Hairspray
Beauty, Your Health, and the Environment
Hairspray is by far the most dangerous beauty product to the ozone and the environment.  First, there are many VOC’s (volatile organic compounds) in hairspray, which cause harm to the ozone.  These compounds, such as methane, are famously known as CFC’s, or chlorine, fluorine, and carbon, and have been directly related to global warming.  When CFC’s are released through an aerosol hairspray can into the air, solar radiation high in the sky breaks the compound apart.  One chlorine atom has been known to break apart 100,000 ozone particles.  It is important that the ozone stay in tact because it protects the earth from harmful UV radiation, which is harmful to humans and also heats the earth, thus causing global warming.  Aerosol sprays pose these threats, while pump sprays are slightly safer.  However, scientists and doctors alike recommend staying away from hairspray whenever possible.  In lieu of buying dangerous hairspray, you can make your own hairspray with by placing a slice lemon into two cups of boiling water.  Next, cool this and leave it in the refrigerator.  After, add one ounce of rubbing alcohol.  You can use this for up to two weeks.  This homemade hairspray is safe and a good alternative to harsh chemicals.
The Environmental Dangers
When a person thinks of the health effects of hairspray, one most likely thinks of how hairspray causes a cough. While this is true, hairspray has a more drastic effect than a few coughs. Common chemicals found in hairspray are aerosol propellants, alcohol, carcinogenic polyvinylpyrrolidone plastic, formaldehyde, and artificial fragrance, which can cause low blood pressure, breathing difficulty, coma, as well as irritation of the skin, eyes and lungs. These chemicals also increase the risk of developing the lung disease thesaurosis over a period of time. Luckily, most are able to recover from this disease after discontinuing the use of hairspray. While the production of hairspray has improved and today no longer contain various toxic chemicals such as vinyl chloride and methylene chloride, still cause various health problems. Although it has not been proven that ingredients like propylene glycol have cancer-causing properties, it is still classified as a carcinogen. What is probably most harmful about hairspray is that many of the chemicals fall under ingredients as simply "fragrance," making it difficult to determine their safety.
