Completely cover lemon slices in water in a small saucepan. Simmer
on low heat for 1 hour, adding more water as needed. Let cool, then
strain through cheesecloth.
Pour into a pump spray bottle.
(This is great for light colored hair, but since I don't have dark
hair, I don't know what effect it may have.)
Spritz as you would regular hairspray.
(Keep refrigerated)
