I recently ran out of hairspray and thought that there just HAD to be some way to DIY hairspray. Lucky for me, there is! (and it runs on the el cheap side, so I was a fan. We're talking under 25 cents and only 5 minutes to make. Total win.
4 tsp sugar
1 cup water
1 tb vanilla
Heat water to boiling, add the sugar and vanilla. (in this case, the alcohol in the vanilla is used as a stabilizer and preservative, and the scent is a bonus! If you don't have real vanilla, DON'T use imitation, just use a 1 tb of vodka and a few drops of your favorite scented oil).
Put the mix in a spray bottle and you are good to go! DIY hairspray on the fly!
