Summary
Temporal triangular alopecia (TTA) is a non-scarring hair loss condition that usually appears in early childhood as a small triangular or oval patch of thinning hair at the temples. It is not caused by hair pulling, infection, or poor care. With accurate diagnosis, families can be reassured, unnecessary treatments avoided, and scalp health properly supported.
Temporal Triangular Alopecia in Children: A Non-Progressive Cause of Localised Hair Loss
By Shuna Hammocks, MIT, Consultant Trichologist
Temporal Triangular Alopecia (TTA) is a harmless, non-scarring condition that most commonly presents in children as a small, well-defined patch of reduced hair density at the temple. It is often noticed in early childhood and may be described by parents as an area that has “always been there”.
Although understandably worrying when first observed, Temporal Triangular Alopecia does not indicate illness, nutritional deficiency, or poor hair health, and it does not worsen over time.
At Shuna Hammocks Trichology, families across West Sussex receive careful, child-centred assessment to ensure an accurate diagnosis and supportive management plan.
What is Temporal Triangular Alopecia?
In children, Temporal Triangular Alopecia typically appears as a triangular, oval or lance-shaped patch of reduced hair density, usually affecting one side of the fronto-temporal hairline. Less commonly, both temples may be involved.
Despite sometimes being called Congenital Triangular Alopecia, the condition may not be obvious at birth.
It often becomes noticeable:
- In toddlerhood or early childhood
- When the surrounding hair becomes thicker
- During growth spurts or hairstyle changes
Common features seen in children include:
- A stable, clearly defined patch that does not enlarge
- Normal scalp skin, with no redness, scaling or scarring
- Presence of fine, soft (vellus) hairs within the area
- No itching, pain or sensitivity
What Causes Temporal Triangular Alopecia?
TTA is considered a developmental condition rather than an illness.
Current understanding suggests:
- Hair follicles in the affected area develop differently
- It is not caused by stress, pulling, infection, or nutritional deficiency
- It is not contagious
- In some cases, there may be a mild genetic component, but most children have no family history.
The Importance of Accurate Diagnosis in Children
Temporal Triangular Alopecia is frequently misdiagnosed in children, most commonly as:
Misdiagnosis can lead to:
- Unnecessary investigations
- Inappropriate topical treatments
- Increased anxiety for parents and children
A trichological assessment, including dermoscopic examination, allows for accurate identification. In TTA, dermoscopy shows:
- Intact follicular openings
- Miniaturised follicles producing vellus hairs
- No inflammation or scarring
Correct diagnosis is essential to reassure families and avoid unnecessary intervention.
Management and Support for Families
Because Temporal Triangular Alopecia is a benign condition, medical treatment is generally not recommended or required for children.
Our Management Approach Focuses On:
- Evidence-Based Reassurance: Confirming the non-progressive nature of the condition.
- Avoidance of Harsh Chemicals: Preventing the use of unnecessary topical steroids or growth stimulants that are ineffective for vellus follicles.
- Cosmetic Guidance: Discussing gentle hairstyling adjustments as the child grows to help with confidence.
- Long-term Monitoring: While surgical options (like hair transplants) can be considered in adulthood, they are never appropriate for pediatric patients.
Can Temporal Triangular Alopecia Be Treated?
No medical treatment is required for Temporal Triangular Alopecia, as the condition is benign and does not indicate ill health.
Management focuses on:
- Education and reassurance for families
- Scalp and hair care guidance
- Monitoring over time, if needed
- Support with cosmetic concerns as the child grows
In selected cases, families may explore cosmetic or medical options later in life, but this is never urgent in childhood.

Frequently Asked Questions
Is Temporal Triangular Alopecia painful or uncomfortable?
No. Temporal Triangular Alopecia does not cause pain, itching, tenderness or scalp irritation. The scalp skin remains healthy and comfortable, and children are usually unaware of the affected area.
Is it caused by hair pulling or tight hairstyles?
No. Unlike traction alopecia, Temporal Triangular Alopecia is not caused by hair pulling, tight hairstyles or grooming practices. It is a developmental condition related to how hair follicles form in that specific area.
Will my child lose more hair elsewhere?
No. Temporal Triangular Alopecia is a localised condition and does not spread. It does not affect overall hair growth, scalp health, or hair density in other areas of the scalp.
Can the hair grow back naturally?
Spontaneous regrowth is unlikely because the area contains fine vellus hairs rather than fully developed terminal hairs. However, the condition remains stable and does not worsen over time.
Should my child see a trichologist?
Yes. A trichologist can confirm the diagnosis, rule out other childhood hair loss conditions, and provide clear reassurance. This helps avoid unnecessary treatments and ensures guidance is appropriate for your child’s age and development.
