Can hairspray stop your hair from growing?

Hairspray has alcohol in it. It drys out your ends.

However, your hair starts from follicles inside of your head. Your hair is actually dead. So, while hairspray can damage your hair, it will not stop your hair from growing! Just wash your hair. If you have a lot of build up, mix baking soda with your shampoo and wash your hair! Just occasionally though!
