I am going throught the same exact thing right now trying to fade my red hair , well auburn red , back to my natural bleach blonde hair , & this is the natural non-damaging steps I have taken .Vitamin C tabelts & Dawn dishsoap & a really good shampoo
Mixed in a bowl & applied to wet hair .
I added a bit of reg. shampoo as well , Head & shoulders is best or a clarifying shampoo but it doesn't really matter I will be using mane n tail . What I am doing is washing my hair with dawn dishsoap for a few days
& then do that process

I have done two applications of this /7 my hair has lightened up tremendously . I am very happy with how its turning out . Good luck hope this helps , you can even add raw honey or baking soda to help it the active ingredeint is the vitamin C and Baking soda .
