Redheaded women emit a particularly distinct aroma

It has been scientifically proven that when redheads wear perfume, it will smell better than when worn by other hair types.

“Dr. Augustin Galopin first recorded this fact in his 1886 book “Le Parfum de la Femme.” He reportedly detected that redheaded women emit a particularly distinct aroma — that of ambergris, an earthy and sensual scent.”

Concerning myself, a guy with red hair,  I have unusually sensitive senses. I cannot wear strong colognes and use commercial soaps because I will get a headache. Its funny walking about and having the ability to smell what other people are wearing and what detergent they used. Actually it can be overwhelming sometimes. Sometimes I can catch whiff of a person downwind at over a block away.
