P3  MULTIFACTORIAL CLASSIFICATION OF MALE AND FEMALE ANDROGENETIC  ALOPECIA

Bouhanna P. Center Sabouraud - Hospital St Louis, Paris, France.

Various classification of male and female androgenetic alopecia proposed so far, deal with topographic evolutive patterns alone. In fact, classification of common baldness require rather a more objective, accurate and detailed approach of various modifications determined by the evolutive process.

We propose a dynamic multifactorial classification of certain parameters such as fixed distances of face, scalp laxitity and thickness and hair coverage. This includes density, caliber, shape, length, growth rate and hair color.

This multifactorial classification proved to be efficient during the fluctuations of different parameters after the use of molecules for hair conservation to define indications of hair restoration surgery and stage of maximal baldness. This approach will lead to a better evaluation of androgenetic alopecia evolution in both sexes, either spontaneously or under treatment.
