Great with K18 mask
I purchased this shampoo to use with the K18 mask as I wanted to ensure the mask would be able to penetrate my hair to allow it to work properly. I have only ever used it with the mask and find it works great with it. The mask has to applied to shampooed only hair and this shampoo preps the hair nicely for it. As a shampoo it’s an effective cleanser leaves my hair clean and not as dry as many shampoos but I currently have extremely dry hair. The mask is definitely the stand out product but I think the shampoo does help prepare the hair for it to work, but it’s not a necessity.

Great Product
I bought a small size of K18 recently after hearing all the positive reviews and after it lived up to the hype i also bought the shampoos. This is fantastic - my hair was smooth, shiny and moisturized. It seems to hydrate well as my hair was very shiny and smooth. I have very long and thick hair but this shampoo and the conditioner worked well together. Absolutely love it - great find!

A Good all rounder
I bought this as I as I already had the detox shampoo and mask. I've found that using this and the detox( once a week) followed by the mask, my hair has found a new lease of life. I had major surgery a month ago and my hair felt dreadful afterwards, so I set about using the K18 range religiously exactly as instructed and it has worked wonders. This is not a cheap range, but I invested in it because I care about my hair. My hair is long, fine and coloured and prone to tangling. It didn't leave any residue and I had no reactions to it like I have had with other brands. It really suits me and I will continue with the whole range. Its worth the spend.

It’s okay
This is most definitely not worth the price. It is priced at the exact same price point as their original detox shampoo which is the far superior shampoo that k18 make. This one wouldn’t be my choice of shampoo for daily use - it is literally just a plain shampoo with no apparent added benefits. It’s not bad, but I won’t purchase again.
