Patchouli have to like otherwise you probably rotate through when you're in for hours on the head. I love it and for me it could actually hold it a little longer.
Still you have to watch a little bit with the dosage. My first order went Rinse something in my pants because I'm a little too enthusiastically dealt with the oil ^^
As I said, I love patchouli. But the day after Gothic to smell, from the age I'm out;)
If you like patchouli, which can be accessed here safely.
But be careful with the dosage;)
