Trichoscopic Findings in Normal Hair and Scalp in Children Under 17 Years

Area of Science:

• Dermatology
• Pediatric Trichology
• Medical Imaging

Background:

• Establishing normative data for pediatric hair and scalp parameters is essential for accurate diagnosis.
• Previous studies may lack comprehensive trichoscopic data across diverse pediatric age groups.
• Standardized reference values are needed to differentiate normal findings from pathological conditions.

Purpose of the Study:

• To determine and document normal trichoscopic values in a pediatric population.
• To establish a standardized framework for evaluating hair and scalp health in children.
• To provide a reference for identifying abnormal trichoscopic findings in various age groups.

Main Methods:

• A cohort of 750 healthy children of Malayalam speaking ethnicity was studied.
• Participants were categorized into six age groups, from neonates to 17 years.
• Trichoscopy was performed across multiple scalp regions using a digital dermoscope, analyzing hair shaft, follicular openings, and surrounding areas.

Main Results:

• Specific ranges for terminal:vellus hair ratios were documented for each age group and scalp region.
• Variations in these ratios were observed across different age strata.
• Comprehensive trichoscopic findings for various pediatric age groups were systematically recorded.

Conclusions:

• The study successfully summarized trichoscopic patterns for normal pediatric hair and scalp across different age groups.
• This provides a valuable reference for clinicians to accurately identify abnormal conditions.
• The established norms serve as a foundation for future research and clinical practice in pediatric trichology.
