The value of microscopic features in the examination of human head hairs: Anslysis of comments contained in questionnaire returns

Comments received in response to a questionnaire seeking opinion about hair examination have been considered. The questionnaire was in two parts: the first was concerned with the description of microscopic features and the second with the use of numerical features and data sheets in hair examinations. The same format is used to present a synopsis of the many individual comments and suggestions contained in questionnaire returns. It is argued that a hair examination form can contribute to more effective hair examinations although not replacing direct side-by-side comparisons. A hair examination form is presented with recommendations for its use.
