Best for Dry/Damaged Hair
I have been using this product for my very dry hair for the last week or so.The price is great for what you get! When I wake up in the morning my hair is so soft and I can feel the overall difference of the health of my hair.

Game-Changer for Damaged Hair!
I’ve tried so many products for my dry, color-treated hair, and K18 is one of the few that actually delivers noticeable results. After just a few uses, my hair felt softer, smoother, and much stronger. The shampoo cleanses without stripping, and the conditioner leaves my hair feeling hydrated but not weighed down. My hair also has more shine and less breakage, which is a huge win. Definitely pricey, but a little goes a long way — and the results make it worth every penny. Highly recommend for anyone dealing with damage or just wanting healthier hair!

Great product worth the money, saves color treated hair.
Great product does not bleach out hair that is colored. I don’t know if this is the pH balance or what but I have psoriasis and it seems to help with that as well versus other shampoos that actually irritate my scalp.

Life changing
K18 products saved my curls !! Is a little bit expensive considering the portion of the product but is definitely worth the buy. My curls had heat and hair dye damage and it look frail and loose, it took one try for my curls to pop back. The shampoo and the mask is definitely a staple on my curly hair routine.

Not sure it’s worth the hype?
I guess? Nice shampoo but wasn’t life changing. It washed my hair and had a nice scent— not too perfumed. I don’t want to knock it but I think it’s just fine. Hair is soft and moisturized.

Great for curls
I started using K18 Damage Shield Protective Shampoo after noticing my hair felt like straw every morning, frizzy, tangled, and lifeless. Especially post-swim workouts. Almost immediately, I realized it helped reduce frizz and snarls, making my hair much smoother and easier to brush without ripping it out. Now, my curls feel healthier and more resilient, and my weekly routine actually leaves me feeling confident instead of stressed, seriously, it’s been a game-changer!

WARNING May cause hair to dry out and snap off!!!
Used the K18 shampoo and conditioner as directed. Applied the K18 oil of three drops as directed . Air dried my long blonde hair and ends to about mid shaft almost immediately turned dry and crunchy! Used a large tooth wet comb and my hair snapped off! A lot of hair! Found out from a chemist that it caused too much protein to be forced into hair shaft which caused breakage.The breakage would have continued for two plus days!! I was instructed to wash K18 out with an argan oil shampoo ASAP to stop the reaction! If trying this just be aware this may happen to you and there is no warning label some hair types my experience this adverse reaction.

A riprova di come sia un prodotto estremamente personale lo shampoo, devo però dire che sono rimasta delusa che questo prodotto non abbia avuto nessun effetto su di me…anzi! Capelli vetrificati, brutti al tatto, nonostante siano seguiti lo spray e la mousse con i giusti tempi di posa. Soldi buttati, e nel mio caso, meglio mille volte Olaplex! Non lo acquisterò più.

It’s a nice shampoo great smell and lathers well. I can’t say yet it has reported damage in my hair but it’s a quality brand.

Helped improve my scalp and reduce dandruff. Only need a small amount for short hair so it lasts surprisingly long.Not the biggest fan of the bottle design as the lid can fill with water but that’s my only criticism.
