Yes, hair loss in children can be a form of alopecia, and while it is often distressing for both the child and the parent, many causes are treatable or temporary. In children, the most common forms of hair loss are alopecia areata, fungal infections, and physical trauma to the hair follicle. In the UK, healthcare pathways for children are specifically designed to address both the physical symptoms and the psychological impact, with clear criteria for when a GP should refer a child to a specialist paediatric dermatologist.

Common Causes of Childhood Hair Loss
Hair loss in children rarely follows the genetic patterns seen in adults. Instead, it is typically reactive or related to the immune system.
- Alopecia Areata: This is an autoimmune condition where the body attacks the hair follicles, leading to smooth, round bald patches. It is one of the most frequent causes of sudden hair loss in children.
- Tinea Capitis (Scalp Ringworm): This is a fungal infection that is highly contagious among children. It often presents with scaly patches, “black dots” (broken hairs), and sometimes swollen lymph nodes.
- Telogen Effluvium: Just like adults, children can experience diffuse thinning after a high fever, severe illness, or significant emotional stress.
Behavioural and Physical Causes
Sometimes, hair loss in children is caused by external physical pressure or repetitive behaviours.
- Traction Alopecia: This is caused by tight hairstyles, such as braids or ponytails, that pull on the hair roots. It is commonly seen along the hairline.
- Trichotillomania: This is a behavioural condition where a child compulsively pulls out their own hair. The patches are usually irregular in shape and contain hairs of varying lengths.
In the UK, management of trichotillomania often involves a multi disciplinary approach, including support from paediatric mental health services (CAMHS) to address the underlying impulse.
The Initial GP Assessment
If you notice your child is losing hair, the first step in the UK is an appointment with a GP. The doctor will perform a physical examination and may use a dermatoscope to look for specific signs, such as “exclamation mark” hairs (typical of alopecia areata) or fungal spores.
The GP may also order blood tests to rule out iron deficiency or thyroid issues, although these are less common causes in otherwise healthy children. According to NICE guidelines, if the cause is clearly identified as a simple fungal infection or a small patch of alopecia areata, the GP may begin treatment in the primary care setting.
When is a Special Paediatric Referral Needed?
While many cases are managed by a GP, certain clinical scenarios require the expertise of a paediatric dermatologist. You should request a specialist referral if:
- The Diagnosis is Unclear: If the GP cannot definitively identify the cause of the loss.
- Extensive Loss: If the child is losing more than 50 percent of their scalp hair or if eyebrows and eyelashes are involved (alopecia totalis).
- Signs of Scarring: If the scalp looks red, inflamed, or if the skin appears smooth and shiny without visible pores.
- Treatment Failure: If first line treatments (such as topical steroids or antifungals) have not worked after several months.
- Very Young Age: Hair loss in infants or toddlers often requires specialist review to rule out congenital or rare genetic conditions.
Conclusion
Hair loss in children can indeed be a form of alopecia, most commonly alopecia areata, but it can also be caused by infections or behavioural habits. While a GP is the first point of contact for an initial assessment and blood tests, a specialist paediatric referral is essential for extensive loss, suspected scarring, or cases that do not respond to basic treatment. In the UK healthcare system, the priority is to provide an accurate diagnosis while supporting the child’s emotional needs. By acting early and seeking the appropriate specialist care, parents can ensure their child receives the most effective treatment for their specific condition. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Is alopecia areata in children permanent?
In many children, the hair grows back on its own within a year. However, the condition can be unpredictable, and some children may experience future flare ups.
Can my child catch hair loss from another child?
Only if the cause is a fungal infection like tinea capitis (ringworm). Alopecia areata and trichotillomania are not contagious.
Does stress cause children to lose their hair?
Yes, significant stress can trigger telogen effluvium or worsen alopecia areata, but it is rarely the only cause.
What is a “kerion”?
A kerion is a severe, inflammatory reaction to a fungal infection that looks like a soft, pus filled lump. It requires urgent medical treatment to prevent scarring.
Can a child wear a wig or hairpiece on the NHS?
Yes, children with significant permanent or long term hair loss are often eligible for synthetic or human hair wigs through the NHS.
Should I change my child’s diet?
Unless a blood test has confirmed a specific deficiency like low iron, changing the diet is unlikely to stop medical forms of alopecia.
How can I help my child’s school understand?
Many UK charities provide “school packs” that help teachers and classmates understand alopecia, reducing the risk of bullying or social isolation.
