What It Is

A multi-benefit healthy hair serum, powered by OLAPLEX® technology. OLAPLEX® No. 9 Bond Protector Nourishing Hair Serum is a silicone free, weightless, antioxidant-rich serum that enhances any hair routine to protect & perfect all hair types and textures.

What It Does

Pollution damages our hair everyday, leaving it dull, lifeless, difficult to style and ultimately resulting in broken bonds. No.9 is packed with antioxidants to neutralize free radicals, act as a shield against pollution, guard the hair from breakage and protect against heat styling.

Apply a small amount to damp, towel-dried hair, working upward from ends to roots. Add more as needed. Air-dry for soft texture. Blow-dry for a smooth finish. Diffuse for waves or curts. Scan the QR code for education and videos by hair type & texture.

Rated 4 out of 5 by from finally tried I finally tried the serum, I love how it makes my hair feel, I was just sad it wasn’t also a heat protectant. I thought it was.

Rated 5 out of 5 by from Think of it like a glaze...... This one grew on me. I prefer to use it on finer hair or short hair for blow outs.

Rated 5 out of 5 by from Styling Products by Olaplex? Say less. Great serum. I apply 2-4 pumps after a leave-in creme & before hair oils when styling my blowout clients & my own hair, of course. Obsessed with the entire Olaplex line

Rated 5 out of 5 by from Amazing This serum is absolutely amazing! Being a bleached blonde for many years, I have tried so many products trying to find one that made my hair feel and look healthy again. This is it folks. My hair is unbelievably soft again and not weighed down by product. I have already ordered two more bottles!

Rated 1 out of 5 by from Not what expected This product didn't perform at all as advertised. In fact, my hair looks better after using nothing than it did after using this product. Very disappointed.

Rated 5 out of 5 by from game changer I'm a giant sceptic when it comes to propaganda pushed miracle hair products, but this takes the prize! It makes dry course texture, feeling like virgin hair. I sell a ton of this serum. If I'm doing a dry cut on long hair that is full of static, I will put a little in my hand and run it through and it takes all the static away. Amazing stuff!! I love Olaplex products. But this is my favorite.

Rated 5 out of 5 by from Highly recommend My hair is bad shape.It is dry and brittle and no life to it.I try so many products and some do nothing and others are just ok.I decided to give this a try and am so glad I did.I didn't get to try it on wet hair yet (which I think will yield even better results) I used a pea size on dry hair and then used a flat iron.My is smooth and it feels so much healthier.Moisturizing products can be too heavy and volumizing are drying but this is perfect.I feel as it also puts some life and body in my hair.IMO one of the best products I have ever tried.

Rated 5 out of 5 by from Love Love Love This product is so good! It’s great because it’s not heavy at all and a little goes a long way. Hair looks and feels healthier after each use. I struggle to find products that aren’t heavy on my fine hair but this is the best. Buy it!
