Accessory Structures of the Skin: Hair Growth and Types

1.8K
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...

Area of Science:

  • Dermatology and Computational Biology
  • Medical Image Analysis

Background:

  • Male androgenetic alopecia classification is subjective.
  • Trichoscopic data (hair density, diameter) offers quantitative potential.
  • Objective classification methods are needed for male androgenetic alopecia.

Purpose of the Study:

  • Develop a deep learning framework for automated trichoscopic image analysis.
  • Create a quantitative model to predict male androgenetic alopecia classification.
  • Enhance diagnostic accuracy and objectivity in hair loss assessment.

Main Methods:

  • Collected 2,910 trichoscopic images.
  • Developed a deep learning framework using convolutional neural networks.
  • Employed multiple ordinal logistic regression for quantitative modeling.

Main Results:

  • Established a deep learning framework for accurate hair density and diameter analysis.
  • Developed a quantitative model for predicting male androgenetic alopecia classification.
  • Demonstrated the framework's capability in objective trichoscopic analysis.

Conclusions:

  • The deep learning framework provides objective analysis of trichoscopic data.
  • The quantitative model aids in predicting male androgenetic alopecia classification.
  • This approach improves the objective assessment of male pattern hair loss.
