N°.9 Bond Protector™ Hair Serum | Heat Protectant & Softens, 90 mL | Improves Style Retention, and Reduces Tangels & Statics, 450°F/232°C Heat Protection & 48-hour Pollution Protection

I absolutely love Olaplex No. 9! It leaves my hair feeling soft, smooth, and healthy without weighing it down or making it feel greasy. I use it before heat styling, and it helps control frizz while giving my hair a silky, polished look. A small amount goes a long way, so the bottle lasts quite a while. I've noticed my hair feels more manageable and looks shinier since I started using it. It's become a regular part of my hair care routine, and I'll definitely keep repurchasing it. Highly recommend for anyone looking for a lightweight heat protectant that actually makes a difference.

This is the holy grail of hair products. I am in my late 40s and have thin, dry, color damaged hair. My hair has been frizzy and I could only wear a ponytail and even in that it would become a tangled rat mess. I have tried 100s of dollars in products from Keratin hair treatments, Aveda products, Nexus, Pantene, Its a 10, blowouts EVERYTHING under the sun and nothing was working. I was ready to shave my head and start over. Then I found this and read soooo many reviews and said shoot all I have to lose is more money. So for my fine, thin, color/highlighted damaged hair I got the 4/5 shampoo and conditioner, weightless nourishing mask,#3 Bond building hair and the #9 Bond Protector. My hair is now SOOOFFFTTT, not frizzy even when it is humid out (I live in the desert) so not many humid days until recently. This is all in just 3 days!!! Day one I used the Shampoo and Hair mask with already noticeable difference, Day 2 and 3 I used only the shampoo and conditioner. I started with the small bottles at $30 each and I am so far very pleased and plan on once I run out getting the larger bottles. I will tell you that you need a very very small amount of shampoo, it goes a LONG ways. The conditioner maybe a nickel size amount as it also goes a long ways. When I first used this and was done rinsing my hair, it did not feel soft and I was thinking okay I am going to not have fun brushing my wet hair and it was going to be a waste of money. Boy I was fooled. even though my hair did not feel soft and slick after conditioning, the wet brush I use as always just glided thru my hair with such ease. I was like oh okay and then once I dried it I was completely shocked at the difference the first wash alone had made. There were no tangles and the entire day my hair has been smooth, soft and manageable! I say take your chance and get this product, I hope you are as happy as I am with this. I plan on tossing every other hair product away now that this is the only thing that genuinely works for my hair in a way that I have never experienced with a hair product before.

Excellent hair condition, it leaves a very pleasant hair texture, it has a spectacular fragrance, honestly it is my first time using the olaplex line and the truth is I have been delighted and my hair much more.

I love how this looks on my hair. Reduces frizz and helps my style hold while protecting from heat. Work the money to me and a little goes a long way!

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.

Make sure you don’t put too much on the roots or at all otherwise it gets greasy even on the ends. But if you get the right amount it’s great! Definitely volume and protects. My hair went from frizzy to smooth and feeling like I’m a rich girl!

Always my go to purchase on the prime days sale. My hair feels so soft after using , helps with frizz in the mid west humidity

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!

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!!
