The pigment in nail polish directly interferes with measurement of
oxygen saturation of hemoglobin; that's why all fingernail and
toenail polish must be removed before surgery. If someone on the
forum has a pulse oximeter, an interesting experiment would be to
measure the pulse ox before and after hennaeing a fingernail. These
experiments were done with nail polish on volunteers (doctors and
nurses) and that's how those conclusions were drawn. Anyone
interested could try the journals "Anaesthesia" and "British Journal
of Anaesthesia" from 1991 to look up the exact reference for the nail
polish experiments. If someone could do these with henna, the
experiment would surely be publishable in a leading medical journal
since nothing has been published on this before.
