I use this mostly as a leave in conditioner overnight. My hair tends to get dry and tangled over the course of a day from working outside year round. Putting a small amount of the Premium Grooming Oil on takes my hair from dry to a healthy shine. Hair feels soft and smooth in the morning. Also works ridiculously well as a beard oil.
The addition of Squalane does take this up a notch from the other oils, but it's hard to say exactly why it feels better. It tames fly aways better for sure, and the hair feels softer than with other oils.
I got the Jazz Scent and its sooo good. Def does its job as a grooming oil as well. My hair is super soft and conditioned after using it. My hair is naturally on the dryer side.
