Can we make grey hair dark again?
Global Repigmentation Strategy of Grey Hair Follicles by Targeting Oxidative Stress and Stem Cells Protection
Not medical advice. For informational purposes only. Always consult a healthcare professional. Terms
Scientists found that too much 'rust' in hair roots (called oxidative stress) causes hair to go grey by hurting the color-making cells. They made a special ingredient that helps protect these cells and turn the color back on. In a test with 44 men, their grey hair got darker after 4 months.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Using antioxidant-rich products on your skin or taking them as supplements might help turn some gray hairs back to their original color by protecting hair roots and helping pigment cells work better.
A study found that using a certain ingredient for 4 months helped reduce grey hair in men — it made fewer hairs turn grey and lowered the number of grey hairs per patch of scalp.
Too much oxidative stress might lead to fewer pigment-producing cells in hair and cause hair to lose color, based on lab studies that simulate this stress in human hair follicles.
A certain ingredient might help prevent hair from going grey by protecting the cells that give hair its color, at least in lab tests using real human scalp tissue.
