Paediatric dermatologist for hair loss — finding the right specialist can make a significant difference to your child's diagnosis, treatment, and emotional wellbeing. Hair loss in children, medically termed alopecia, has many potential causes, from autoimmune conditions such as alopecia areata to fungal infections like tinea capitis. Each requires a tailored approach guided by a clinician experienced in childhood presentations. This article explains the common causes of hair loss in children, when a GP referral to a paediatric dermatologist is appropriate, what the assessment involves, which NHS treatments are available, and how to support your child's mental health throughout.

Common Causes of Hair Loss in Children and Young People

Alopecia areata is the most common cause of childhood hair loss, but tinea capitis, telogen effluvium, traction alopecia, and hair shaft disorders are also frequently encountered. Red flags such as a painful boggy scalp or scarring require urgent assessment.

Hair loss in children, known medically as alopecia, can arise from a wide range of causes, and identifying the underlying reason is essential before any treatment is considered. The most common cause in children and adolescents is alopecia areata, an autoimmune condition in which the immune system mistakenly attacks hair follicles, resulting in patchy, well-defined areas of hair loss on the scalp or elsewhere on the body. It affects approximately 2% of the population at some point in their lifetime and can begin in childhood.

Another frequently encountered cause is tinea capitis, a fungal infection of the scalp that is particularly prevalent in school-age children. It often presents with scaly, itchy patches and may cause broken hair shafts or areas of hair thinning. This condition is contagious and requires prompt antifungal treatment. A serious complication of tinea capitis is kerion — a painful, boggy, inflammatory swelling of the scalp that can cause scarring if not treated urgently.

Other causes include:

• Trichotillomania – a body-focused repetitive behaviour involving compulsive hair-pulling, which may or may not be associated with anxiety or stress

• Telogen effluvium – diffuse shedding triggered by illness, or significant emotional stress; iron deficiency (low ferritin) is a well-supported and testable nutritional contributor

• Traction alopecia – caused by tight hairstyles such as braids or ponytails; early intervention is important to prevent permanent scarring

• Thyroid disorders – both hypothyroidism and hyperthyroidism can contribute to hair thinning

• Loose anagen syndrome – a paediatric-specific condition in which hairs are easily and painlessly pulled from the scalp, most commonly seen in young girls with fair hair

• Hair shaft disorders – structural abnormalities such as monilethrix or trichorrhexis invaginata, which cause fragile or abnormally shaped hair shafts

• Adolescent androgenetic alopecia – pattern hair loss can begin in adolescence and should be considered in teenagers

Less commonly, hair loss may be associated with rare genetic conditions such as ectodermal dysplasia, or may be a side effect of certain medications, including chemotherapy agents. Nutritional deficiencies other than iron (such as zinc or vitamin D) are sometimes implicated, but testing for these should be guided by clinical suspicion and risk factors rather than performed routinely.

Red flags requiring urgent assessment include a painful or boggy scalp (suggesting kerion), pustules or crusting with fever, rapidly progressive or scarring hair loss, or any signs of scalp destruction. Parents and carers who notice unusual or progressive hair loss in their child should seek advice from their GP in the first instance, who can then determine whether onward referral is appropriate. Information on common causes is available from the British Association of Dermatologists (BAD) patient information leaflets and NICE Clinical Knowledge Summaries (CKS).

When to Seek a Referral to a Paediatric Dermatologist

Referral to a paediatric dermatologist is indicated for extensive or rapidly progressive hair loss, diagnostic uncertainty, failed first-line treatment, or suspected scarring alopecia. Kerion and signs of scalp destruction require urgent referral.

A GP will typically be the first point of contact when a child develops hair loss. In many straightforward cases — such as mild tinea capitis or telogen effluvium following a viral illness — the GP may be able to initiate treatment without specialist involvement. However, there are specific circumstances in which a referral to a paediatric dermatologist is strongly advisable.

