Lemon juice to lighten hair?

The myth is that you squeeze fresh lemon juice onto your hair, then sit in the sun for hours. In order to achieve any lightness, you would need to do it everyday for months, At the end you will just end up with very dry hair and very red skin. Trust me, I've tried it myself. Your best bet would be to buy some sun in hair lightener. It works the same, but it actually works :P
