There have always been discussions, and debates on hairspray production, as the chemicals used are prone to harm consumers and the environment to great lengths. With strict health and environmental protection guidelines strengthening over the years, it is safe to say most hairsprays contain less harmful content these days. There are even organic hairsprays buzzing in the market.

What Happens if You Put Hairspray on a Spider?

Since spiders are thin-skinned organisms, they use diffusion as the mode of respiration, which means they breathe in and out through their skin. Hairsprays contain harmful chemicals such as polyvinyl acetate and polyvinyl pyrrolidone, denatured alcohol, and HFC (hydro-fluoro carbons), which are toxic.

These chemicals are put together to harden when sprayed onto the hair swiftly. When this hairspray is sprayed onto spiders, they cover their skin and immediately set, cutting out the connection between oxygen and their respiratory organ. It will suffocate them, starve them, intoxicate them, and cause paralysis, immense irritation, inflammation, and pain, eventually slaughtering them.

Even if the hairspray ingredients are not strong enough to kill the spiders, they will still end up brutally and critically harming the spider. And the fact that spiders are sentient beings (can have feelings) makes it worse.
