Symposium Proceedings of the 4th Intercontinental Meeting of Hair Research Societies: “The World of Hair 2004”

The 4 Intercontinental Meeting of Hair Research Societies organized by the 5 Hair Research Societies (NAHRS, SHSR, EHRS, AHWRS, KHRS) was held in Berlin, Germany from June 17 to 19, 2004. 514 participants from 40 different countries, worldwide, were able to experience the global unity of researchers and clinicians as well as representatives of cosmetic and pharmaceutical companies during this highly stimulating meeting, the largest gathering of hair research societies ever held. The high-level scientific program combined both a profound insight into current clinical diagnostic and therapeutic aspects, as well as the latest research findings. During the three days meeting, clinical courses, key note and plenary lectures, workshops and satellite symposium with up to 100 oral presentations and 160 poster presentations provided for the latest knowledge in the physiology, pathogenesis and therapy of hair and hair disorders (www.hair2004.com). This special issue of the Journal of Investigative Dermatology Proceedings serves as a record of the progress achieved up to now in the World of Hair.

Follicular Penetration and Targeting

In the past, intercellular penetration was assumed to be the most important penetration pathway of topically applied substances. First hints that follicular penetration needs to be taken into consideration were confirmed by recent investigations, presented during the workshop "Follicular Penetration and Targeting" at the 4th Intercontinental Meeting of Hair Research Societies", in Berlin 2004. Hair follicles represent an efficient reservoir for the penetration of topically applied substances with subsequent targeting of distinct cell populations, e.g., nestin-expressing follicular bulge cells. The volume of this reservoir can be determined by differential stripping technology. The follicular penetration processes are significantly influenced by the state of the follicular infundibulum; recent experimental investigations could demonstrate that it is essential to distinguish between open and closed hair follicles. Topically applied substances can only penetrate into open hair follicle. Knowledge of follicular penetration is of high clinical relevance for functional targeting of distinct follicular regions. Human hair follicles show a hair-cycle-dependent variation of the dense neuronal and vascular network. Moreover, during hair follicle cycling with initiation of anagen, newly formed vessels occur. Thus, the potential of nestin-expressing hair follicle stem cells to form neurons and blood vessels was investigated.

Hair Pigmentation: A Research Update

Hair is a uniquely mammalian trait with important functions, most easily appreciated in furred mammals. Our skin and hair color contribute very significantly to our overall visual appearance by highlighting striking variations between human sub-groups. Although melanins, hemoglobins, and carotenoids define the color perceived at the skin surface, our hair color relies only on the presence or absence of different melanins. The hair shaft's physical aspects provide only minor color modification. Various selective evolutionary pressures have determined that within the context of our specific ethnic backgrounds a bewildering array of natural shades are seen; ranging from yellows, reds, and browns to black and that harbinger of lost youth, gray/white hair. Skin/hair follicle melanins are formed in cytoplasmic organelles called melano-somes produced by neural crest-derived pigment cells called melano-cytes and are the product of a complex, phylogenetically ancient, biochemical pathway called melanogenesis. The following provides a review of research presented at the 4th Intercontinental Meeting of Hair Research Societies 2004 and so is not intended to represent a fully comprehensive overview of the subject-for that readers are directed to key references.

Introduction to the Symposium Proceedings of the Third Intercontinental Meeting of Hair Research Societies

It gives me great pleasure to announce that the Third Intercontinental Meeting of Hair Research Societies, held from the 13th to the 15th of June, 2001 at Chinzanso in Tokyo, was a resounding success, with over 320 participants from 20 different countries including America, Europe, Australasia and Asia attending. On behalf of the Society for Hair Science Research (SHSR), I would like to express our gratitude for the support of the North American Hair Research Society, the European Hair Research Society, the Australasian Hair and Wool Research Society and numerous domestic and foreign pharmaceutical companies, whose generous contributions made the success of this meeting possible This, the largest triennial gathering of hair societies and the first of the new millennium, provided a unique opportunity for scientists and clinicians to exchange knowledge and build friendships. The meeting consisted of two keynote lectures, four workshops, plenary sessions, poster sessions and two luncheon seminars. We are also proud to announce that, with the aim of making the fruits of this very productive meeting available to the entire international community of dermatologists, we have undertaken the publication of all the abstracts and selected presentations delivered at the meeting in this Journal of Investigative Dermatology Symposium Proceedings. The Proceedings include a succinct summary by the chairperson of the workshops, as well as articles chosen from the plenary and poster sessions by the reviewers on the basis of their merit. It is my sincere hope that these proceedings will contribute to advancing our understanding of hair biology and hair diseases, and serve as a point of departure for even greater achievements in the field. Finally, I sincerely thank Dr. Susumu Takayasu, Oita Medical University, for his contribution to the organization of the scientific program of the meeting, and Dr. David A. Whiting, Baylor Hair Research and Treatment Center, Dr. Paul R. Bergstresser, The University of Texas Southwestern Medical Center and Dr. Ryoji Tsuboi, Tokyo Medical University, for their contributions in the time-consuming task of the final editing of all of the manuscripts.
