Quick Brainstorm; Green Tea Hair/Scalp SPray All Day?

Hey everyone!

Simple brainstorm here, can anyone see any problems with constantly spraying my hair/scalp (I have long hair so it can be hard to reach the scalp) with green tea? I just put two teabags of green tea (Celestial brand, unfortunately I have the antioxidant version, which is just normal but with 100% RDA of vitamin C, I'd prefer the regular version but I ran out) in maybe two cups or so of boiling water, cover the pot and let it sit for a few hours or until it cools, then I'm going to put it in a spray bottle and spray my scalp throughout the day whenever possible, just spray it, let it dry, spray it again, etc.

Any potential problems? Maybe too much caffeine getting absorbed making me jittery?

Thanks
