My hair feels super soft
Got this as a free gift during black Friday and I have to say I love this! I put this on before blowdrying my hair and it leaves my hair so soft! I got a balayage done and my hair was so damaged after as my hair is super thin and fine. But now it is so soft and I have no tangles trying to run my comb through my hair. I have also been using this with the No 3 Hair Perfector and it is such a good combo. I highly recommend.

Wouldn’t buy again
I really wanted to love this, and I love all of the OlaPlex products! But unfortunately, this just doesn’t make the cut for me, the texture of this gel in my hair is really strange, and it’s hard to distribute. I don’t find it makes much of a difference and I already use the number six and the hair oil. Save your money.

Worth the money
Great product. I purchased an Olaplax set which didn’t include no.9. After being sent a tester I decided to buy it. In the whole olaplex range no.9 is my favourite!

Love Love Love
A product I wouldn’t be without…has made a big difference to my hair & keeps it smoother & tidier & really helps towards condition after using heated tools. A little goes a long way & doesn’t add any weight to my hair. A product I wouldn’t be without, would highly recommend.

Love this product
First time I’ve bought this product and would buy it again and again… I use it on my wet hair before drying and styling to protect it and then a smaller bit on the ends after drying and styling and it’s never been shinier.

Not my favourite Olaplex
This serum is nice but I can’t tell the effect it’s had on my hair like I can with no. 6 & 7. It helps lock in moisture but I would probably stick to other treatments I’ve used before over this.

Good serum
This is a good serum - I use it in conjunction with the bonding oil and it does seem to tame my hair down. I also use the shampoo & conditioner on occasional washes so not sure it would be as good on its own. It is expensive along with the other items so unfortunately can’t afford to use the set together every wash!
