So far I really like the combo. They mixed with an Aveda base called Chakra 6. However, just the three smelled great together. She did a a little heavier patchouli, then a little less lavender and the least amount of vanilla. I think I might be interested in playing with the amount of vanilla, as that is a scent I like and don't get headaches from.
Most people that get headaches from scents can tolerate a pure therapeutic food grade essential oils. I have a blend called m-graine it's used to help migraines . I don't like strong synthetic smells or overly strong smells. I have a sensitive nose. I hate the smell of ciggeretts I can smell someone that has smoked a mile away even if it was an hour ago. Pam
