WOW!!!
As a very loyal Olaplex customer and until recently not finding anything better for my hair,… I was very sceptical. So bought the 15ml to try. What can I say,… washing on not conditioning is a scary concept! Lol! BUT! After one use, I can say this stuff is nothing short of miraculous!! I’ve always struggled to control the frizz and hydrate my hair, not now! For the first time since I can remember I used 3! Just 3 products for sleek, shiny and MUCH stronger hair! Shampo, K18 and heat spray. The conditioning power of this might even having me ditching the straighteners, as after drying with my dyson, I had no frizz! Just wow! I NEVER want to be without this!!!Â

WOW super impressed!
Used for first time today, my hair has improved in recent months after going silicone free with MVC 3MI but as I colour and heat style frequently there’s always room for improvement. I’m blown away by the result after just one use, I am sure  the fact I have no silicone in my hair at all has helped K18 penetrate really well.  I have washed, no conditioner and applied K18, nothing else. Blow dry with my Dyson and my hair is soft, shiny and swishy! Super product and they say it’s gets better after few uses so cannot wait to experience full benefits. Do I recommend? YES!!Â

K-18 leave in mask
By buying this product I was hoping much more. But when I tried got very upset, spend so much money and I didn't see any difference to my hair. Not recommended.

4 min Happy Hair Wonder
For a lazy, sweaty dirty hair girl like myself who really puts her hair through the trials of life. This is my hero for smooth shiny and feels like fresh hair vibes. The no conditioner step is also a huge time saver especially for those mid week time sensitive washes. I am obsessed with how your hair gets healthier and shinier the more times you use it. Just think smooth brushing for days after use, joyous! Plus for someone who usually gets quite an oily scalp this has added life and health and moisture back into my hair without weighing it down or increasing oil production. So all in all 4 minutes for healthy happy hair I am stoked!

Good maintenance for great hair.
I am always up for trying a new leave-in treatment and this one has really surpassed my expectations. I've seen the hype since it launched stateside and am so pleased that I invested. My fine limp hair feels strengthened without being weighed down and I can use it a couple of times a week as a treat. My locks seem happy and so am I!

A hair care game changer for reversing damage.
Clinically proven to reverse hair damage in 4 minutes...I am here for this. My bleached, coloured hair needs all the help it can get and after one use my hair felt softer, smoother and stronger. I know this sounds unbelievable but It gets even more bananas - my fine, straight, pretty boring hair had an unusual weighty bounce to it which is something I haven't experienced in a long time. The suggested usage is 4-6 consecutive washes followed by every 3-4 washes to maintain hair strength. It might be magic or the patent K-18Peptide that is reconnecting my broken keratin chains, either way this is exciting and I can't wait to see the results after continued use.

Next-gen in Haircare
Welcome to your new cult obsession, the next-generation in haircare!This leave-in conditioner felt like it was working from the first time I used it. I have fine, dry, mature hair, recently ravaged by COVID and its growing through weakly at the moment. I need to strengthen that regrowth to ensure it ends up as long thicker hair in a few month's time so this really appealed to me. It's been proven to strengthen the hair core over time, I've been using it for a month so time will tell for that side. What I didn't expect from such a pumped up formula is it also leaves my somewhat depleted mop soft and brilliantly VOLUMISED. I only need a pump, for longer, curly or textured hair I'd say 2-3 max. It doesn't weight hair down. The first really new innovation I've seen in haircare since Virtue and Olaplex, dropping first, and exclusively to Cult Beauty (of course)!!

Best hair mask ever
Bought the 15 ml version and now I’m obsessed. A little goes a long way, and read the manual it is important!! The results are even better that way. I don’t colour my hair, but I did have very dull hair. My hair is wavy but somehow the curls didn’t come out anymore. When I used this I got my curls back! Holy grail. Bought the 150 ml version after that.
