Psychosocial stress levels are linked with hair greying and reversal

22-Jun-2021

Key points from article :

Graying process can be undone—at least temporarily.

Researchers provide the most robust evidence of this phenomenon.

Ralf Paus, study co-author says "...graying is probably much more reversible ...".

Martin Picard, mitochondrial psychobiologist says, "...Maybe the hairs that turn white first are more vulnerable or least resilient".

Researchers found 14 people, ranging from 9 to 65 years old with various ethnic backgrounds.

They developed a technique to digitize and quantify the subtle changes in color.

Which they dubbed hair pigmentation patterns, along each strand.

In 10 participants between age 9 and 39, some graying hairs regained color.

This occurred not just on the head but in other bodily regions as well.

In late 20s and early 30s when graying has just begun, is probably when the process is most reversible.

Association between hair graying and psychological stress also investigated.

Times when graying or reversal occurred corresponded to periods of significant stress or relaxation.
