Soft hair
Have been using for past 2 months. I use 3 pumps per half of hair on mids to ends. Have noticed an improvement in how dry my front parts feel, they feel more like normal hair strands rather than straw. Will continue to use

Definitely helps
My hair is naturally wavy / light curl when artificial heat isn’t used. This can lead to frizz and flyaways, with me susceptible to this more do when it’s been raining. I find this balm really helps to not only condition my hair, but stop it being so porous- which means it stays straighter for longer and I useless heat having to redo it on days when I’ve been outside. Highly recommend (I’m on my 4/5th bottle)

Not convinced
This definitely helps hydrate my ends, but it feels like very expensive leave in conditioner, not exactly a life changing product but decent!

Great
Love how easy this is to use and that it’s a leave in mask and not wash out. A little goes a long way and it leaves my hair so much softer and more nourished than before

Unbelievably good
This leave in mask has replaced my olaplex one. My hair feels so smooth after application and I feel it is also making long term difference

Great for bleached, damaged hair
I tried olaplex and it didn’t work for me unfortunately, but k18 seems to be making my hair so much healthier. I’ve done everything to try and repair my hair, but not seen proper results until using k18. I’ve done the 6 washes in a row and now use it every other wash alternating with a deep conditioning treatment. Makes my hair feel so soft as well!!

Mixed feelings
I have mixed feelings about this product. My hair is thin/bleached/blond and when I use it on it's own it's crazy hard to detangle my hair so I started using conditioner after using this product, it helps but overall I am not sure if I should use it at all...

Stronger, repaired hair!!
I have had bleached hair for most of my life. When I discovered Olaplex I was all in... until I found K18! I actually discovered this via an influencer but glad I did. So much less faff. Shampoo, then apply this and leave in!! That simple (leave on for 4 mins before applying any other products) I tend to use a detox shampoo. Got a bit obsessed and was using this every other wash but have reduced the frequency now to rotate with moisturising products. Definitely have seen my hair become stronger, thicker and more healthy. Worth it!!

Meh
I'm usually loathe to take the time to review a bad experience with a product, but I'm making an exception because there's so much hype around this. It makes my hair feel like straw! and it becomes hard to style. Nope, not for me.

Seems to be working
Introduced this to my routine recently and does seem to make a difference. However, I was surprised by the size of the bottle when it arrived. I don't mind paying higher price points for good products, but the size of this for the price was a bit much! I use sparingly, section my shoulder length hair intro three and use one pump on each.
