Any foreign substance can be dangerous when inhaled in large amounts. Our body have defence mechanisms to help protect the lungs against that kind of debris. The little hair in our noses is there to filter the air we breath in (we should breath in our noses all the time). The snot in the nose and mucus in the lungs is there to catch the debris that gets past the nose hair. Much like fly paper. Then we cough it up or sneeze it out.
inhaling it inside a airtight plastic bag spraying it alot inside the bag
Its bad inhaling or not inhaling because its still going to get in your lungs.
No
Yes! I wouldn't go inhaling it straight from the can :-) but using it on your hair will be fine! I've had 2 perfectly healthy kids & hairspray didnt affect them.
Carcinogens
yes
yes, because your hair will look like crap. It's not "bad" to use hairspray on wet hair, it just won't work as well. Hairspray is meant to be used on dry hair.
yes inhaling too much can be poisonous and is very fatal and can make you sick.
no, it's bad for the enrironment.
Make sure that the hairspray doesn't contain any very bad ingredients for your hair.
Hairspray doesnt exactly damage it it makes it flamable and very dirty and greasy so make sure after using hairspray to wash your hair and also hairspray damages the ozone layer so if you are "green" that's not for you(:
yes it is bad for your health
