The reliability of horizontally sectioned scalp biopsies in the diagnosis of chronic diffuse telogen hair loss in women.

Background: Chronic diffuse telogen hair loss is common in women. Paired 4-mm punch biopsy from the vertex scalp for horizontal and vertical sectioning is commonly used to distinguish between chronic telogen effluvium (CTE) and female pattern hair loss (FPHL). FPHL is now the favored term for androgenetic alopecia in women.

Morphological approach to hair disorders.

The Workshop on the morphological approach to hair disorders brought together a group of clinicians involved in hair biology research. Six speakers spoke on a range of topics that can be grouped broadly into a central theme. It summarizes the evolution of medical research.
