alterations in hair color due to melanin variations
Pigmentary changes refer to alterations in the color of the skin, hair, or eyes due to variations in the production or distribution of melanin, the pigment responsible for coloration. These changes can result from various factors, including genetic conditions, hormonal imbalances, sun exposure, aging, or certain medical treatments, and can manifest as hyperpigmentation (darkening) or hypopigmentation (lightening).
