I dyed my hair light ash blonde but it now has a tinge of blue!! Help what do I do to get it right? My natural colour is mousey brown so either I want to go back to that or be a light blonde xx

What colour is your shampoo?

I've heard ash blonde has a tendency to do that- sorry. You can use natural lighteners if you want to make your hair lighter or dye it a light blonde, it may get rid of the hue

Orange counteracts blue. Hence, you can briefly apply a semi permanent color with a warm coppery tone to offset the blue. Do not process too long or you will have unwanted warm tones.
