N°9 Bond Protector - Pflegendes Haarserum

Excellent product

Received as a gift for purchase of 4 & 5. Best product I’ve used for my curly frizzy hair

Good one

Great heat protector, doesn’t weigh hair down. Tames frizz *some*. Texture is a bit slimy.

My favorite Olaplex leave in product. I have very dry scalp and hair so I use it after leave in conditioner. There is a noticeable difference in my hair when I run out of this product and don't use it in my routine. It greatly improves manageability, shine, and frizz for my hair.

Miracle!!

I received this as a gift with purchase. I was skeptical since I have thin straight hair. I decided to try any way and it is a miracle. I use it on semi dry hair, 1 pump, before using my hot brush. This adds shine and stops frizz even in humidity. Does not weigh my hair down! I’ll repurchase!!

Helped me grow out my hair

I started using this product after cutting my hair. I have noticed fewer split ends and fairy knots in my hair. I have been able to grow my hair longer because there are fewer split ends and less breakage.

I like this product. It protects my hair from heat and keep it smoother and nice. It smells good. I have curly thick hair.

After just one use, I noticed a remarkable difference compared to other products in this category. My friends couldn’t stop asking, 'What did you do to your hair?' My answer is simple: I discovered this amazing serum!

Terrible

Bought it, used it as a heat protectant and legit burned my hair. Curly hair style too so thanks(: never will be buying this. It was my first time too

A must-have for your daily boost of shine to hair

I use this with the No.6 Olaplex and it gives a beautiful natural shine to the hair.

Great product, use it almost 4 times a week . Texture is so good

Not good for your hair, the whole brand is horrib

I say if you love your hair, don’t use any olaplex brands. Absolutely horrible for your hair. Over priced split ends in a bottle. Do your research ladies, olaplex is NOT a good brand for you hair.
