Perfect post-blowout oil to lock in smoothness and
I absolutely love this hair oil! I always use it right after blow-drying my hair as a finishing touch. It works amazingly well to maintain the smoothness of my ends and ensures that there is absolutely no frizz left behind. It leaves my hair looking super sleek, shiny, and feeling incredibly soft without weighing it down. It’s definitely a premium product that is worth every penny for blowout maintenance!

Didn’t live up to the hype !
I was disappointed with this product. It really didn’t do much. Ok tame frizzy hair as a temporary measure but no better than products which are significantly cheaper on the market
