N9 Bond Protector - Nourishing Hair Serum

Silk and Shine

LOVE this product! I have oily hair but a little on the ends goes a long way for sleek hair with extra shine!

Noticeable difference added way more shine

I bought this from my hair salon and have been using it after all my washes. Before I even got halfway through the bottle, my hair was noticeably shinier. It's not too heavy for my thin, dry hair. I still need to find another product or two to help with dryness on the ends. But this does make a difference and help.

best heat protection

this is the second time I buy this. It's not a wonder product, but this in combination with good conditioner, hair masks, and styling. just seals the deal. it smells nice leaves no residue and I can feel how nourishing it is and how it helped my hair alongside other champions like the briogeo don't despair repair conditioner. frizzy for all my life, no more!

OMG

I am a new Olaplex gal. I have never in my life been more blown away by a hair care line! This stuff is the Holy Grail. I don't know if it's the number nine followed by the number six and seven mixed together in my hands (a little trick I learned from texting with an Olaplex expert) which is another awesome feature that this company offers. But my hair that was NOTICABLY DAMAGED like three weeks ago (I mean I wasn't styling or blowdrying because of how crazy it looked) is now polished, looks fantastic and I am actually happy with my hair. I am seriously in shock of what this stuff does to my hair! I can't say enough good things about this company!!!!!! I DO KNOW THAT I WILL NEVER EVER EVER USE ANYTHING ELSE ON MY HAIR. And that is something that I have never ever said before.

Worst Hair Product

Worst hair product I have ever used. For the first time in my life, I experienced hair breakage using this. The formula was also very sticky. It also made my hair frizzy. It made my ends looks very brittle. It was a mess. Biosilk is way better than this.

My favorite

I just got this recently and LOVE it. you can use it wet or dry and it makes you hair so smooth. defrizzes and nourishes. its not sticky or crunchy when dries. holds for days and doesnt get that leave in ickyness. helps with fly aways and all the stuff.

I’ve been using this for two years now and don’t ever plan on changing brands unless something drastic happens. My hair is much thicker and healthier. I use all of olaplexs products together and absolutely love it

Didn’t do much to my hair

My hair is dyed and I thought this serum would help a bit with making it softer and shinier. It’s not a bad product, but it didn’t do much for my hair and it is pretty expensive.

Save my Hair!

Olapex save my hair. No. 9, along with the rest, helped me grow my hair back

Sticky and made my hair more tangled!!

It’s ironic that this is a bond nourishing hair serum - no matter how little I used (on my very long hair, which there is a lot of), it was like glue and I swear, large tufts of my hair were falling out as I combed it. Do not buy!!!!

Made my hair greasy

Did nothing but make my hair super greasy and like I hadn’t washed it for weeks.

No Silicones!

I switched to this from Olaplex 6 because I’m getting rid of all products with dimethicone. I was getting too much build up from using products with silicones (it’s real, I could see small white pieces that looked like dried glue along my hair strands after washing) and I vowed no more silicones. The active ingredient (bis…) is high in the ingredient deck so that’s also good.
