OBJECTIVES: The objectives of this study were to determine whether there are significant differences regarding the number of hairs per unit area on the scalp skin and the front abdominal wall skin, and whether there are significant differences regarding the histomorphological parameters (hair diameter, thickness of the hair follicles and the distance between follicles) between terminal scalp hair and front abdominal wall vellus hair. STUDY DESIGN: The skin samples were qualitatively analyzed using a light microscope and quantitatively using a histomorphological analysis of the parameters measured with the help of computer programs. MATERIAL AND METHODS: The study was conducted on scalp skin samples (5 samples) and front abdominal wall skin samples (5 samples). The samples were histologically analyzed and photographed using an Olympus® C-5050 digital camera connected with the Olympus® BX-50 microscope. Histomorphometric parameters were measured using QuickPHOTO Pro computer program, and the data was analyzed using the Mann-Whitney U test. RESULTS: The morphological analysis of the samples showed significant differences in the structure of terminal and vellus hair and their distribution on the scalp skin and on the front abdominal wall skin. Histomorphometric analysis showed that the hair density was significantly higher, and the distance between follicles significantly lower in the scalp skin when compared to the abdominal wall skin (p=0,008), which is in accordance with known results. Even though the diameter of vellus hairs and follicle thickness were smaller than of the terminal hairs, this difference was not statistically significant. CONCLUSION: There are significant differences in the hair density and the distance between hair follicles on the scalp skin and the front abdominal wall skin.
