Is it safe to wash my hair 20 days after craniotomy?
Whether a patient can wash their hair 20 days after craniotomy needs to be determined according to the actual situation. If the wound has recovered well, washing the hair is generally permissible; however, if wound recovery is poor, washing the hair should be avoided. Detailed explanations are as follows:

If the surgical wound has fully healed within 20 days post-craniotomy, with no signs of infection such as redness, swelling, discharge, or pain, and the physician has permitted gentle cleansing of the head, washing the hair is acceptable.
If the patient's general health is poor, recovery is slow, or the surgical wound is large or deep, requiring a longer healing time, washing the hair should be avoided. If the wound has not fully healed or if complications such as redness, swelling, or skin breakdown are present 20 days post-surgery, washing the hair should be postponed to prevent worsening of infection.
When washing the hair, avoid vigorously rubbing the surgical area, water temperature should not be too hot, and irritating hair care products should be avoided. Additionally, adequate rest and sufficient sleep are important after surgery. Excessive fatigue and strenuous exercise should be avoided to promote recovery.
