So my first mistake was not buying this from Cult Beauty (I didn’t know they done it) so got it from a well know website and it was a tenner more! Anyway about this fantastic product. I have thick, bleached long hair which requires a lot of TLC. I was really apprehensive about not conditioning (as recommended) as my hair is so so dry but followed the instructions and WOW. This is game changing. My hair after just one use was so soft, not frizzy and looked so good.  I really can not recommend this enough. Bit pricey but saving on conditioner and I would actually pay double.Â

Is this Magic?!
I am OBSESSED! I have very long 2A natural hair with heat damage at my ends so I could not wait to try this product. I tend to like fuss-free routines and don't love to have lots of different steps when I wash my hair so this was perfect as all I have to do was apply it on slightly wet, clean hair and wait for 4 minutes. I have long hair and have to use about 5 pumps to cover the whole area. After waiting a few minutes I dried my hair as usual and applied a little oil to finish off and OMG! My hair looks and feels so much healthier (I had 2 applications so far). I am in love!

It's a wow moment!
I am not normally a reviewer, but this one I am leaving without even getting an email request.My hair is normally a bit dry and limp, hard to manage and fine, but...I used this product for the first time today after going swimming and the result is incredible! My hair is soft, full and tangle free but not weighed down with product or left with that 'crunchy' feeling leave in product can give. I followed the instructions exactly and whilst it was weird not to use conditioner it really did all it claims to do in just one wash and I am looking forward to seeing what further use will do for me.Here's the downside though - it's really expensive. It won't be a main stay in my collection because I simply cannot afford it and that is a real shame. However, if you don't have the same budgetary restraints then give this a go and enjoy the miraculous results

Life changing!
This has been a gamechanger for my hair! I have long, thick, curly hair that over the past few years has gone through coloring, lightening and using heat styling tools (at home and permanently straightening treatments). I've tried using hair masks religiously which have worked on my hair....but always needing to wait at least 20mins before washing it out, and then conditioning after, I find the process just too time consuming for my very low maintenance self. I was kindly given this product to try by the brand and I am not joking when I say that after just three (3) uses I can see a massive difference. My hair feels softer, looks shinier, and I'm not lying when I say NO FRIZZ - even when being rained on! This has now got a permanent place in my haircare routine!

New hair who's this..
I can be quite lazy with my haircare so I prefer to opt for fuss-free products that don’t require ‘leave in’ times or pre-treatments. K18 is straightforward to use and it works wonders! I like that I can apply to damp hair without having to rinse it off afterwards – super easy to include in your routine and it leaves your hair feeling so soft.

GAMECHANGER
I was very kindly sent this to trial from the brand and oh my, I have not been this blown away by haircare in YEARS. To give some context, my hair is naturally very dark brown and i've been bleaching it white blonde for over 10 years so you can imagine how dry and chemically damaged it is. I was incredibly hesitant about using the mask without conditioner, especially with the mask being so lightweight. But the mask left my hair unbelievably soft after just 4 minutes! I would go so far to say this is a miracle product for me - visibly reversing damage from first use. This is a new permanent addition to my haircare routine!

WOW
This blows my beloved Olaplex out of the water! My hair is so soft, and incredibly shiny - I can’t stop looking at my hair. I get the best results by washing twice with shampoo, then towel drying my hair and using this (I split into sections and lather in my hands so it turns white and I can see where I’m placing it). I wait 4 minutes and go back in with my conditioner as I am prone to tangles. This is a game changer!

Need bigger bottle + can condition
Saved my hair which was literally melting from bleach and snapping off constantly! But my hair is to my waist and thick so I go through this more of the product even though a little goes a long way so need a bigger bottle I have emailed k18 and you can use conditioner as normal after having K18 on your hair 4 minutes or over so if you have very dry frizzy hair K18 does wonders but you can apply a leave in conditioner or condition as normal after you have left it on for 4 minutes!Â

Wow
I never leave reviews but I’m so impressed with this. I have bleached hair, that is coarse and always on the drier side. I religiously use Olaplex and have tried very bond building and hydrating product imaginable but I’ve never seen such a marked difference in my hair as I have with K18. It feels wonderful, looks healthy and shiny and has wonderful movement. I’m honestly so impressed. Â
