I like the scent of grapefruit oil. I read somewhere that people tend to estimate the age of a woman wearing grapefruit oil as about 6 years younger than her actual age. I thought this was silly then went out in grapefruit oil perfume and had two people comment, seperately, that they thought I was about 28, when I'm actually 34. Could be coincidence. Who knows? Love the scent though.
Ylang ylang is also nice. Sometimes I put it in my hair. Also patchouli and food scents like vanilla and chocolate oil.
