Scientists have found the key to preventing graying of hair New research may be one step closer to solving the question of how to prevent graying of hair.

Whether you embrace your gray hair or prefer to mask it, new research draws on the science behind the visible signs of aging.

" However, as your hair ages, falls out, and regrows repeatedly, more and more stem cells get stuck in a compartment called the hair follicle bulge,” family doctor Tatiana Zakharova says for MedicForum..

These hairs cannot return to their original location where proteins can help them regenerate into pigment cells.. Unfortunately, in this position, your hair loses its normal color, resulting in a silver tint..

A new study looked at physically aged hair in mice, focusing on animal skin cells also found in humans called melanocyte stem cells, or MsCs..

Your hair color is determined by whether the non-functional but constantly replicating pools of McSCs within the hair follicles receive the signal they need to produce the protein pigments responsible for giving hair its color..

"

The problem occurs when they stop moving and get stuck in a stem cell compartment called the hair follicle bulge.. Once stuck, McSCs remain in the bulge and do not retain their color.

The researchers explained that McSC adaptability is absent in other self-regenerating stem cells, such as those that make up the hair follicle itself, which are known to only move in one direction over a set timeline as they mature..
