I suggest a familiar fragrance, generally either a heavy musk or something with notes of powder or bergamot. Those seem to work best. Most important is that it work with you. Ive been realizing lately that fragrance helps a lot with attachment rates. Light fragrances -can- work, but its a challenge. BTW, never use androstadienone on your hair. It seems to have staying power almost like androstenone. Sexual is a good starting point.
