the bottle is compact and travel-friendly with a sleek design, and the product comes out easily. It feels high-quality, just like the product inside. It's great for all hair types, and it helps tame frizz, adds shine, and strengthens my ends. I love that it hydrates and repairs without the need to rinse. My hair feels healthier every time I use it!

A Must Have for Dry, Damaged Hair – Lightweight, Hydrating

Submitted 1 year ago

By Kristina

From Orlando, FL

Hair Type Wavy Hair

I've been using the Olaplex No.5 Leave-In Moisturize & Mend Conditioner and it's seriously one of the best additions to my haircare routine. It's super lightweight but still manages to deeply hydrate and smooth my dry, frizz-prone hair. It helps with detangling, reduces breakage, and leaves my strands feeling soft, silky, and manageable without weighing them down. I've noticed a visible difference in my hair's overall texture and shine. Plus, it smells clean and fresh, not overpowering. Whether I let my hair air dry or use heat, this product gives it the moisture and protection it needs. Definitely a game-changer for anyone dealing with damage, dryness, or dullness.
