Good leave-in

This leave in hair conditioner has become a staple in my hair care regimen as I’ve noticed my hair has become stronger and reduced shedding. Also, it also reduces my blow dry time… not sure if it’s because I’m using the whole K 18 product line. Hope that helps

Love it

I have just started using this and even after 1 wash with it I found my hair feeling better I’ve watch a lot of videos online saying to mix it in your hands till it turns white which is what I have been doing and found it work better that way
