A phenomenon discovered by chance
It was during a very serious study on a cancer drug, imatinib mesylate or Glivec ® , Novartis from the laboratory, the team of Dr. Mahon has been a gradual refilling of gray hair in 9 treated patients. Between December 1999 and June 2001, 133 patients with a particular type of leukemia (chronic myelogenous leukemia) were treated with Glivec ®. The drug works by inhibiting the action of an enzyme, tyrosine kinase. Among these patients, ten of them (five men and five women) had gray hair before treatment (mean age 63 years). Of these ten people, eight had their hair recolor, one has noticed this phenomenon on the hair.
Repigmentation occurred on average after five months of treatment.Mechanisms that could explain the action of such a drug on the hair and hair remain totally mysterious, but can become a real focus. It remains to wait for other physicians to report, too, side effects similar in their patients treatedés par cet anti-cancéreux.
