Alopecia areata is the most common cause of hair loss in children, affecting approximately 1 in 1,000 kids before age 16. Tracking patch boundaries and treatment response gives parents and pediatric dermatologists the data needed to make informed treatment decisions and monitor disease progression over time.
Why Tracking Is Different for Children
Children's alopecia areata behaves differently from adult cases in several important ways.
| Factor | Children | Adults |
|---|---|---|
| Spontaneous remission rate | 50% within 1 year | 34% within 1 year |
| Recurrence rate | Higher (up to 85%) | Moderate (50-60%) |
| Emotional impact | Affects school and social development | Affects professional and social life |
| Treatment options | Limited (age restrictions on medications) | Full range including systemic drugs |
| Compliance challenge | Child may resist photography | Self-directed |
The higher spontaneous remission rate in children means your tracking data may show natural improvement without intervention. Documenting this pattern prevents unnecessary treatment escalation.
Setting Up an Age-Appropriate Tracking Protocol
Step 1: Explain the Process to Your Child
Children cooperate better when they understand what is happening. Explain that you are taking pictures to help their doctor see how their hair is doing. For younger children (ages 4 to 8), frame it as a regular check-up activity. For older children and teens, involve them in the process so they feel a sense of control over their condition.
Step 2: Establish a Comfortable Routine
Choose a specific day and time every 2 weeks for photography sessions. Keep sessions short, under 5 minutes. Use the same room with consistent lighting. Having a favorite activity or small reward afterward helps younger children associate the process positively.
Step 3: Capture Baseline Photos
Photograph each patch individually, plus overall scalp views from above, front, and sides. Place a coin next to each patch for scale reference. For children with longer hair, gently part the hair to expose patch edges completely.
Record:
- Number of patches
- Approximate diameter of each patch in centimeters
- Patch locations (use a simple head diagram)
- Presence of exclamation mark hairs (broken, tapered hairs at patch edges that indicate active disease)
- Presence of vellus hairs within patches (a positive regrowth sign)
Step 4: Log Treatments and Triggers
Create a simple treatment log:
| Date | Treatment Applied | Dose/Frequency | Notes |
|---|---|---|---|
| Week 0 | Topical clobetasol 0.05% | Once daily to patches | Baseline, 3 patches |
| Week 2 | Topical clobetasol 0.05% | Once daily to patches | No change observed |
| Week 4 | Topical clobetasol 0.05% | Once daily to patches | Vellus hairs in largest patch |
Also note potential triggers: recent illness, school stress, seasonal changes, or dietary shifts. These observations help identify patterns over multiple flare cycles.
Step 5: Monitor Every 2 Weeks
At each session, photograph the same patches from the same angles. Upload to myhairline.ai for AI-assisted boundary comparison. Look for three key indicators:
- Patch size change: Expanding, stable, or shrinking
- New patches: Any new areas of hair loss
- Regrowth signs: Vellus hairs, pigmented stubble, or full terminal hairs returning
Treatment Options by Age Group
Ritlecitinib (Litfulo) is the first JAK inhibitor approved for alopecia areata in patients aged 12 and older. This approval changed the treatment landscape for adolescents, but options for younger children remain more conservative.
| Age Group | First-Line Options | Second-Line Options | Tracking Focus |
|---|---|---|---|
| Under 6 | Topical corticosteroids, observation | Topical minoxidil (off-label) | Patch boundary size, spontaneous regrowth |
| 6 to 11 | Topical corticosteroids, topical immunotherapy | Intralesional injections (if tolerated) | Treatment response by patch, new patch development |
| 12 to 17 | Topical corticosteroids, ritlecitinib | Intralesional injections, baricitinib | Systemic response across all patches |
Tracking data for each age group supports different clinical decisions. For younger children, the focus is on documenting whether watchful waiting is appropriate. For adolescents, tracking response to JAK inhibitors helps optimize dosing and continuation decisions.
Interpreting Your Child's Tracking Data
Positive Response Pattern
Patch boundaries shrink by 20% or more over an 8-week period. Vellus hairs appear within patches and gradually thicken into terminal hairs. No new patches develop. This pattern supports continuing the current treatment.
Stable Pattern
Patches remain the same size with no expansion or regrowth. This may indicate the condition is inactive but not yet resolving. Your dermatologist may recommend continuing current treatment for another cycle before changing approach.
Progressive Pattern
Existing patches expand, or new patches appear during treatment. If total scalp involvement increases, your tracking data provides the documentation needed to discuss treatment escalation. For children aged 12 and older, this data may support starting a JAK inhibitor.
Preparing for Dermatology Appointments
Bring your tracking data to every appointment. A visual timeline showing:
- Patch size changes over 3 to 6 months
- Treatment dates and types
- Any observed triggers or patterns
- Regrowth documentation
This data is especially valuable for pediatric dermatologists who may see your child only every 3 to 6 months. Between visits, your tracking fills the gap and prevents treatment decisions based on a single snapshot.

Start Tracking Your Child's Progress
Upload your first set of scalp photos to myhairline.ai/analyze to establish a baseline measurement. Consistent tracking every 2 weeks builds the dataset that helps your child's dermatologist make the best treatment decisions.
