going to a salon and having it done
Use spray bottle of 1/2 peroxide, 1/2 water every day or when ever you wash it, this will gradually give you lighter hair and high lites.
you could try this stuff called sun-in...u spray it on and can lay out in the sun or blow dry the highlights in. it works great for me. :)
