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...

A leave-in conditioner that leaves my hair soft and manageab

Submitted 1 month ago

By Maheliset

From Temple Texas

I'm really enjoying this OLAPLEX leave-in conditioner. I use it after washing my hair and I love how it leaves it: soft, hydrated, and so much easier to style. It's easy to apply and doesn't need rinsing. Plus, my hair feels light and beautiful, without feeling weighed down. It's definitely become a step I enjoy adding to my routine!

No-Fuss & Frizz-Free

Submitted 1 month ago

By Margarita

From FL

I've been keeping this leave-in conditioner in my bag, and it's honestly so convenient. The size is perfect for tossing in my carry-on or gym bag without taking up space, and I love that it's fragrance-free, no clashing with my perfume or other products throughout the day. A little goes a long way, so this small size actually lasts. My biggest struggle living in Florida is frizz from the humidity, and this one genuinely keeps it under control. What I love most is how easy it makes detangling and smoothing without any extra steps. I just spray it on damp or dry hair, run my fingers through, and my hair instantly feels softer and more manageable. No greasy feel, no weighing my hair down, just soft, healthy-looking strands whether I'm touching up mid-flight or refreshing my hair after the gym. My routine now: spray a light mist through mid-lengths and ends, work it in, and go. Hair stays smooth and frizz-free all day, no matter where I am.

Perfect for Heat Styling

Submitted 1 month ago

By Pushpita

From Boca Raton. FL

This leave-in conditioner is rich and moisture-heavy. Since it is so rich and heavy, I actually would not use this for day-to-day styling. Instead, it has become my go-to specifically for blowout and straightening days! It provides 450°F heat protection, which is always what I aim for whenever I am using heat tools on my hair. It leaves my hair feeling so soft, smooth, and fully protected. This is amazing for those heavy heat-styling days when you need serious protection and moisture. I received this product as a part of an educational promotion.

Bottom Line Yes, I would recommend to a friend

Good conditioner.

From Selma, NC

I have been testing this Olaplex leave-in conditioner on my hair and it is excellent. It leaves it very soft and clean, not greasy or heavy at all. It also helps with the frizz. A small amount is enough for the whole hair. I think it works very well.

Amazing Multi-tasking Product

Submitted 1 month ago

By Sarah

From DC

I received this product as part of an educational promotion and tested it for 7 days. As someone with fine, thin hair, I have to be very careful about layering too many products. Finding products that do more than one task are a game changer. I love that this gets so many things done all in one product.Not only does it mend split ends and moisturize, it includes a heat protectant as well. I apply to damp hair, focusing more on the ends, and only use 3-4 pumps since I have such fine and short hair. It feels very lightweight upon application. After my normal blow drying routine, I notice my hair appears more smooth than usual. To my surprise, this does not cause increased greasiness on my day-two hair. I am a big fan and am so excited to have this added to my routine.
