I'm a big hairspray user - have to have it to keep my bangs from misbehaving.

After spraying hairspray in my bangs  for several days, I notice that there are specks in my bangs. Even after shampooing them real well. Hairspray buildup is what it is. What I do to take care of the problem is cheap and easy-peasy. I keep a box of baking soda in the shower. When I still have shampoo in my hair, I use about a quarter-size amount of baking soda and rub it with my bangs between my hands and then rinse off as usual. No more hairspray specks!
