Hair Loss in Children: Causes, Signs & What Parents Should Know

Hair loss is often thought of as a condition that only affects adults, but in reality, children can experience hair loss too — and when it happens, it can be distressing for both the child and their family.

If you’re noticing bald patches, excessive shedding, or thinning hair in your child, you’re not alone. Hair loss in children is more common than many realise and can be caused by a variety of underlying conditions — most of which are treatable.

In this blog, we’ll break down the main causes, signs to look out for, and next steps you can take to help your child.

Common Causes of Hair Loss in Children

🔹 1. Tinea Capitis (Scalp Ringworm)

A fungal infection of the scalp, tinea capitis is the most common cause of hair loss in children.

Signs:

  • Round bald patches with redness or scaling
  • Brittle, broken hairs ("black dot" appearance)
  • Itchy scalp or swelling

Treatment:
Antifungal medication (oral) and medicated shampoos. It's highly treatable, but early intervention is key to prevent spread.

🔹 2. Alopecia Areata

An autoimmune condition where the immune system mistakenly attacks hair follicles, causing sudden hair loss.

Signs:

  • Smooth, round bald patches
  • No scaling or redness
  • May also affect eyebrows or eyelashes

Treatment:
While there's no permanent cure, many children regrow hair spontaneously. Topical treatments like corticosteroids or minoxidil may be used under medical guidance.

🔹 3. Telogen Effluvium

Triggered by stress or a shock to the system, telogen effluvium causes more hairs than usual to enter the shedding phase.

Triggers include:

  • High fever or illness
  • Surgery
  • Emotional stress
  • Nutritional deficiencies

Signs:

  • Sudden shedding across the scalp
  • No bald patches, just thinning
  • Hair often regrows within 6–12 months

🔹 4. Trichotillomania (Hair Pulling Disorder)

A psychological condition where the child repeatedly pulls out their hair, often due to stress, anxiety, or habit.

Signs:

  • Uneven hair patches or broken hairs
  • Hair loss on eyebrows/lashes
  • Associated with emotional distress

Treatment:
Behavioural therapy is usually recommended, sometimes alongside psychological support.

🔹 5. Nutritional Deficiencies

Inadequate levels of iron, zinc, biotin, and vitamin D can cause generalised hair thinning in children.

Treatment:
A doctor may recommend blood tests and tailored supplements or dietary adjustments.

When Should You See a Doctor?

If your child is experiencing persistent or noticeable hair loss, it’s best to consult a GP or dermatologist. They may carry out:

  • Scalp examination
  • Blood tests
  • Fungal culture or biopsy
  • Discussion of emotional or behavioural factors

Early diagnosis is key to successful treatment — and can help ease your child’s anxiety about changes in their appearance.

Supporting Your Child Emotionally

Hair loss can affect a child’s self-esteem and social confidence, especially at school or during social development. Here's how you can help:

  • Stay calm and reassuring – Let them know it's not their fault and there are solutions.
  • Be open with communication – Answer questions honestly, without alarm.
  • Protect them from teasing – Speak to teachers if needed and create a supportive environment.
  • Consider gentle hair accessories or hats – If appropriate, make these part of a positive routine.
  • Seek professional emotional support – A child therapist can help if the emotional impact is significant.

Conclusion: Most Cases Are Treatable

While seeing your child lose their hair can be worrying, many forms of childhood hair loss are temporary and treatable. The most important thing is to act early, understand the underlying cause, and provide the right medical and emotional support.
