Terrible

Worst product ever. Literally does nothing and it’s so expensive.

Need a hair perfume of this scent

This just smells so good. Yes it works but the scent is the main reason I use it over my other products I can’t lie. I need a hair/body mist of this scent asap. Performance wise it works well and is weightless on my very fine/thin hair though and I think has helped with my damage
