alteration in natural hair color due to various factors
Hair discoloration, also known as hair color change or hair pigment change, refers to the alteration in the natural color of hair. This can occur due to various factors such as aging, genetic predisposition, environmental exposure (e.g., sun, chlorine), chemical treatments (e.g., dyeing, bleaching), or medical conditions (e.g., vitiligo, nutritional deficiencies). The change is typically due to variations in the levels or distribution of melanin, the pigment responsible for hair color.
