If you are referring to a credit card cash advance, it is generally credited to the account 2 days after repayment, and the available cash advance limit is restored. This is the bank's account entry process and does not affect personal card consumption. If you are referring to a cash lending business such as E-Zhao Loan, you can try to apply after repayment, and the specific results will be subject to review.
