Do not buy.
I bought this with the matching shampoo. I feel like ive had a little more fallout than usual, and it really, really, dried my hair out. The conditioner is really thin, like V05 conditioner thin. The bottles seem cheaply made. Will not be purchasing again.

Not the same
K18 re-formulated this conditioner and it’s not the same. Much thinner and therefore less hydrating :/ the packaging has been downgraded too. Feels like a cheaper product all around. Will be trying something new next time!
