Amazing!
A little bit of this product goes a long way! I first recieved a free sample of this in one of my orders and that small sample lasted so long and my hair felt so hydrated after use that I had to buy the full sized one!

Not a bad product, but I wasn't that wow-ed either.
This may work for you if you find serums are normally too dense for you and you need a lot of product on your hair or your hair is really long and there is a lot of it to cover. Because in every experience I've always found I pump just once and I have so much product left on my hands I'm forced to wash it down the sink because it is not the sort of pot you can place the excess back into. This is really frustrating for me- you only get 90mls of product in a tube. Even the No.3 and 8 have 100mls! I think that if you're going to have such a low volume for the price the least you could do Olaplex is to have a pump which doesn't appear to deposit nearly 10 times the amount I need! (My hair is shorter and though thick, it is fine). Did I see a difference? I think I did. No wow moments, overall it helped with frizz I think but I wasn't blown away. Maybe you're meant to mix it with no.6 or something (also a leave-in) but if that is the case it's not mentioned in the directions. I can think of other products I have had better results with. It didn't wreck my hair at all, it didn't weigh my hair down, it gave minimal frizz control and it was easy to apply (ignoring the excess volume!) it is extremely fluid/runny and that I wasn't expecting. I've now trained myself in the art of the half-pump so maybe I wont waste as much the creators could do would be to make it easy to use!

Best product I’ve tried
I have fine, flyaway and frizzy hair that feels course and is really hard to manage but this serum has made a big difference. My hair is noticeably softer. It’s not heavy at all on my fine hair.

Cloud 9
As a newbie to Olaplex I must admit that a small part of me was hoping the brand was overhyped for the sake of my bank balance. Sadly it is not. This serum gives me hair that would make Disney Princesses green with envy. Super silky, blindly shiny and wonderfully nourished, this serum has made my hair the fairest in the land.

My hair likes it!
I love this serum! With the help of it, the hair is combed easier, the hair becomes shiny. I also use shampoo and conditioner from the same brand. Systematically it works great!!

A game changer!
Amazing product! My hair is so soft, conditioned and shiny. It is not a styling product as it will not give volume or definition to the hair, but I never found something that my hair liked so much. It is my favorite in the olaplex line. My mum uses it as well and she said it is a game changer because our hair is usually dry and never before it felt so soft.

Unbelievably amazing
I don’t normally write reviews even if the product is great but this product has seriously made me happy and solved a problem. I have long fine hair and have been curling my hair for years without any hair spray to hold the curls, the curls would last for days before falling out. Recently my hair has stopped holding a curl and I’m told following pregnancy your hormones can change which means your hair etc can also change. I tried everything, even curling and using hair spray which kind of worked but left my hair a bit crunchy and not nice to brush out. I bought this along with Olaplex 0 and 3. I initially used these two as a treatment at the beginning of the week and then daily I’ve been using 9 and I’m blown away. My hair has gone back to normal is holding a curl again for days without any hair spray! This stuff is just amazing and I can highly recommend it
