I was mildly skeptical with this purchase because it’s such a large size with a low price. I’ve tried K18 before and it’s an absolute must for my hair, however, it’s ridiculously expensive. You will not find a better price for this anywhere else, trust me, I’ve looked. Thank you Sams Club for offering this. Please don’t stop!

The miracle solution. My hair was breaking off at an alarming rate. My colorist said use this. Well what a difference. I’ve very fine hair and have never been able to use leave in anything. However, I made an exception with this. And what a difference. My hair isn’t breaking and it isn’t weighted down. It’s shiny and full.

I recently tried the K18 hair treatment, and I must say, it exceeded my expectations. As someone with bleached hair, finding a product that effectively repairs and restores damage can be a challenge. However, K18 proved to be a game-changer for me.

The “professional” product is the same as the original. The price here gets you three times as much! Made my hair soft, shiny and more manageable. Better than Olaplex!

I will only buy k18 products through Sam's Club - you can't beat the price. I use this stuff religiously and recommend it to everyone I know - and I tell them to buy it from Sams!

Love, love this product. Works great on my naturally fine, very wavy hair. My hair would be very fuzzy when air drying. This product is just amazing. Just a dime size amount and the results are unbelievable.

This is an amazing product at a great price. A little squirt goes a long way and it even works in Florida's heat and humidity.

Appears to be the real thing! I compared my original k18 I bought from Sephora with this one and it feels to be the same 😁 such a great price

I noticed that my damaged hair it’s getting stronger and healthier, no more rubber feeling, awesome product

Excellent product. I have used K18 for 5 consecutive shampoos so far. I have long (past my shoulders), wavy, heavily highlighted hair. My hair feels more managable, less frizzy and healthy :) I highly recommend.
