What should a person do who shaved their head before performing 'Umrah or Hajj, then completed the Sa'i (ritual circumambulation between Safa and Marwa) but their hair had not yet grown back? Does the ruling for the sick or those with an ailment in their head apply to them? And what is the specified amount of the fidyah (expiation) mentioned in the verse: "And whoever among you is ill or has an ailment of the head, then a fidyah of fasting or charity or sacrifice"? What is the intended meaning of "sacrifice" (nusuk) in this context?

It is recommended for a person who has no hair during Hajj or Umrah (such as a bald person or someone who has already shaved their head) to pass the razor over their head. However, this is not obligatory, nor does it entail a fidyah (expiatory offering). If hair grows back after shaving, they are not liable for anything. The verse in Surah Al-Baqarah (196) does not relate to this issue; rather, it specifically pertains to the permissibility of shaving or shortening the hair for a sick person in exchange for a fidyah (fasting for three days, or feeding six needy persons, or sacrificing a sheep).
