Sometimes if there is no product around to help you with a problem, the answer may be in your fridge (or on your fries lol)

If chlorine from swimming pools is turning your blonde
tresses green or just giving your hair an unwanted scent,
eliminate the problem with a ketchup shampoo. To avoid a
mess, do it in the shower. Massage ketchup generously into
your hair and leave it for fifteen minutes, then wash it
out, using baby shampoo. The odor and color should be gone.
