Cancer therapy is known to cause patients’ hair to fall off, but a few new cancer drugs apparently have a completely different side effect – they restore pigment in older people’s gray hair.
Spanish researchers testing three new cancer drugs – Keytruda, Opdivo and Tecentriq – for negative side-effects in cancer patients made a very surprising discovery. After using the drugs, 14 of the 52 patients involved in the study saw their gray hair go brown or black again. The findings were recently reported in a paper published in the JAMA medical journal.
