Get your torches and pitchforks... I cannot stand Old Spice. There's some component of the fragrance that makes me nauseous and provokes a splitting headache. I've tried it many times during my shaving life, and in many formulations (Aftershave, cologne, deodorant) and all give the same effect. There are a few others that must have the same component and provoke varying degrees of the same reaction- Clubman, Brut, British Sterling, Stetson if I use too much- but OS remains the worst offender. As far as simply disagreeable scents, The Veg and many of the newer aquatics lead the pack without making me physically ill. The first time I took the plunge on The Veg, my long-suffering fiancé spent all day looking for where the cat had peed. I'll stick to my core rotation of AV, English Leather Pinaud Special Reserve (yeah, I like it), and Aramis.
