In the name of Allah the most Gracious the most Merciful
The answer to your question is as follows:
It is obligatory to do the masah (wipe) of your head during ablution (wuzu), because it is an essential part of wuzu, so it will be necessary to wipe it in any possible way. And if there is a bandage on the entire head, you should wipe over the bandage and it will be sufficient. And Place your hand over your forehead and recite 'Ya qawiyyu' eleven times after each prayer. Keep your heart and mind calm and focus on the remembrance of Allah, no need to indulge so much in worldly affairs. Pay full attention to your prayers, recitation of the Holy Quran and seeking forgiveness. May Allah bless you and grant you recovery!
And Allah knows best
