New cancer drugs turn patients' gray hair BROWN in bizarre side effect that has left scientists baffled
Cancer patients' gray hair unexpectedly turned dark while taking new immunotherapy drugs, a new study reveals.
While chemotherapy is notorious for making hair fall out, the 14 patients involved in this report, some in their 70s, were all being treated with a new form of drugs called immunotherapy, which work differently and have different side effects.
In patients with lung cancer, Spanish researchers found the drugs had a knack for turning gray hair brown.
With the first patient, 'we thought it could be an isolated case,' said Dr. Noelia Rivera, a dermatologist at Autonomous University of Barcelona.
