Need Advice: Canceling out Orange/Red Tones

 I have  a long hair history. I just have one question. I put an light ash brown with 20 vol. delveloper on my hair to cancel out the existing brassy orange tones. It did help alot, however, it is still too orange. In fact, I would like to completely get rid of them to have a neutral brown. Can I recolor with the same ashy light brown, to then cancel out more orange? Or do I need to do something different? thanks
