Not sure if it’s just me but I can’t get passed the texture of this felt like I was putting lube in my hair
Love Olaplex No.9
By far the best hair serum I’ve used. A little goes a long way and it leaves hair feeling soft and silky after drying.Great product
Love this product for my fine straight hair - hydrating and provides heat protection too.Lightweight, protective serum
Lightweight and a little goes a long way so it lasts for ages. I use before drying and straightening and think it offers heat protection and reduces split ends. I repurchased before I ran out!Nice but expensive
Works very well. Hair feels very soft and silky. But the packaging is deceiving as the actual product is only about 1/3 of the bottle. Expensive for how much you get. A little does go a long way though.great for blowdrying
makes the hair super soft when blowdrying - lives up to the hypeHydration and shape
Once you get the hang of it, this is great for frizzy hair. Treat it like a serum on damp hair and then lock in with some oil on your ends if you need. A tiny bit patted onto dry hair gets the flyaways and frizz behaving without weighing down waves.Very happy
Best product I have thick curly hair. My hair feels soft and manageable . The first time I used it l said wow. No other products have been as good. Very happy.Olaplex
I got this as a gift with purchase from Adore, I enjoy using this product but I hate the packaging. It constantly leaks even when I store it standing completely upright. It doesn't smell nice but, its very faint and doesn't stay for long once you use it in your hair. Mostly does what it says it does but, I can't really tell if it has done anything to repair damage to my hair though.Excellent Smoothing Serum
With my thick hair becoming frizzy after menopause & colouring not much was helping to smooth it or give it back its shine. This however has been a god send. Pricey but worth it!!Helps with frizz
Perfect for blow drying helps with frizz and leaves my hair so shinysoft tangle free hair
as a bleached blonde i get rough ends, this helps sooo much with frizz and softnessAdds shine
Wasn’t sure what to expect from 9 absolutely love it used before air drying and made my hair so shiny.Smells really nice
It is such a nice smelling product and helps styling my hair. It makes my hair feel very smoothMy go to everyday
I use this after I wash my straight asian hair, style with my curling tongs and my waves last for 2-3 days until my next wash. I get compliments on how soft and healthy my hair looks.Not for me
Not sure if it’s just me but I can’t get passed the texture of this felt like I was putting lube in my hairLove this
Received a sample of this product that I have just finished, I absolutely loved it. Its a fantastic product and worked really well for my hairLove this
I used to always use heat protectant sprays before applying heat to hair, but I now prefer this Olaplex no.9 serum after washing, before drying. It's easy and is not greasy or sticky or anything. I feel like it helps leave the hair soft and protected.Best serum
This serum brought life into my hair. It was so dull and unruly prior to using this. I finally have silky shiny hair.Lightweight hydration
I love the Olaplex no. 6 for my damaged dry blonde hair, but this is my new fave. Its lightweight texture means that my natural is defined, whereas the no.6 is a bit heavier and makes my hair flatter. Curled my hair with no hairspray, just the no.9 and the curl stayed for days, when normally I am lucky to get 12 hours.Slimy goodness
The texture of this product was a pleasant surprise!! It's super lightweight and doesn't weigh down my thin hair like cream products tend to. My main purpose for using this product is heat protection and detangling, both of which is does pretty well! The only downside is the price, so if you have unproblematic hair, I'd suggest using a more affordable leave in product. But if you have damaged hair...Read MoreFavourite serum
I love the Olaplex range and this is my favourite serum I have usedNice and light
I often find products like thus are too heavy for My fine hair, this is really good and light.Excellent!
I have fine, highlighted hair that is naturally some kind of frizzy curly but I straighten. Loving using this after each wash and my hair is looking so smooth. My ends look so smooth and freshly trimmed and I get no frizz. Very big fan. Love that it includes heat protectant, one stop shop for post wash! Going to try using it and naturally drying next wash to see what it does to my curls. I have...Read MoreLove this!
This is such an awesome product, I put it on my hair before blow drying it and my fly aways and frizziness is greatly reduced! I no longer look like I was electrocuted after blow drying. Its not heavy at all and does not make my hair greasy. I will definitely purchase this againBest one yet
I received a mini version to try in one of my orders and this is my new favourite hair product! It has solved my frizzy hair issue without making me too oily.Very good for detangling fine hair
Received it as a sample and within a week i ordered the full sized product. I have fine straight hair with blonde highlights. My hair gets really knotty after a wash. After applying a small amount of the olaplex serum on wet hair, i found it was much easier to brush it, resulting in less damage / fewer hair on the brush which is a nightmare for fined hair girls... I normally blow dry my hair for ...Read MoreLove olaplex
I have both 6s.. this one is more serum and watery the other is thicker. I think the other works better I dont think there is a big difference with this oneLightweight
Love the consistency spreads really well into the hairLove it
I have dry hair and it's rare to find hair serum that I like. I received this serum as sample and I just love it very much, more than the serum that I've been using for years. It makes my hair soft, hydrated and not greasy at all. I will definitely buy one soon.Take my money
It's so good. It truly is. I've got super fine bleached hair and any excess amount of moisture sends it over the edge. It's goes limp, greasy and knots/ dreads. For the record I do use the rest of the olaplex range except for 0 and 8 very sparely. One pump of this serum on shoulder length hair and it's soft, smooth, and it feels like I have thicker hair. What I truly love about it is that it is cl...Read MoreNew holy grail!
I've been using this before blowdrying and styling on wet hair and can see the difference it makes instantly. My hair has way more volume, almost no frizz and is so so smooth. The texture is also really lovely and not sticky in the slightest. Has a really lovely, fresh smell and doesn't weigh down or add oil to my fine hair (I had concerns that it would). Loving it and would absolutely recommend!
