The secret of white hairs

The
cells, called melanocytes, which produce capillary pigment, have been first grown in vitro at the British University of Bradford. Scientists have awakened unactive melanocytes extracted from the root of white hairs.

The bleaching of the hair can therefore have a opposite way, that is, a spontaneous blackening of the white hair. However, researchers claim that the lotion to activate hair melanocytes will not be ready in the old ones of the night.
