You should see a specialist for alopecia areata when you notice sudden, smooth, round patches of hair loss on your scalp or body that appeared within days or weeks rather than months. Misdiagnosis of hair loss type leads to wrong treatment in roughly 28% of cases, so getting expert evaluation early is one of the most important steps you can take.

Signs That Warrant a Specialist Visit
Not every instance of hair shedding requires a dermatologist. The following specific signs point to alopecia areata and should prompt a specialist consultation:
- Sudden round or oval bald patches on the scalp, beard, or eyebrows with smooth skin underneath
- Exclamation point hairs at the edges of patches (short, broken hairs that taper toward the base)
- Rapid progression with new patches appearing within weeks
- Nail changes such as pitting, ridging, or brittleness (present in 10 to 20% of patients)
- Family history of autoimmune disorders including thyroid disease, vitiligo, or lupus
If your hair loss follows a gradual receding pattern at the temples or slow thinning at the crown, this is more likely androgenetic alopecia (pattern baldness driven by DHT), which has a different treatment path.
Why Timing Matters
Early intervention in alopecia areata can make a real difference in outcomes. Patches that are treated within the first few months of onset respond better to corticosteroid injections than patches that have been present for a year or more. When the disease progresses from a few small patches to extensive loss (alopecia totalis or universalis), treatment becomes more complex and success rates drop.
The window for the best treatment response is typically within the first six months of noticing hair loss. Waiting longer does not necessarily make the condition permanent, but it does reduce the likelihood that first-line therapies will work on their own.
What to Expect at Your Specialist Appointment
A board-certified dermatologist will perform a clinical exam that includes:
- Visual inspection of patch shape, size, and distribution
- Dermoscopy using a magnified lens to look for yellow dots, black dots, and exclamation point hairs
- Pull test at the edges of patches to assess disease activity
- Blood work to check for related autoimmune conditions (thyroid, CBC, ANA)
Most diagnoses are made clinically without a biopsy. A scalp biopsy is only needed when the presentation is atypical or overlaps with other conditions like scarring alopecia.
When to Seek Urgent Care
Certain situations call for a faster specialist referral:
- Hair loss covering more than 50% of the scalp
- Rapid spread to eyebrows, eyelashes, or body hair within weeks
- Associated symptoms like joint pain, fatigue, or skin rashes (which may indicate a broader autoimmune issue)
- Hair loss in children under age 10, which can affect social development and may require pediatric dermatology input
