Summary of Customer Ratings & Reviews

Excellent after first use

K18 Hair Treatment has honestly been a game-changer for my hair. After just a few uses, I could already see a difference. My hair feels smoother, softer, and way less frizzy. I’ve struggled with heat and color damage for a while, and this treatment really seems to repair it from the inside out. It’s so easy to use—just apply it to damp hair, leave it in, and let it work its magic. The texture of my hair has improved too. It feels stronger, and I’ve noticed less breakage. The best part? It doesn’t weigh my hair down or leave it greasy, which is a huge win since I have fine hair. The shine is natural, and my hair looks healthier overall. That said, I would say the product might be a bit too heavy for people with really fine or oily hair, so it’s important to use just a little. Also, if your hair is extremely damaged, the results might not be as dramatic right away, but I think with consistent use, the difference would be even more noticeable. All in all, K18 is definitely worth the hype. It’s like a salon treatment in the comfort of your own home, and my hair has never looked or felt better. Highly recommend!

Saved my hair

Bought this and the hair mask when I thought bleaching half my hair while sick at home was a good idea and half my hair snapped off. It worked wonders! Can’t suggest it enough, it healed my hair and saved me from a mental breakdown. Now I use it when my hair is looking a little dull needs a pick me up. It has magical healing powers! It’s expensive but worth it when it works this well!

When it states detox it strips!

My poor hair after using this! I thought I would buy this for when I have been out and have hairspray or products in my hair. Gosh, it seemed to make my hair super dry it was so stripping. Perhaps this is only good for very oily hair that really needs a good wash. I have normal hair and it’s a no from me. Really regret buying it

the best detox shampoo

this is the best detox shampoo i have tried so far, although i only use it once a month so i do not strip my scalp too much it provides me with longer freshness and a greater clarity to my hair. It is great at removing product build up and cleanses the hair thoroughly.

Super shampoing

Shampoing très agréable, un petit peu suffit, pas besoin d'en mettre une tonne et je sens que mes cheveux sont bien "détoxifiés" après l'avoir utilisé ! L'odeur est agréable et il reste très doux pour le cuir chevelu (le mien est extrèmement sensible).
