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...

Restore My Damaged, Split End

Submitted 1 year ago

By Paloma

From Dallas, TX

Hair Type Wavy Hair

I been using Olaplex No. 5 Leave-In for a few weeks now, and I can confidently say it's been a game changer for my damaged hair. My ends were dry, brittle, and split from heat styling and years of coloring, and this leave-in has helped me get back on track to healthy, softer hair. What I really love is that it's more than just a conditioner, its packed with Bond Building Technology, plus ingredients like jojoba seed oil, green tea extract, and niacinamide, which all work together to strengthen, hydrate, and protect. I apply it after I shower while my hair is still damp, focusing mostly on my mid-lengths and ends, and it instantly makes my hair feel smoother and easier to detangle. I've noticed my hair looks shinier, feels stronger, and my split ends are less noticeable.If I had one complaint, it's the scent. It's not a bad smell at all, it's fresh and salon-like but to me, it's just a bit too strong. I personally prefer fragrance-free products, so I wish they offered a lighter or unscented version.This product was provided for promotional purposes in exchange for my honest review.

I have long straight hair. I was applying No 6 and my hair looked healthy and shiny but when I sow this new product, I decide to tru it, and this product made my hair look super dry and with a lot of freez. I had to return it and go back with No 6

Lucious, Lavish & Luminous!!

Hair Type Wavy Hair

Lucious, Lavish & Luminous. The best way to describe how my hair looks and feels after I started using OLAPLEX No.5L Moisture & Mend Leave-in Conditioner. I have a lot of thick hair. (So much, that if I want to keep it long. I have to have a 2 inch undercut) After my first use, I saw an immediate change. My hair felt silky and in better health/shape. Fast forward a week. My hair feels stronger. Any possibility of split ends, completely GONE! I love the light weight feel and texture of the product. Not to mention that OLAPLEX No.5L Moisture & Mend Leave-in Conditioner also is a Heat Protectant. On those days where it is extra dry and/or windy here in Wyoming. I take half a pump of the Leave-in Conditioner and on dry hair, smooth my ends. Soo fabulous!! Plus, I know come winter. My hair won't suffer from the wind & cold. I love the design of the bottle as well. Smart, innovative!!

Promising Start – Hair Feels Healthier Already!

Submitted 1 year ago

By Tori

From Chicago

Hair Type Wavy Hair

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!
