Hi guys my natural hair colour is mousy blond I had it dip dyed but it went wrong so I had to dye it all a bleach blond I then died it brown and now I really want my natural blond back does any one have any ideas of how I can get it back to mousy blond with out it going a orange or yellowy green x

Wait for a little bit until your roots go in until you can get it professionally dyed? You've removed colour so you need to add it back, the problem is getting the colour right and touching it up as it fades.
