No more knotted hair!
I have been looking for a serum for months now but never took the plunge to buy one. I read reviews on this and thought I would try. It’s amazing! After one use of the serum my hair (after three days of not washing it) still has smooth ends. I really suffered from tangles and knotted hair but this has really helped. It’s also helps as brushing isn't so sore.

Another Fab Olaplex Product
Having loved the rest of the Olaplex range, the number 9 did not disappoint. It has a lovely texture to it (not greasy) and leaves my hair feeling smooth and healthy. I don't use many products on my hair but this is a must!

Love!
I love Olaplex products, and I'm massively impressed by the No.9! I don't colour my hair, but I do use a lot of heat on it with straightening, blow drying and curling. The No.9 has helped with healthy appearance of my hair, and my hair is left feeling so soft and nourished - food for the hair!

Disappointed
I have most of the olaplex range but really excited to see a serum. I thought it would sink in and feel like silk combing it through towel dried hair but it didn’t.. I had to add an oil. Not impressed.

Not disappointed!
This is the first product I've used from Olaplex and I'm massively impressed! I don't colour my hair at all but do use a lot of heat on it with blow drying and straightening. The No.9 has helped restore the bounce and healthy appearance of my hair after just 1 use. My hair feels amazing!

Love that this is a heat protector that I don’t have to spray on my dry hair, leaves my hair feeling so soft and shiny.

LOVE
Can always rely on Olaplex for a fab product! My hair feels silky smooth and shiny after just one use. This seemed to help with my frizz too. Would definitely recommend trying this one.

Love this!!
Love this!! I have very fine, greasy bleached hair and it's very easy for products to weigh it down and make it greasier quicker, however, this is not the case for No.9! Its so lightweight, and it has left my hair feeling smooth and looking shiny (not an easy task with bleached blonde hair). It has a very subtle smell which I love. I use this before I blowdry and then pair it with No.6 after my hair is dry for extra smoothness. I will be repurchasing!
