I am new to this so bare with me.
Iwould like to find out what combination of hydrogen peroxide and shampoo or something else I could use to lighten my daughters hair. Any suggestions?
Thanks.

If your daughter has dark hair and you want to lighten it, I recommend that you take her to the salon. Dark hair has a lot of red pigment in it, and if you attempt use a hydrogen peroxide mixture on your daughter's hair, it will results in an unpleasant brassy color.
