Very good quality
If your hair is feeling dull, frizzy, or vulnerable to heat and pollution, Olaplex No. 9 might be the rescue remedy you’ve been waiting for. This leave-in serum is designed to protect, smooth, and revive your strands — and it’s earned rave reviews across the board.🌟 What Makes It Special:• Triple-Action Formula: Combines Olaplex’s patented bond-building technology with red algae extract to strengthen hair, shield it from environmental damage, and boost shine.• Heat & Pollution Protection: Guards against heat styling up to 450°F and defends hair from pollutants and UV rays for up to 48 hours.• Lightweight & Non-Greasy: Unlike many serums, it doesn’t weigh hair down or leave it oily — even on fine strands.• Versatile Use: Works beautifully whether you air dry, blow dry, or style with hot tools. Some users even apply it to dry hair between washes for added smoothness.

Healthy, Stronger Hair from the First Use
“I’ve been using this Olaplex nourishing serum for a few weeks now, and I’m really impressed. My hair feels softer, smoother and much more manageable. It reduced frizz and added natural shine without weighing my hair down or making it greasy. The scent is pleasant and subtle, and a little amount goes a long way. Overall excellent product. I’ll definitely keep using it

Great product
I use this product almost every time after I towel dry my hair. It has become an essential part of my hair care routine, providing me with the perfect balance of moisture and hold. If I’m planning on wearing my curls, which are of the 2C-3A hair type, I’ll pair this product with the ouai curl cream. Together, they leave my hair so smooth and frizz-free, enhancing the natural beauty of my curls. The combination is incredibly effective, and I often receive compliments on how defined and healthy my curls look.Sometimes, I’ll just use this product without the curl cream, and it works really well if I’m just straightening my hair as well. The product has a unique ability to smooth out my hair, reducing the need for excessive heat styling. It provides a sleek finish that lasts throughout the day, keeping my hair looking fresh and polished.Overall, it’s a very versatile product, and it’s a must-have in all of my hair routines. Whether I’m curling or straightening, it consistently delivers great results. I highly recommend this product to anyone looking to improve the quality and manageability of their hair. It’s a game-changer and has definitely earned its place in my beauty arsenal.

Lightweight, Pleasant Scent & Heat Protection.
After using this serum for a few weeks, I’m really impressed. My hair was often stressed from heat styling and colour treatments, but with this product I notice it feels stronger, smoother and less frizzy. I apply it on damp hair from mid‑lengths to ends, before styling, and it doesn’t weigh my hair down. It also leaves a subtle, pleasant scent that lasts.

Great heat protection with a lightweight feel
I use heat tools often , and this serum has been a game- changer. It protects, tames frizz, and adds shine without making my hair greasy . The scent is nice too. Only reason i give 4 stars is the price – but the quality justifies it!

Protects my hair and leaves it soft
This is truly a great product. It protects my hair from heat damage and leaves it feeling softer than before I purchased it. I wish it was a few dollars cheaper, but will hopefully grab it on a sale the next time.

Saved my curly hair
Only thing that keeps my curly hair healthy! For someone that has curly hair but loves heat, this really helps my hair stay soft, smell good but still curl after!

Helps with dry frizzy hair and easy to apply
Great for aging dry hair. As I age my hair is more grey and that hair is stiff and dry. I’ve never been someone who likes to fuss with hair products or take the step to add conditioner during my showers. So this works great. You put a small amount on your hand, rub it into your hair after you get out of the shower, and it doesn’t leave it feeling greasy or with residue. I can “feel” hair product residue with most mousses, etc so this is a plus. It calms my hair down so it doesn’t frizz, which I never had a problem with until I got old. LOL

I bleached my hair and went to cut the ends. I still have some hair remaining that was bleached so I really don’t want my ends to end up being so dry again. I’ve only used this twice and used one pump on my hair after towel drying it. And when I either air dry or blow dry it, it leaves my hair really soft and healthy. Love it!!

Termoprotettore della linea OLAPLEX, ottima texture e dura veramente tantissimi mesi, ne basta una goccia da distribuire sui capelli, buona la profumazione! Consigliato
