Best EVER

Best shampoo ever! I didn’t think a shampoo would compliment the leave in treatment, but this shampoo is THE ONE

Not what I was hoping for

Makes my hair feel like straw while wet and hard to brush/comb out. Not sure what to think with all the other great reviews. By next day my hair looks like it needs washing again.will not order again.

Not authentic K18

Per Google Sam's Club is not an authorized reseller of K18! Turns out as well this shampoo is supposed to be black and it comes out white, I had bought a bottle from Sephora and they are an authorized reseller and the product comes out black which caused me to look into this. Just a heads up to everyone!
