Researchers are in hot pursuit of a "cure" for gray hair—and they're getting closer.
A study published last year showed that gray is caused by hydrogen peroxide and other cell-damaging molecules that build up as we age, bleaching color from the hair. The absence of an enzyme called catalase allows these molecules to accumulate, but EXT Life Sciences, a Michigan-based biotechnology company, believes it has found a chemical compound that can restore catalase and thus return hair to its original color.
The company is working to incorporate the ingredient into leave-in conditioners and serums, says cofounder Stanley Terlecky, PhD, professor of pharmacology at Wayne State University School of Medicine.
And across the Atlantic, L'Oréal's Paris-based hair biology research group recently identified a pair of genes that may determine the longevity of the cells that give hair its color. L'Oréal scientists are hard at work developing a treatment (either a pill or a topical formula) to block the progressive decline in these color-giving cells and stop—or at least slow—the graying process, says group director Bruno Bernard, PhD. Lets hope they make it!!!!
