Hypothesis: I read somewhere that if you spritz a bit of hairspray on your finger and brush it upwards into your bare eyelashes, you get a more natural-looking enhancement than with mascara.
I borrowed some of my sister’s hairspray (because I don’t believe in putting the stuff in my own hair) for this experiment. The brand was Suave, though I’m not sure what it was called specifically.
Conclusion: Before my fingers even came close to my eyelashes, the potent chemicals of the hairspray made my eyes water, which in turn made any effort to keep hairspray on my lashes impossible. Once I was finally able to stop the Niagara Falls coming out of my eyes, I got the stuff on and noticed not appreciable difference to my lashes. DROP this tip!
