OLAPLEX N°.9 Bond Protector™ Hair Serum | Heat Protectant & Softens, 90 mL

I was struggling with dull, heat-damaged ends and relentless frizz, but Olaplex No. 9 Bond Protector has completely turned things around! This weightless serum acts as an invisible shield against daily pollution and heat styling, leaving my hair noticeably silkier, bouncier, and remarkably soft. It adds a healthy, glossy shine without ever weighing my fine hair down or making it greasy. Applying just a tiny pump to damp hair before blow drying instantly smoothes flyaways, detangles knots, and holds my style all day. Plus, it’s amazing that Amazon carries the entire Olaplex lineup from the iconic No. 3 treatment to the No. 4 and 5 wash duo, No. 6 leave in cream, and No. 7 bonding oil. Building a full, salon quality routine at home has never been easier. I will definitely keep repurchasing!

This hair serum is really lovely. It really coats the hair and leaves it very soft and sleek and frizz free.

Amazing product.. after having my hair highlighted this is working amazing on my hair!

Easy to use

I love this hair serum so much! I always apply it throughout my damp hair after I shower before I blow dry and it ensures that my hair is silky and shiny and frizz-free. I have used multiple bottles because I love the effect on my hair.

Almost finished with it and my hair is always like silk after I use it, it's a repurchase for me

My hair feels much less dry at the ends since I started using this. Exactly what I needed

Great

تحت التجربة

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!!

Bad may be not the original

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

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.
