Sleek hair

I use this serum before blow drying and I find it gives the best results when going for a straight / sleek look. My hair looks so shiny and smooth, staying soft for days. I have tried curling also but had been less impressed, the curls have dropped more than when I’ve used other blow dry products.

Expensive but works

This serum is so lightweight and gives my fine hair a lot of extra volume when I use it before blowdrying. It is expensive but the bottle lasts quite a long time as you don't have to use much at all. It seems to protect well against heat and smells very inoffensive.

Works Amazingly Well

I love No 9. It leaves my hair smooth and shiny. It seems to control frizz better than other things I have tried. It’s the only Olaplex product I use, but am so happy that my stylist also uses the No 1 and No 2 when he colours my hair. It just feels so much better and No 9 is the cherry on the top.

OK but not brilliant

I'd had this product for a long time and had thought it was good. But frustrations with the packaging (which leaked every time I tried to travel with the bottle) and having since found a better Olaplex product which seems to work much better for my hair, has meant I will be swapping this one out.

Good for detangling and shine

I have long hair that has a tendency to tangle once it gets beyond a certain length. This olaplex product is great for that reason, and it also provides shine. I only use when I'm drying my hair without a hairdryer, it protects without weighing the hair down.

Olaplex

Best heat protectant in the market. It’s fragrance free which helps if you’re sensitive like I am.
