    Glossary Hair Follicle Aging

    gradual decline in hair follicle function and structure over time

    Hair Follicle Aging refers to the gradual decline in the function and structure of hair follicles over time. This process can lead to thinner, weaker hair, slower growth rates, and eventually hair loss. Factors contributing to hair follicle aging include genetic predisposition, hormonal changes, oxidative stress, and reduced cellular regeneration.
