Hair Loss in Children
definition
Hair loss in children can impact their psychology, especially during school age. The severity depends on the child’s age and the underlying cause.
In infants, neonatal hair loss is normal and usually resolves without treatment. However, in toddlers and older children, excessive hair loss may indicate underlying issues. While most types of hair loss are not dangerous to overall health, they can affect a child’s self-confidence.
Diagnosis and timely intervention by a specialized dermatologist are critical for the proper management of hair loss and the prevention of future thinning problems. Effective treatments are available in most cases.
- Specialized Diagnosis using Trichoscopy and Trichogram for detailed scalp evaluation and identification of the exact cause of hair loss
- Customized and Individualized Treatments for every underlying cause
- Emphasis on early diagnosis and treatment to prevent future thinning and restore the child’s confidence
Etiology
Hair loss in children can be the result of a variety of causes, both acquired and congenital. The most common include:
Tinea Capitis: A fungal infection causing circular hair loss patches with flaking on the scalp. It is contagious and mainly seen in young children.
Alopecia Areata: An autoimmune disease where the immune system attacks hair follicles, creating round bald patches without broken hairs.
Trichotillomania: A habit where the child pulls or twists their hair due to stress, resulting in hair loss.
Telogen Effluvium: Occurs after physical or emotional stress, such as high fever or sudden weight loss. It disrupts the hair growth cycle, leading to significant shedding.
Nutritional Deficiencies, such as lack of iron, zinc, or biotin, or elevated vitamin A levels
Hormonal Disorders, e.g., hypothyroidism, which affect the hair growth cycle
Congenital Conditions, such as sebaceous nevus or congenital aplasia of the skin, preventing hair growth in certain areas
When to see a doctor
Hair loss in children may be concerning if it exceeds normal levels or is accompanied by other symptoms. Some indicators that a medical evaluation is needed include:
- Amount of Hair Loss: If the child is losing large quantities of hair or if the shedding increases over time, it may point to an underlying health issue
- Pattern of Hair Loss: If hair loss appears in a circular or oval shape, it may indicate alopecia areata
- Age: While some hair loss is normal in infants during the first months of life, hair loss in older children warrants attention
- Other Symptoms: Itching, redness, or pain along with hair loss may suggest another underlying condition
- Family History: A family history of hair loss may increase a child’s risk of developing similar issues
Diagnosis
Monitoring symptoms and timely intervention by a doctor are important for accurate diagnosis and treatment. The dermatologist plays a key role in understanding and managing childhood hair loss, offering specialized diagnosis and therapy.
The process starts with a detailed clinical examination of the scalp, during which medical history, stress levels, and nutritional habits are assessed. The following tests may be used for diagnosis:
Dermatoscopy – Trichoscopy
A magnified examination that allows analysis of the hair and scalp.
Trichogram
A digital analysis of scalp condition, including hair density and the proportion of hair in the anagen and telogen growth phases.
Scalp Biopsy
In more complex cases, a sample of scalp skin may be required for analysis by a pathologist.
Laboratory Blood Tests
To detect nutritional deficiencies or possible hormonal imbalances.
Hair loss in children is caused by multiple factors, so an accurate diagnosis by a dermatologist is essential. Depending on the cause, treatment may involve cooperation with other specialists, such as endocrinologists for hormonal issues or psychologists in cases of emotional stress or anxiety.
Treatment
Treatment of hair loss in children is tailored based on the underlying cause.
In cases of fungal infections, antifungal medications are prescribed, while in autoimmune conditions like alopecia areata, immunosuppressants or topical corticosteroids may be used. Additionally, supplements may be given for nutritional deficiencies or medications to halt genetic hair loss.
In all cases, early diagnosis through clinical examination and trichoscopy is crucial for determining the appropriate treatment plan for the child.
