[METHODS OF MORPHOLOGICAL IDENTIFICATION OF THE HAIR FOLLICLE CYCLE PHASES]

Area of Science:

• Dermatology
• Histology
• Cell Biology

Background:

• Hair follicle (HF) structure and cyclic activity are crucial for hair growth.
• Understanding these changes is key to addressing hair loss and scalp conditions.

Purpose of the Study:

• To analyze the structural characteristics of hair follicles (HF) across different stages of the hair growth cycle.
• To provide detailed morphological descriptions of anagen, catagen, and telogen HFs.

Main Methods:

• Examination of autopsy scalp material from middle-aged women.
• Histological analysis of hair follicles (HF) in various planes.
• Illustration with photomicrographs and supplementary schemes.

Main Results:

• Detailed morphological descriptions of anagen, catagen, and telogen hair follicles (HF).
• Visual documentation of HF structures using photomicrographs.
• Schematic representations clarifying HF morphology during different cycle stages.

Conclusions:

• The study provides a comprehensive morphological analysis of hair follicle (HF) structures.
• This research offers valuable insights into the distinct characteristics of HFs during the anagen, catagen, and telogen phases.
• The findings contribute to a better understanding of hair follicle biology and cyclic changes.
