"Science begins with measurement“, Dmitry Mendeleev.

Currently Dermatoscopy firmly holds the position of one of the most affordable and effective methods of diagnosis in Dermatology. As a science Dermatoscopy received first impact to development in 1663, when Johan Christophorus Kolhaus investigated small vessels of the nail bed with a microscope. In 1920 I. Saphier introduced the term of "Dermatoscopy" and produced detailed description of the possible assessment methods of capillaries in the lower lip by means of Dermatoscope. In 1989 R. Soyer revealed a correlation of Dermatoscopic criteria with underlying histopathological structures. The first conference on Dermatoscopy was held in 1989 in Hamburg, Germany. In 2001 the first World Dermatoscopy Congress took place in Rome.

Quite recently Dermatoscopy has advanced into another Dermatology field – Trichology. In 1993 Kossard and Zagarella published a case of scarring alopecia in 42-year-old African-American woman and described its diagnostic Dermatoscopic criteria associated with perifollicular fibrosis visualization. First videodermatoscopic criteria of androgenetic alopecia severity and ways of dynamic monitoring of the therapy efficacy were described In 2005. Since 2006 Rudnicka introduced the term "Trichoscopy" which has been applied in assessing the condition of the hair, scalp, eyebrows, eyelashes with videodermatoscopic technology. The authors have shown that by means of Trichoscopy it is quite simple to identify such conditions as Moniletrix and other genetic hair diseases. The first Dermatoscopy atlas of hair and scalp was released by A. Tosty in 2007. In 2008 Rudnicka and other coauthors described the diagnostic Trichoscopic criteria of Alopecia Areata with atypical course of progression, when it is difficult to provide clinical evaluation based on clinical symptoms. In authors opinion the leading signs are "yellow spots", cadaverized hair ("black spots"), exclamation mark hair (up to 1 mm length) and dystrophic hair. They also described Vellus hair in focal alopecia sites. Perifollicular fibrosis signs in form of “white spots” may be observed in extended courses of this form of alopecia.

As for Alopecia Androgenetica – this condition is easily diagnosed at first site in most cases due to its typical clinical picture. But practice has shown that many professionals tend to confuse a concept of chronic diffuse Telogen hair loss and androgenetic alopecia in women. The most accurate methods of differential diagnosis of these conditions besides Trichoscopy are phototrihograms. Carrying out the technique of phototrichogram with contrast and tattoo can rapidly increase the reliable assessment of the treatment dynamics. This has been successfully applied in both the scientific and simply routine activities of Trichologists. Specialists in the diagnosis and treatment of hair diseases almost always need to have reliable information on hair density (number of hairs per square cm) in different areas of the scalp, hair diameters, ratio of terminal and thinning (Vellus-like) hair, percentage of growing and shedded hair, etc. To obtain reliable results of these studies the most frequently used methods are Trichoscopy and phototrihogram.

. “Science begins with measurement"- these words belong to famous Russian scientist Dmitry Mendeleev. The most active development of Trichology in Russia began in late 90s of the last century. With Trichoscopy introduction and increasing demand for precise measurement and evaluation of various parameters related to hair normal and pathological conditions the need for specific diagnostic and analytical software tool to accommodate all these issues has been arising gradually. The professional computer program TrichoScience © was developed and presented in Moscow in 2004 by TRILOGIC, the company established by Medical Doctors – Dermatologists, that has always been at the cutting edge of Trichology in Russia and is aimed to provide the latest information and up-to-date scientific knowledge in this field. Created by the medical professional team lead by Dr. Vladislav Tkachev, MD, PhD, vice-chairman of the Trichological Society of the National Alliance of Dermatologists and Cosmetologists of Russian Federation, the first version of TrichoScience © combined all possible specific studies in Trichology accumulated by that time. Due to quick progress in the hair and scalp disorder studies and rapid advances in the diagnostics of hair diseases fields, the program keeps gradually updating and expanding with the most new specific Trichologic techniques and analysis. By present time the program has got a total of eight versions and comes in Russian and English languages (2011). Besides Russia, the TrichoScience © software by now has been also successfully used in United States, European Union and Israel. The first international introduction of the computer program was performed by its creating team in September of 2008 at the European Academy of Dermatology and Venereology 17^th EADV Congress in Paris, France. The latest version of the software has been presented in July of 2011 at the European Hair Research Society EHRS 15^th Annual Meeting in Jerusalem, Israel. The special sign of TrichoScience © software professional worldwide recognition is a fact, that Lexington International LLC, the developer of internationally known Hair Max laser brush in United States, has evaluated almost all of the hair analysis software systems and chose the TrichoScience © as the most comprehensive and accurate computer program to be used at the time for control of numerous clinical studies performed to prove laser efficacy in hair loss treatment for FDA 510(k) medical device clearance approval.
