Reversible causes exist
Stress, nutritional deficiencies, or illness-related grey hair might regain pigment if underlying issues are addressed, as some studies show partial pigment restoration after stress relief.

Collagen supports hair structure but does not influence melanin or reverse greying. Claims otherwise lack scientific proof.

Nutrients to support hair
Vitamin B12, copper, antioxidants, iron, and zinc may delay greying progression by supporting melanocyte health but can’t reverse grey hair.
