I spend a decent amount because I am a PJ.
I sort of go in spurts of trying new stuff and lately I've been interested in conditioners and haven't been styling my hair very much.
But I really could probably go for almost a year without buying anything except more of the Jessicurl GLS because my cabinets are overflowing! In fact, I should probably either throw away or sell/swap a bunch of things.
