Insights
Distinguishing the cause of pediatric hair loss is crucial for effective management. A thorough history, physical exam, and dermoscopy aid in diagnosing conditions like infections, genetic disorders, or autoimmune issues.
Area of Science:
- Pediatric Dermatology
- Trichology
Background:
- Hair loss is a common concern in infants and children, impacting them socially and emotionally.
- Identifying the cause is essential for appropriate management and guidance.
- Most pediatric hair loss is nonscarring.
Purpose of the Study:
- To review the differential diagnosis of hair loss in children.
- To emphasize the importance of accurate diagnosis for guiding patient management.
- To highlight common causes including infection, autoimmune conditions, nutrition, medications, trauma, and genetic disorders.
Main Methods:
- Diagnosis relies on a comprehensive patient history, including family history and medication use.
- A thorough physical examination of the hair, scalp, skin, and nails is critical.
- Dermoscopy or trichoscopy significantly improves diagnostic accuracy and speed.
Main Results:
- Physical examination and dermoscopy/trichoscopy are key diagnostic tools.
- Biopsies are rarely necessary for diagnosing pediatric hair loss.
- Classifying hair loss as congenital vs. acquired, focal vs. diffuse, and scarring vs. nonscarring aids diagnosis.
Conclusions:
- Accurate diagnosis of pediatric hair loss is achievable through careful history taking and physical examination, augmented by dermoscopy/trichoscopy.
- Distinguishing between various causes ensures optimal patient care and family guidance.
- Understanding the etiology allows for targeted interventions and management strategies.
Purpose Of Review:
Hair loss is common in infants and children and the ability to distinguish why a child is losing hair enables providers to distinguish hair loss that is related to infection, autoimmune conditions, nutrition, medications, trauma/traction, or underlying genetic disorders such as ectodermal dysplasias. Making these distinctions leads to best management and guidance for patients and their families.
Recent Findings:
Careful physical examination of the hair, scalp, skin, and nails coupled with dermoscopy or trichoscopy, or both, can yield more accurate and faster diagnosis. Biopsy is rarely needed in children for hair loss conditions.
Summary:
Hair loss, particularly on the scalp, can affect all ages and can impact patients socially and emotionally. The majority of hair loss in children is nonscarring. Diagnosis begins with a good history, including personal and family history, medication use, a thorough physical examination, and use of dermoscopy or trichoscopy, or both. With these, providers can begin to divide hair loss into congenital vs. acquired, and then further subdivide into focal vs. diffuse and scarring vs. nonscarring. Secondary change, including scale and erythema, can further help with diagnosis.
