Corrected entry: When Claire rescues the man in the fire, how come her hair doesn't burn up? While her body is able to regenerate, her hair wouldn't be able to, as it is dead tissue. If her hair was self healing she would never be able to get a hair cut.
Correction: Also, it could be that her hair simply didn't catch on fire. The man she rescued, his hair didn't burn up either.
Correction: Since it's not known just EXACTLY how Claire's power works it could be something like her body (including her hair) regenerates back to the point PRIOR to sustaining any damage.
