Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Hair disorders, expecialy scarring alopecia were diagnosed by scalp biopsy specimens in horizontal and vertical sections.(1-4) Data on hair density in Thais are lacking, although in Asians have more fewer hairs than whites.(5-7)Howevery, previous study from East Asian just had only one study and the data was more differently from West Asian and whites. Then this study was performed to evaluate hair density in Thais, and compared to previous study.
