How do I know if I have Alopecia?

Alopecia is a broad term for hair loss, which can range from temporary shedding to permanent autoimmune-mediated patches. You should investigate Alopecia if you notice unexplained thinning, circular bald patches, or sudden hair loss that significantly exceeds the normal shedding of 50–100 hairs per day.

What are the early signs of Alopecia?

The earliest signs of Alopecia often depend on the specific type. Alopecia areata typically presents as smooth, round, coin-sized patches of hair loss on the scalp, while androgenetic alopecia (pattern baldness) involves a gradual thinning of hair at the crown or a receding hairline. If you notice increased hair on your pillow or in the shower drain, or if your scalp feels tender or itchy before hair loss occurs, these can be early indicators of an underlying condition.

How can I perform a self-assessment?

Monitor your hair growth patterns over several weeks. Look for these specific changes:

• Symmetry: Are patches appearing on both sides of the head?


• Texture changes: Does the hair surrounding the area feel brittle or appear miniaturized?


• Scalp health: Check for redness, scaling, or inflammation, which may suggest inflammatory forms of Alopecia.


• Daily loss: Keep a loose log of how much hair you lose during washing or brushing.

When should I see a doctor and what tests are needed?

If your hair loss is sudden, patchy, or accompanied by systemic symptoms like fatigue or joint pain, schedule an appointment with a dermatologist. Ask your physician about a "pull test" to assess hair fragility and request blood work to rule out triggers, such as thyroid dysfunction, iron deficiency (ferritin levels), or autoimmune markers. Diagnostic Alopecia evaluations may also include a scalp biopsy to determine if the hair follicles are scarred or merely dormant.

What are the red flags for urgent care?

Seek medical attention promptly if your Alopecia is accompanied by a painful, crusting, or bleeding scalp, or if you experience rapid, total body hair loss. These symptoms may indicate an underlying systemic illness or severe inflammatory condition requiring immediate intervention.
