Hair Extensions

Odds are this won't ever amount to anything, but I was reading a recent story that brought this question (which was NOT part of the plot there) to mind, and I figured there were people here who were likely to know a lot more about hair extensions than I do.

A man goes through emergency surgery and, after being comatose during both the operation and immediate recovery, awakens to find (either expectedly or otherwise) that he has become an attractive woman. Unless the medics have kept the patient asleep for weeks, that seems unlikely to include long hair.

Consider a situation where someone had a crush on the patient that they couldn't act upon until he became a woman. If that person saw fit to have hair extensions woven in before allowing her to awaken from the coma, would the patient realize reasonably soon that the hair wasn't her own, or could she go along for some time assuming that the operation that turned her female had also lengthened her hair?

Thanks, Eric
