i have two types of fixative, one for charcoal and one for my sennelier pastels, which cost $15 (but its made specifically for pastels and its worth it considering the pastels are 3.50 a stick)
i've never used hairspray but i caught my brother trying to last week and gave him my fixative. you know they make workable fixative so you can spray and keep working. And i don't think its $8, more like 5.49 or something i say just spend the money, its lasts a long time and good tools are the way to go.
dick blick art store is your friend. they are also cheaper online.

The evil, evil nap
It lures
you succumb
But only with good intent
Shortly I will rise
But you do not.
Do not succumb
