Neither. The last time I use hairspray on my hair was the 80's. Yes, I know, the 80's fashion is back, but there's no way I'm putting harmful chemicals on myself, even if I get paid $1K.
Harmful side effects
The chemicals used for fragrance and other additives in the product may cause various allergies
The propellants used for facilitating the hairspray to reach the nozzle and come out as a fine spray may be harmful
The FDA has banned the earlier propellants like CFCs (chloroflourocarbons) 11 and 12, because they were linked to ozone layer depletion
The propellants used today tend to be flammable
Earlier, certain lung infections like thesaurosis (when there is unwarranted storage of substances in the body) were believed to be caused by use of hairspray, though there have been no conclusive tests to prove this
Hairspray should be used as sparingly as possible in a room that is well aired, in order to prevent poisoning by inhalation
Sometimes constant use may cause the hairspray deposits to remain on hair for longer time that required – due to this you may have to wash your hair more often than usual
If you use too much hairspray and then attempt to set your hair it gets damaged
If hairspray is not washed away properly then it leads to inordinate dryness and brittleness of your hair
The risk of split ends and broken hair is higher with frequent use of hairspray
