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...

Light and Awesome Moisture

If you're someone who battles dry, frizzy, or damaged hair, Olaplex's newest launch — the No.5 Leave-In Moisturize & Mend Leave-In Conditioner — this may just become your new holy grail. Packed with thier usual and original bond-building science and rich conditioning agents, this product takes leave-in care to a whole new level. The Avocado & Fermented Green Tea Oils: are awesome natural emollients that nourish and add softness without greasiness. From the first application, this leave-in made my hair feel silkier and easier to manage, especially on my ends which usually feel dry and brittle. It has a light, creamy texture that melts into the hair — no greasiness, no crunch, no residue. My hair was even shinier. After blow-drying, I noticed:Less frizz, Smoother texture, Ends looked healthier, A glossy, salon-finish look. Plus, it smells subtly clean — nothing overpowering, just fresh and elevated.

I've got fine straight short hair and I usually get frizz so I have to use leave-in.  This Leave-in Conditioner provides instant results and continuous repair and protection from cortex to cuticle. I see less split ends and my hair is visibly healthier after one use. This leave-in hydrates dry hair and continuously repairs and prevents styling damage. As I know, patented OLAPLEX Bond Technology Strengthens hair and repairs damage on a molecular level by rebuilding the disulfide bonds that give hair its strength and I really see that it works! It's got a blend of Amino Acids, Squalane, Ximenia Oil, Panthenol, and Glycerin that replenishes moisturizing lipids, weightlessly conditions, detangles, and adds shine without leaving a film on strands. This product was provided for promotional purposes in exchange for my honest review.

My hair has never felt this soft and healthy!

I've been hearing so much about Olaplex No.6 and finally decided to give it a try — and I'm honestly blown away. From the very first use, I noticed a difference: my hair became smoother, shinier, and so much easier to brush through. It tames frizz perfectly without weighing the hair down or making it greasy. What I love most is how lightweight it feels — it absorbs quickly and leaves no residue, just silky softness. I apply a small amount to damp hair, and it instantly makes my hair look healthier and more polished. Perfect for air-drying or styling. If you're dealing with dryness, damage, or frizz, this product is a game changer. Highly recommend!
