Another amazing product from Olaplex

I am a big fan of the Olaplex range I use all of their products and they have been a game changer for my hair. I have fine hair and I have balayage done regularly which was making my hair dry and snapping at the ends. Since using the range my hair looks and feels healthy and the addition of the serum is a lovely way to finish my routine, extra bonus a little goes a long way

Well...such a disappointing product.

Hmm...I using Olaplex no.6 and no.7 so far.And I receive this no.9 and I expected and used it, and then my hair going bad.This product slimy texture, and I used on wet hair, when I first applied it, it had a mysterious texture on my hair.However, after that, my hair became sticky, my weakened hair stuck to my hand, and my hair was cut.You know no.6 no.7 is enough to use.I wish Olaplex need make no.6 no7 already mixed product.

Another excellent one

I have used this twice now and it is such a lovely product, it has made my hair soft and full. I love that it adds some extra heat protection for when I do my blow dry, I definitely recommend this Olpalex product as it doesn't disappoint.

Absolute must have for frizzy hair!

Have only just tried this for the first time and I am really impressed. I have been using Olaplex products for a while now - some of them better than others and I have been using the oil for a while which I love but decided to give this new product a try! Used it on towel dried hair and then blow dried my hair and it definitely felt soft and smooth. I also noticed that after I applied it and before I started drying - hair was drying naturally quite smoothly and not crispy like some products can make your hair react...I suffer with quite frizzy hair so I would definitely recommend this and not a bad price either!

Not sure

I love everything Olaplex and own all the other products too, so I really wanted to try this. I've used this for the past couple of weeks now and I guess I don't really feel like it's been money well spent. I have bleach damaged hair that's dry, prone to breakage and my ends tangle easily (especially the hair right down the back of my neck if I work up a bit of a sweat) I love the no. 6 and no. 7 after washing and conditioning as they help detangle and make my hair feel so nourished and soft, I thought maybe I could swap them out for this serum but nah. It smells amazing, but I haven't really noticed it does anything special for me. It doesn't help detangle, it doesn't feel nourishing (have started applying 6 and 7 after this now because I couldn't even get through my hair with a brush with just the serum applied) so to me it just feels like a lovely smelling heat protectant. Maybe over time it could make a difference, but I'm not sure I'd be quick to repurchase this. It's a gel like texture and it is very light weight, so if that's something you're looking for (as opposed to the no. 6), then this might be for you.

Silky soft hair

I've wanted to try this brand for so long and decided to buy this serum as my first product. Smells really nice not too strong either. My hair definitely feels a lot silkier from using this. A little goes a long way. The size is better than what I expected money wise

Olaplex is a wonderful brand for hair products, and this serum is absolutely wonderful. It leaves hair super soft and yet full of body.
