Hair advice

so 2 weeks ago i dyed my hair for the first time ever and just on tuesday i realized certain sections are brown so i have to retouch. the problem is i’m super stressed because today is my birthday and i didn’t expect for some parts to fade so now i have to retouch it but i have plans today and tomorrow i have a baseball game tomorrow so since im retouching it today i know i can’t wash it tomorrow and im super upset cause i have really really oily hair so by tomorrow my hair gonna look so oily😭 and i really wanna wash it and look cute but they told me i have to wait 24-72 hours. dry shampoo doesn’t work for me my hair gets flakey and more oily. do y’all have ant recommendations or advice that i could do or tricks?
