Beard alopecia areata affects up to 1.5% of men and often co-occurs with scalp alopecia areata, creating smooth, round patches in the beard that can expand, merge, or spontaneously resolve. Tracking beard patch boundaries over time with myhairline.ai provides objective documentation of whether patches are growing, stable, or responding to treatment.

Understanding Beard Alopecia Areata
Alopecia areata is an autoimmune condition where the immune system attacks hair follicles, causing them to shrink and stop producing visible hair. When this occurs in the beard, it typically presents as one or more smooth, coin-shaped bald patches on the cheeks, jawline, or chin.
Unlike androgenetic alopecia, which follows predictable patterns based on the Norwood scale, beard alopecia areata is unpredictable. Patches may appear suddenly, expand over weeks, or resolve without treatment. Some patients experience a single episode, while others have recurring flare-ups over years.
This unpredictability is exactly why tracking matters. Without objective data, it is impossible to know whether a patch is actively expanding, has stabilized, or is beginning to regrow until the change becomes obvious to the naked eye.
How Beard Alopecia Differs from Scalp Hair Loss
| Feature | Beard Alopecia Areata | Scalp Androgenetic Alopecia |
|---|---|---|
| Cause | Autoimmune attack on follicles | DHT sensitivity, genetic |
| Pattern | Random patches, unpredictable | Temple recession, vertex thinning |
| Progression | Can expand, merge, or spontaneously resolve | Progressive without treatment |
| Treatment | Corticosteroids, JAK inhibitors | Finasteride, minoxidil |
| Reversibility | Often resolves, may recur | Permanent without intervention |
| Tracking focus | Patch boundaries, expansion rate | Density percentage, Norwood stage |
Step 1: Photograph Your Baseline Patches
When you first notice a beard patch, document it immediately. Delays of even a few weeks mean lost data about the patch's initial size and rate of expansion.
For each patch, take a close-up photo with these conditions:
- Place a coin, ruler, or other fixed-size object next to the patch for scale reference
- Use consistent, even lighting (natural daylight works best)
- Photograph from the same distance each time (arm's length is a practical standard)
- Capture the patch straight-on, not at an angle that distorts the shape
If you have multiple patches, photograph each one individually and take one wider shot showing all patches in relation to each other. This helps track whether patches are merging over time.
Step 2: Set a Biweekly Scanning Schedule
Beard alopecia can change faster than scalp hair loss. Patches may double in size within 2 to 4 weeks during an active flare, or begin showing regrowth fuzz within a similar timeframe after treatment starts.
A biweekly (every 2 weeks) scanning schedule captures these changes at a granularity that monthly scanning would miss. Mark your calendar and take photos on the same day of each cycle.
At each scan, record:
- The approximate diameter of each patch (using your scale reference)
- Whether the patch borders appear sharp and defined (active) or soft and fuzzy (regrowing)
- Any new patches that have appeared since the last scan
- Any patches that have started showing vellus (fine, colorless) hair regrowth
Step 3: Log Treatments and Interventions
Beard alopecia treatment varies by severity, and your dermatologist may try several approaches. Log each treatment start date and dosage alongside your patch photos:
Intralesional corticosteroid injections: The first-line treatment for limited beard patches. Response rates range from 60% to 80%. Injections are typically repeated every 4 to 6 weeks. Track patch size before and 2 weeks after each injection session.
Topical corticosteroids: Applied daily to patches. Less effective than injections for beard alopecia but useful for mild cases or maintenance between injection sessions.
Topical minoxidil (5%): Used as adjunctive therapy to stimulate regrowth. Minoxidil produces moderate regrowth in 40% to 60% of scalp alopecia patients, and similar mechanisms apply to beard follicles.
JAK inhibitors: Newer systemic treatments like baricitinib and ritlecitinib show significant promise for moderate to severe alopecia areata. These are typically reserved for cases affecting large beard areas or multiple body sites.
By logging treatment dates in your tracking timeline, you create a cause-and-effect record. If a patch began shrinking 3 weeks after starting corticosteroid injections, that correlation is visible in your data.
Step 4: Track Patch Boundary Changes
The most important metric in beard alopecia tracking is patch boundary movement. At each biweekly scan, assess whether each patch is:
Expanding: The smooth border is moving outward. The edge may show exclamation-point hairs (short hairs that narrow at the base), which indicate active disease.
Stable: No change in patch size or shape between scans. This may indicate the immune attack has paused, but it does not guarantee resolution.
Regrowing: Fine, white or colorless vellus hairs appear within the patch first. Over weeks, these thicken and gradually regain pigment. Your tracking photos will show the patch filling in from the edges inward or from scattered points within the patch.
Merging: Two adjacent patches growing toward each other. Document the distance between patches at each scan. Merging patches create larger cosmetic concerns and may prompt your dermatologist to escalate treatment.
Your alopecia areata monitoring data should include all of these states to give your treatment team the full picture.
Step 5: Share Your Data with Your Dermatologist
Dermatologists typically see patients every 4 to 8 weeks. Between visits, your beard patches may go through significant changes that are invisible during a single office visit.
Bring your myhairline.ai tracking timeline to each appointment. Your dermatologist can use your data to:
- Compare patch sizes across visits without relying on memory or brief clinical notes
- Assess whether treatment is producing measurable change or if a switch is needed
- Identify patterns in flare-up timing that might correlate with stress, illness, or seasonal factors
- Document treatment response for insurance prior authorization if systemic treatments are needed
Learning how to document hair loss for your dermatologist makes your appointments more productive and ensures your concerns are supported by objective data rather than subjective description.
When Beard and Scalp Alopecia Co-Occur
Since beard alopecia areata frequently co-occurs with scalp involvement, tracking both sites simultaneously provides your dermatologist with a complete autoimmune activity profile. If your scalp patches are responding to treatment while your beard patches are not (or vice versa), this information guides treatment decisions.
Scalp alopecia areata is distinct from androgenetic alopecia. If you also have pattern hair loss, your tracking data will show the stable, predictable Norwood pattern (where grafts range from 800 to 1,500 at Stage 2 up to 5,500 to 7,500 at Stage 7) overlaid with the unpredictable autoimmune patches. Separating these two conditions in your tracking data is essential for accurate diagnosis and treatment planning.
