His hair needs cutting badly

Hi,
I assume that you mean that his hair is badly in need of a cut. In other words that his hair really needs to be cut now. In your sentence by putting ‘badly’ at the end of the sentence you suggest that someone should cut his hair badly/not well. What you meant to say was: His hair badly needs cutting/
