| Chemotherapy is known to make patients’ hair fall out, but the 14 people involved were all being treated with new immunotherapy drugs that work differently and have different side effects from chemotherapy. A Spanish study suggests those may include restoring hair pigment, at least in patients with lung cancer. | Chemotherapy is known to make patients’ hair fall out, but the 14 people involved were all being treated with new immunotherapy drugs that work differently and have different side effects from chemotherapy.

| Noelia Rivera, a dermatologist at Autonomous University of Barcelona, said they thought it could be an isolated case when it happened with the first patient.

| All but one of the 14 patients in the Spanish study responded better to treatment than other patients, suggesting that hair darkening might be an indication that the drugs are working, the researchers said. | All but one of the 14 patients in the Spanish study responded better to treatment than other patients, suggesting that hair darkening might be an indication that the drugs are working, the researchers said. |

| “It’s a fascinating report – one of those things that comes out of the blue,” said June Robinson, a Northwestern University research professor in dermatology.

| Rivera noted that the drugs used in the study had serious side effects that made them unsafe for healthy people. But if it is confirmed that they do change hair colour, a different drug could be developed to treat grey hair, she said. | Rivera noted that the drugs used in the study had serious side effects that made them unsafe for healthy people.

| The pharmaceutical industry has previously capitalised on unexpected drug side effects. Examples include the male pattern baldness drug Propecia, the eyelash growing drug Latisse, and Botox anti-wrinkle injections. Active ingredients in these drugs were initially approved to treat enlarged prostates, eye pressure problems, and eye muscle spasms. | The pharmaceutical industry has previously capitalised on unexpected drug side effects.