Referral should be considered when:

• Hair loss is extensive, rapidly progressive, or affecting the entire scalp (alopecia totalis) or body (alopecia universalis)

• The diagnosis is uncertain after initial assessment

• First-line treatments have failed or the condition has recurred

• There are associated symptoms such as scalp inflammation, scarring, or skin changes that suggest a more complex dermatological condition

• Hair loss is causing significant psychological distress to the child or family

• A rare or inherited condition is suspected, including hair shaft disorders or congenital hypotrichosis in infants

• The child is immunosuppressed, as atypical presentations of scalp infections or other conditions may require specialist input

Urgent referral is warranted in the following situations:

• Kerion (painful, boggy, inflammatory swelling of the scalp) — a complication of tinea capitis that can cause permanent scarring if treatment is delayed

• Pustules, crusting, or fever alongside scalp hair loss

• Rapidly destructive scalp inflammation or signs of scarring alopecia

Scarring alopecia, though uncommon in children, warrants urgent referral as permanent follicle destruction can occur if treatment is delayed. Similarly, if trichotillomania is suspected, a multidisciplinary approach involving a paediatric dermatologist alongside a psychologist or CAMHS (Child and Adolescent Mental Health Services) team may be required.

In the UK, referrals are made through the NHS via the GP using the e-Referral Service. Waiting times can vary by region, and in cases of clinical urgency, GPs can request an expedited appointment. Private consultations with a paediatric dermatologist are also available for families who wish to be seen more quickly. Parents should not hesitate to return to their GP if symptoms worsen or new concerns arise while awaiting a specialist appointment.

Diagnosis and Assessment Methods Used in Children

Paediatric dermatologists use clinical history, scalp examination, and dermoscopy (trichoscopy) as primary diagnostic tools, with targeted blood tests, mycology, and scalp biopsy reserved for specific clinical indications.

When a child is seen by a paediatric dermatologist, the assessment process is thorough and tailored to be as comfortable and non-invasive as possible. The consultation typically begins with a detailed clinical history, including the onset and pattern of hair loss, any recent illnesses or stressors, dietary habits, family history of autoimmune or dermatological conditions, and current medications.

Physical examination of the scalp and hair is central to diagnosis. The dermatologist will assess the distribution and pattern of hair loss, the condition of the scalp skin, and the appearance of remaining hair shafts. A dermoscopy (trichoscopy) examination — using a handheld magnifying device with polarised light — is a non-invasive and well-tolerated tool that allows detailed visualisation of the scalp and hair follicles, helping to distinguish between different types of alopecia without the need for a biopsy in many cases. A hair pull test may also be performed to assess the ease of hair shedding.

Depending on the suspected diagnosis, the following targeted investigations may be arranged:

• Blood tests – investigations are selected based on clinical findings rather than performed as a routine panel. A full blood count (FBC) and ferritin level are commonly checked where nutritional deficiency or telogen effluvium is suspected. Thyroid function (TSH) is measured if thyroid disease is clinically suspected. Testing for zinc, vitamin D, or autoimmune markers such as antinuclear antibodies (ANA) is reserved for cases where there is a specific clinical indication

• Scalp scraping, hair samples, and fungal microscopy/culture – sent for mycology if tinea capitis is suspected; species identification guides the choice of antifungal treatment

• Wood's lamp examination – may be used to screen for certain species of tinea capitis (e.g., Microsporum species fluoresce under Wood's lamp, though Trichophyton species do not)

• Scalp biopsy – occasionally performed under local anaesthetic if scarring alopecia or an unusual presentation requires histological confirmation

Where trichotillomania is suspected, safeguarding considerations and psychological assessment should be part of the overall evaluation, and referral to CAMHS or a clinical psychologist may be appropriate.

Results from these investigations guide the treatment plan. The dermatologist will explain findings clearly to both the child and their parent or carer, ensuring the family understands the diagnosis and what it means for their child's long-term hair health. NICE CKS guidance on alopecia areata and tinea capitis provides further detail on recommended investigations in UK practice.

Treatment Options Available Through the NHS

NHS treatment depends on the underlying cause; options include topical or intralesional corticosteroids for alopecia areata, oral antifungals for tinea capitis, and psychological therapies for trichotillomania. Ritlecitinib is MHRA-authorised for severe alopecia areata in those aged 12 and over.

Treatment for childhood hair loss depends entirely on the underlying cause and is guided by the best available clinical evidence. It is important to note that not all hair loss requires active treatment — in cases of mild alopecia areata, for example, spontaneous regrowth occurs in the majority of children within 12 months, and a watchful waiting approach may be recommended initially.

