Disappointed
I have used this product twice and unfortunately it has just made my hair drier than before and the following day the hair gets worse. I am following all the instructions on the bottle but its cleary not working for me.. I had high expectations from this product but it has disappointed me.
Duration of Use: A week

3rd bottle! It’s that good
This is my third bottle of k18 and I still love it. I notice such a difference in my hair straight away
