Science reveals/ Can gray hair turn color?

Hair turns gray when the cells that produce pigment, called melanin, stop functioning. This is usually related to aging, but also to factors such as stress, DNA damage, and biological processes in the body.

Recent studies show that in some cases gray hair can regain its color, but this mainly happens when graying is early or in cases where it is related to stress or temporary factors.

For example, it has been observed that when stress is reduced, some hair strands may regain pigment. This process is not permanent and does not occur in all people.

In most cases, especially with age, the process is irreversible, because the cells that provide color disappear. There is currently no proven treatment that completely restores hair to its natural color.

New studies are focusing on hair stem cells and ways to "reactivate" them.

There is hope that biological treatments for restoring pigment may be developed in the future, but there is no practical solution yet. /CNA