For alopecia areata, commonly used NHS treatments include:

• Topical corticosteroids – applied directly to affected areas to reduce immune-mediated inflammation around the follicle

• Intralesional corticosteroid injections – more commonly used in older children and adolescents due to the discomfort involved

• Topical minoxidil – sometimes used to stimulate hair regrowth; it is important to note that minoxidil is not licensed for use in children and any use in this age group is off-label. It should only be considered under specialist supervision, with families informed of the limited evidence base and potential side effects, which include scalp irritation and unwanted facial or body hair growth (hypertrichosis)

• Contact immunotherapy (DPCP) – available in specialist centres for extensive or treatment-resistant alopecia areata

• JAK inhibitors – ritlecitinib (Litfulo) has received a UK marketing authorisation from the MHRA for the treatment of severe alopecia areata in people aged 12 years and over, and is initiated by a specialist. NHS availability in England is subject to NICE commissioning decisions; families should discuss current access with their dermatologist. Baricitinib is licensed for adults only and is not approved for use in children or adolescents with alopecia areata in the UK

For tinea capitis, oral antifungal therapy is the standard NHS treatment, as topical antifungals alone are insufficient to penetrate the hair shaft. The choice of agent is guided by the causative species identified on mycology:

• Terbinafine is the preferred treatment for Trichophyton species infections

• Griseofulvin remains an option, particularly for Microsporum species, where available; treatment typically continues for 6–8 weeks

• An antifungal shampoo (such as ketoconazole or selenium sulphide shampoo) is recommended for 2–4 weeks alongside oral treatment to reduce the risk of transmission to others

• Household contacts should be screened and treated if infected, and children should be advised they can remain in school once oral treatment has started

• Kerion requires prompt oral antifungal treatment; a short course of oral corticosteroids may be considered in specialist settings to reduce inflammation

For telogen effluvium, addressing the underlying trigger — such as correcting iron deficiency or managing stress — is the primary intervention, as the condition is generally self-limiting.

For traction alopecia, the most important intervention is modification of hairstyling practices to remove the source of tension. Early action is essential to prevent progression to permanent scarring.

In cases of trichotillomania, psychological therapies such as habit reversal training (HRT) or cognitive behavioural therapy (CBT) are recommended, often delivered through CAMHS.

Dosing for all medicines in children should be checked against the BNF for Children (BNFC). If your child experiences a suspected side effect from any medicine, this can be reported to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk. The MHRA and NICE continue to evaluate emerging therapies, and a paediatric dermatologist will always discuss the most current evidence-based options available.

Supporting Your Child's Wellbeing During Hair Loss

Hair loss can significantly affect a child's self-esteem and social confidence; practical support includes NHS wigs, charities such as the Little Princess Trust, and referral to CAMHS if anxiety or depression develops.

Hair loss can have a profound impact on a child's self-esteem, social confidence, and emotional wellbeing, particularly during the school years when peer relationships and self-image are especially important. Acknowledging these emotional challenges is a vital part of holistic care, and parents and carers play a central role in providing reassurance and support.

Open, age-appropriate conversations about the condition can help children feel less isolated and more in control. Encouraging children to ask questions and express their feelings — without minimising their concerns — fosters resilience. Schools can also be involved: many children benefit from their teacher being made aware of the situation so that any bullying or unkind comments can be addressed promptly and sensitively.

Practical support options include:

• Wigs and hairpieces – children with significant hair loss may be assessed for an NHS wig through their dermatology team or GP. NHS wigs are available as acrylic or human hair styles; children and young people may be exempt from charges depending on their age, circumstances, and local policy. Eligibility and provision vary, so it is important to check with your dermatology team or consult the NHS Business Services Authority (NHS BSA) guidance on wigs and fabric supports for up-to-date information on charges and exemptions

• The Little Princess Trust – a UK charity that provides free real-hair wigs to children and young people up to the age of 24 who have lost their hair through any medical condition or treatment

• Scalp camouflage products – may be available through some NHS dermatology departments, though provision varies by Trust; discuss with your dermatology team

• Support organisations – Alopecia UK offers resources, peer support groups, and guidance specifically for children and families affected by hair loss

• Psychological support – referral to CAMHS or a clinical psychologist should be considered if a child shows signs of anxiety, depression, or social withdrawal related to their hair loss

It is also important for parents to look after their own wellbeing. Watching a child experience hair loss can be distressing, and seeking support from healthcare professionals or peer networks is entirely appropriate. With the right medical care and emotional support, most children and young people are able to manage their condition effectively and maintain a good quality of life.
