lavander and jasmine are my 2 favorite combos for aroma
I stay away from neroli cause it inducess narcolepsy in ME one whiff and I'm out like a light.
peppermint and hemp oil soap wakes me up in the morning better that any coffie... I found out My friends fiancee( prob his new wife by the time you read this) and I both love
DR. Bronner's magic soap 18-in-1
not practical for client use but great stuff for personal use.
I love the other lists I read please post more, the olfactory sense is the one most tied to memory, even the slightest hint of patchlouli sends me into a fit of anger cause of someone who always smelled of it, did some very wrong things to people I love.
The smell of sandlewood always takes me straight to the arms of a loving ex-girlfriend.
All essencials will mean different things to different clients. The best thing I would think of is to compile a list from the previous posts, make a few combos and offer a choice, gauging there reaction as they smell.
What can be a calming scent to one person can bring back horrible feelings in anouther.
OH YEAH TEA TREE FOR STINKY FEET
