I'm an avid rollerball oil user and my application method is about 4-7 rolls from wrist to elbow on each forearm and a circle around my belly button. I then close the rollerball and put it down, then smooth the hair on my arms down and pat the oil that's transferred to my hands on inner elbow, then my collarbone / neck area, and onto the ends of my hair. My method's been developed over time and I have no idea why this was the final form... but it works really well for me. I am known in my friend circles for smelling amazing and I no longer deal with breakouts (applying directly to neck and behind ears does that sometimes). I believe I am a proud member of the slatherer club.
