P#52  Hair growth measurement in genetic hair disorders

Dominique Van Neste. Skinterface, Tournai, Belgium

We report data recorded with high resolutive contrast-enhanced phototrichogram (CE-PTG) method in a number of genetic hair conditions. Those include monilethrix, trichorhinophalangeal syndrome, alopecia triangularis of Sabouraud and Becker's naevus of the scalp. In all these conditions hair growth appears clinically modified but the exact disturbance remained largely un-documented. Our findings illustrate that AGA is not the only field of application of the CE-PTG. The clinical developement of androgenetic alopecia in male and in female patients are of course also genetically conditionned. Due to frequent occurrence of such conditions, AGA data are usually reported and analysed separately as statistical tables; we thought that an occasionally very severely affected young patient might become a case for diagnosis.
