benefits of a cosmetic anti-hair loss in males with hair loss

Conditions: Androgenetic Alopecia

Summary: androgenetic alopecia (aga), also known as androgenic alopecia or male pattern baldness, is the most common type of progressive hair loss. aga is a polygenetic condition with varying severity, age of onset, and scalp location of hair loss. in men, hair loss typically involves the temporal and vertex region while sparing the occipital region: the characteristic "horseshoe" pattern. incidence and prevalence of aga depend on age and race. vichy has developed a new cosmetic anti hair loss lotion with the aim of acting on androgenic alopecia. the aim is to improve the efficacy on hair loss of the association of the lotion with finasteride versus finasteride alone. the primary objective of this investigator-blinded, randomized multi-center study is to quantitatively evaluate, using the phototrichogram method, the efficacy of a lotion associated with finasteride versus finasteride alone on hair growth parameters in male subjects with androgenetic alopecia.
