Schwarzkopf Live Hair Colour

Hello, I dyed my hair purple Mystic yesterday and I heard that if you bleach your hair and go to the pool it goes green. Does my hair have the same effect? Schwarzkopf Live Colour XXL I Mystic Purple permenent

Cannot you wear a hat pool just to be on the safe side.

Hair dyes do not wash in the pool - the pool if they would be flooded with color.

my friend did and it does not work or change color, and it was not permanent.

read the packets, im not sure he should not do it, maybe its just a myth?
