Both conditions have “alopecia” in the name, and both cause hair loss. That is where the similarity ends. One is an autoimmune attack on healthy follicles. The other is a genetic sensitivity to a hormone. They look different, behave differently, and are treated differently.
Confusing them leads to the wrong treatment. A patient with alopecia areata given finasteride gets no benefit. A patient with androgenetic alopecia told it is “just stress” loses valuable time. This blog explains how to tell them apart.
If you are unsure which one you have, a scalp analysis at RECOMB gives a specific diagnosis.

What Each Condition Is
Androgenetic alopecia is genetic pattern hair loss. DHT binds to receptors in susceptible follicles and shortens each growth cycle, so hair becomes finer and shorter until the follicle stops producing visible hair. It is progressive and follows a predictable pattern.
Alopecia areata is an autoimmune condition. The immune system mistakes hair follicles for foreign tissue and attacks them, pushing them into a resting state. The follicle is usually not destroyed, which is why regrowth is possible.
How They Look Different
The pattern of loss is the first clue.
Androgenetic alopecia follows a pattern: receding temples and thinning crown in men, widening central parting in women. Loss is gradual, over years, and hairs become progressively finer.
Alopecia areata causes sudden, well-defined round or oval patches of complete smoothness. It can appear anywhere on the scalp, in the beard, or in the eyebrows. Onset is often rapid, over weeks.
The scalp within an areata patch is smooth and bald. In androgenetic alopecia, the affected area still has thin, short hairs.
What Trichoscopy Shows
Under magnification, the two conditions have different signatures.
Androgenetic alopecia shows hairs of varying thickness, with miniaturised hairs alongside normal ones. This variation is the hallmark.
Alopecia areata shows exclamation mark hairs, black dots, and yellow dots at follicle openings. These confirm active disease.
This single examination often settles the diagnosis in minutes, which is why trichoscopy matters.
Why Treatment Is Completely Different
Androgenetic alopecia needs ongoing management of the DHT mechanism: finasteride, minoxidil, and biological support such as GFC or PRP, with surgery when follicles are permanently lost.
Alopecia areata needs immune suppression. Intralesional corticosteroid injections are the usual first treatment for patchy disease, with topical treatments, and systemic options for extensive cases. Many patients regrow hair when treated early.
Using one condition’s treatment for the other wastes months and money. Finasteride does nothing for an autoimmune patch, and steroid injections do nothing for genetic miniaturisation.
Can Both Occur Together?
Yes. A patient with androgenetic alopecia can also develop alopecia areata. The result is a mixed picture that is easy to misread. Each component needs its own treatment, which is why a proper examination matters rather than assuming one diagnosis.
Why the Difference Matters for Hair Transplant
A transplant works for androgenetic alopecia once the pattern is stable. It is contraindicated in active alopecia areata, because the same immune attack can destroy the grafts, and surgery itself can trigger relapse.
Any patient with patchy loss who is offered a transplant without trichoscopy has not been properly assessed.

RECOMB’s Approach (2026)
At RECOMB Hair Transplant Centre, Surat, every hair loss patient has a trichoscopic assessment before any treatment is recommended. Dr. Krishna Bhalala’s dermatology background means autoimmune and pattern hair loss are diagnosed and managed in the same consultation.
We never recommend surgery for active alopecia areata, and we do not delay medical management in patients with confirmed androgenetic alopecia.
Final Takeaway
Androgenetic alopecia is a gradual, patterned, genetic condition. Alopecia areata is a sudden, patchy, autoimmune one. They need different treatments, and the correct diagnosis is the difference between regrowth and lost time.
Dr. Krishna Bhalala and Dr. Nilesh Kachhadiya conduct a limited number of personal consultations each week at RECOMB, Surat. If you are unsure which condition you have, this is where it is settled.
