Is there a measurable metabolic cost to replacing one hair?
I’m curious whether there’s any scientific estimate of the metabolic energy required for the body to replace a single hair after it’s been plucked.
I realize hair growth is part of ongoing biological processes (cell division in the follicle, keratin synthesis, etc.), so this might not be something that’s directly measured. But has anyone attempted to estimate the energy cost on a per-hair basis, even as a rough calculation?
