Study Overview
Brief Summary
Androgenetic alopecia is a chronic pathology affecting approximately 50% of men at 50 years old and is characterized by a progressive miniaturization of the hair follicle leading to a localized baldness.
Although it has been shown that testosterone metabolism plays a central role in this pathology, targeting this biological pathway is not fully efficient to treat androgenetic alopecia, suggesting that other factors are involved, notably factors linked to the perifollicular environment. Moreover, the very specific pattern of androgenetic alopecia is not yet fully understood: the occipital and lower temporal areas of the scalp are always preserved. Once the hair follicle has disappeared, it is not possible to make it grow back, it is then important to provide a treatment that slows down the progression of androgenetic alopecia at the earliest stage of the pathology, and that specifically targets the affected area.
The aim of this study is to better understand androgenetic alopecia pathophysiology by a multi-omic approaches and biometrological analysis, in the same study, on the local ecosystem of bald scalp areas and non-bald scalp areas of adult with androgenetic alopecia, compared to scalp of adult without androgenetic alopecia.
