B1.1 Diffuse Hair Loss in Women; What to Do? Hugh Rushton London, UK & Gerhard Lutz Wesseling, Germany Part I: The Basics: What is diffuse hair loss? How do you define it? How do you treat it? In this seminar we will look at the basics: the three fundamental variables; hair density, hair diameter and per cent growing (anagen:telogen ratio) and how they can provide a specific definition for diffuse hair loss. We will try to obtain agreement on standardising parameters to define diffuse loss of hair without loss of follicular units from conditions that involve loss of follicular density or exhibit a delay in anagen initiation with or without increased hair shedding. Methods used to evaluate these hair variables will be covered, as will possible causes. What evidence based diagnostic and relevant serological investigations should be taken into consideration to solve this problem? What therapeutic options, specific to diffuse hair loss are available and what is the implication of poor hair care?Part II: How to deal with it: In the second part of the seminar the clinical investigations to evaluate diffuse hair loss (pull test, wash test with or without estimation of hair weight, phototrichogram, computer assisted phototrichogram and pluck trichogram) will be examined. Discussion of the hair growth cycle and the different hair root patterns and the characteristic features of anagen, catagen, telogen and dysplastic hair in relation to epilating procedures. A practical demonstration of the pluck technique and correct interpretation of freshly plucked hair roots under different conditions will be demonstrated. Relevance of the results for further therapeutic strategies and a discussion of the necessity for additional investigations and answering relevant questions from the audience will be an important aspect of the seminar. Audience participation will be actively encouraged. |
