The problem with scented products is not so much the smell itself as the chemicals that produce the smell. Nearly all scented products currently on the market are made largely or entirely of synthetic chemicals, usually derived from petroleum or coal tar. Nearly one-third of the chemical additives used in perfumes and other scented products are known to be toxic, and it's not safe to assume that the other chemicals are safe just because they aren't yet known to be toxic. And just one perfume can contain more than 500 chemicals.
Expensive products are just as likely as cheap ones to contain synthetic chemicals.
The only safe assumption about scented products is that they contain numerous toxic chemicals which constantly vaporize into the air and attach themselves to the hair, clothing, and surroundings of anyone who wears them. These chemicals are skin irritants, suffocants, eye and respiratory tract irritants, and neurotoxins. And that's why wearing scented products isn't just a personal choice. The chemicals don't care. Prevent its contact with skin or eyes because it is an irritant and sensitizer.
