Hi,
Unfortunately these things happen ;0)
Unfortunately stripping permanent color from your hair is not something to be taken lightly. There are strippers you can purchase but I STRONGLY recommend you do not use them as they commonly cause damage to your hair in the form of striped proteins, dry out, and even hair loss.
My recommendation would be to go to a salon. They have products that can safely strip the hair or lighten it without causing the trauma you do not want. Hair stripping can be quite damaging if not done right for this reason the strippers are not routinely sold in normal stores. If you decide to go this route you would have to go to a hair salon store to purchase the stripper.
