Accessory Structures of the Skin: Hair Growth and Types

Accessory Structures of the Skin: Hair Growth and Types

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:

Pediatric Research
Biomarker Collection
Developmental Psychology

Background:

Hair cortisol analysis is common in adults but lacks standardized protocols for infants.
Assessing physiological stress in infants requires reliable and ethical hair sample collection methods.

Purpose of the Study:

To develop and evaluate the acceptability and feasibility of a novel hair collection protocol for 12-month-old infants.
To address the absence of specific guidelines for infant hair sampling in scientific literature.

Main Methods:

A protocol for collecting hair samples from 12-month-old infants was developed.
Caregiver consent, infant tolerance, and practical collection challenges were assessed.
Five key lessons were identified to enhance the protocol's effectiveness and participant comfort.

Main Results:

The protocol achieved high caregiver consent (95.6%) and was feasible, with no attrition due to infant distress.
Two infants (4.4%) lacked sufficient hair, and one procedure was halted prematurely.
Lessons learned focused on infant positioning, caregiver reassurance, distraction techniques, careful handling, and precise weighing.

Conclusions:

The developed hair collection protocol is feasible and acceptable for 12-month-old infants.
This protocol fills a critical gap in pediatric research methodology.
The findings will enhance the reproducibility and efficiency of infant hair sample collection for future studies.
