Is it permissible to use a wig to treat the effects of surgical operations that caused wounds and scars on the head, and is there a solution for performing ablution (wudu') and ritual bathing (ghusl) without aggravating the condition?

We advise against wearing a wig, to avoid scholarly disagreement and out of piety. Wiping over it for purification is not sufficient. However, if it is necessary to cover wounds, inflammations, and the like, one may place bandages over them and wipe over the bandages during ghusl and wudu', provided that the covering is limited to what is necessary. If the wounds are exposed and water is harmful to them, there are several levels:

1. Exposed and washing does not harm them: They must be washed. 2. Exposed and washing harms them but wiping does not: Wiping is obligatory. 3. Exposed and both washing and wiping harm them: Perform tayammum. 4. Covered with a bandage or similar: Wipe over the covering, and it suffices for washing.

If wiping harms the covered wound, perform tayammum for it. Most scholars do not require wiping over the entire head in wudu', and wiping over part of it suffices, though it is more cautious to wipe over the entire head.
