Brief summary
Horizontal sectioning of scalp biopsy is a better method for evaluating hair disorders than vertical sectioning because it enables the quantitative examination of hair follicles at different stages. Without having the quantitative data of normal scalp hair counts as controls, it is impossible to evaluate scalp biopsies for hair disorders. In recent years, trichoscope is more popular in analysis of hair disease. It is less invasive and simple. The aim of this study is to understand the pros and cons of trichoscpoe.
