Chop one lemon (or an orange for dry hair). Place in a pot with 2 cups water. Boil until half of the initial amount remains. Cool, strain, and place in a spray bottle. Store in the refrigerator. If it is too sticky, add more water. Add one ounce rubbing alcohol as a preservative and then the spray can be stored for up to two weeks unrefrigerated.
Heat 1/2 cup water to boiling or almost boiling, turn off the heat, and add 2 tsp. sugar and stir, add a couple of drops of rosemary oil and lavender oil to it as well, just for a little scent.  When it’s cool, pour it in a little spray bottle.
