Olaplex No. 9 Bond Protector Nourishing Hair Serum, Heat Protectant, Softens & Weightlessly Nourishes, Reduces Tangle & Static, For All Hair Types, 3.0 fl oz

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.

I’ve been using this for almost over a year now and definitely recommend it. I have thin hair and it’s helped to fix previous damage and continue to let my hair grow out healthier. The scent is nice but in my experience doesn’t last too long throughout the day. Makes my hair soft, easy to use. I do about a quarter sized pump and apply to the ends of my wet hair prior to scrunching my hair or using heat!

I purchased Olaplex No. 9 Bond Protector after my stylist used it on me, and I’m so glad I did—it’s a complete game changer! This product is fantastic because it acts as both a nourishing serum and a heat protectant in one, which makes my routine so much easier. The scent is incredible, and I’ve noticed my blowouts last longer and look smoother with less frizz. My hair feels healthier, softer, and more manageable every time I use it. Highly recommend for anyone looking to elevate their hair care routine!

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.

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!

This stuff works surprisingly well!I tested it out by putting some on my dry hair on my ends and up toward my crown, focusing on areas with fly-aways. Then I followed it with straightening my hair with a flat iron.It made my hair significantly less frizzy and sleek looking.Once straightened the product seems to hold my hair in place—like giving it a new set-point. Instead of looking like wavy hair that’s been straightened my hair just looked like it’s naturally straight. I really love that.It took little effort with my straightener and less passes to straighten it.It’s now part of my regular routine and will likely stay that way unless they stop making it.My hair is down to my waist, thick but fine, and naturally wavy. My scalp can get oily easily with products, but I didn’t notice any difference in oiliness while using this.The smell is not very noticeable. It’s like a non-offensive, clean smell. It doesn’t compete with my perfume.The consistency is like a watery gel. It almost feels like hair gel when you put it on because you can feel it dry to the hair quickly. But it doesn’t make it feel stif, crunchy, sticky, oily or anything. It feels kinda perfect, like magic.It’s a cool product, I love it and recommend it!

Worth every penny. I have odd hair, its very curly, porous and breaks easily. Its been growing out for a year and since starting olaplex I get less breakage and my hair feels healthier

I have been using Olaplex shampoo and conditioner for about 5 months now. I was looking for something to help with my dry ends and frizz while growing out my natural hair color (dark brown with small strands of white, with a naturally white stripe in the front). I read the reviews. I really love the results from the shampoo and conditioner, so I decided to try this. Washed and conditioned my hair last night, then applied Olaplex No. 9 Bond Protector Nourishing Hair Serum. I noticed the results almost immediately. My hair usually goes frizzy whether I let it dry naturally or if I blow dry it. My hair was much smoother and less frizzy and is holding my style so much better! I didn’t have to use very much hairspray at all! I would definitely recommend this to anyone. I realize that the price is steep, and that some people said that they had to use more product than the directions say. The price is steep, but if you can afford it, it is incredible. As for the amount to use, as with any hair product, the amount to be used depends on length and thickness of your hair. That is only logical. This product truly made a substantial and noticeable difference in my hair, it’s softer, shinier, smoother, less frizzy (almost completely frizz-free) and my dry ends look sooo much better!
