Shockingly little product

I love K18 and the dry shampoo changed my life but I would pass at least on the mini version of this. It’s shocking how little comes in this, I used it four times. It made my hair soft but I’m not happy about the price and the amount.

A must for bleached hair

My hairdressers recommended this to me after having my hair bleached. I always use in for a week after having hair bleached and then about once a month for maintenance. Couldn’t be without it!
