LE Scent Equivalent to Cologne

I already loved the original mask so decided to pick this one up for the LE scent. The scent is not overpowering and is very comparable to men’s cologne. If you’re not a fan of scents, especially musky ones, I say stay away and go for the original. The mask itself is a 10/10 for keeping hair healthy, soft and manageable. It’s very pricey but worth every penny!

1000 stars! Non-incentivized

I haven’t cut my hair in a year trying to grow it long. Ends are damaged and I have to use masks and oils every time I shower otherwise it’s frizzy and fried. Even then by day 2 I’m struggling. I’ve used K18 twice and I can’t believe how healthy my hair looks. Not just the ends either the whole hair looks full of life and flowy. I have fine hair that is colour treated
