Fine, breakage prone hair approved!!

I have tried so many different products that claim to repair damage over the years and have never really been wowed by them. I’ve been using K18 for about 3 months now and it’s made a huge difference in the amount of split ends I get and length retention. I have fine thin hair that is easily weighed down, but using 2-3 pumps of this leaves my hair so soft and non-greasy. I don’t have bleach damage anymore, because i’ve grown my natural color out. However even my natural fine hair breaks sooo easily and this has helped it preserve length. I still get some breakage but I think that’s just the nature of having fragile hair strands. i think it’s worth the price and i have never been someone who would pay such a high price for hair care!!

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!
