    The review explores the multifaceted aspects of hair and scalp aging, emphasizing the biological processes behind hair pigmentation and growth, and the variations in gender and ethnicity. It highlights changes in hair fiber properties such as diameter, ellipticity, and elasticity that contribute to the characteristics of aged hair. The importance of scalp skin health in promoting healthy hair growth is discussed, focusing on age-related changes to the scalp skin and its microbiome. The review concludes that while chronological aging and environmental stresses impact hair health, proper scalp skin care can significantly influence the appearance of aged hair, prompting the development of cosmetic solutions to delay or improve these effects. Additionally, it highlights the complexity of hair aging and the potential for reversing greying and hair loss under certain conditions, with treatments targeting growth factors to stimulate hair growth. The document underscores the complex interplay between hair and scalp aging, with variations across genders and ethnicities, and suggests that maintaining scalp health can mitigate some aging effects on hair.
