The Hype is Real

The hype is real. I’m switching to this product for my dry shampoo.

Use with caution if you are having a bad day

I wanted to love this but I’m actually so annoyed. It does the job of breaking up grease but oh my word does it make a bad hair to go from bad to worse. I take care of my hair and this made me want to scream. It made my hair feels so brittle and break. I have super wavy fine hair and I had so many knots at the end of the day I actually had to cut some out. If I were someone who littered, which I’m not, I’d throw this straight into the East River!!!! Thanks K18 for my latest haircut! This one’s on you 💖
