"It makes my hair so soft and weightless, I absolutely love it. Most of the product leave my hair greasy and I can’t even style it, and right after washing I have to put it in the bun. It’s a nightmare! But not with k-18. Makes my hair feel so luxurious, it’s like I just left the salon. Can’t recommend this product more!"
