Alopecia areata, totalis and universalis
An autoimmune condition, not a hair-care failure. The follicle is switched off rather than destroyed — which is why regrowth remains possible years in, and why nobody can promise you when.
At a glance

- Autoimmune, non-scarring hair loss
- Follicle

- No — but regrowth is common and can be substantial
The follicle is asleep, not gone.
In alopecia areata the immune system attacks the hair follicle and stops it producing a shaft. It does not scar it. That distinction is the single most important fact about this condition, because it means the machinery is still there — and regrowth remains biologically possible even after years without hair.
It also explains the shape of the disease. Round, sharply defined patches with normal skin inside. Sometimes short broken hairs at the edge. Often pitting or ridging of the nails, which is the clue that most reliably separates it from the other causes of a bald patch.
Where it spreads to the whole scalp it is called alopecia totalis; where it takes body hair, eyebrows and lashes too, alopecia universalis. Those are the same disease at greater extent, not different diseases — but they behave less predictably and they are harder to treat.
What is usually tried, and when
| Presentation | Commonly used | What to expect |
|---|---|---|
| A few small patches | Topical or intralesional steroid | Many regrow, some without treatment at all |
| Multiple or enlarging patches | Intralesional steroid, topical immunotherapy | Slower; may need several cycles |
| Rapidly spreading disease | Systemic therapy under supervision | Aimed at halting progression first |
| Alopecia totalis | Systemic therapy, immunotherapy | Less predictable; response varies widely |
| Alopecia universalis | Systemic therapy, immunotherapy | The hardest group; honest expectation-setting matters most here |
| Eyebrows and lashes | Site-specific treatment | Often treated alongside, not after |
Which of these applies to you is a clinical decision after examination, and several carry monitoring requirements. Nothing on this page is a prescription — it is what the options are, so you can ask about yours.
Nobody can tell you when it will regrow.
Alopecia areata relapses and remits on its own. A patch can regrow during treatment that did nothing, and a treatment that worked once can do nothing the next time. That unpredictability is the disease, not a failure of the doctor, and it is why any clinic quoting you a timeline for regrowth is quoting a number it does not have.
What can honestly be offered is this: an accurate diagnosis, the treatment appropriate to your extent and rate of spread, screening for the thyroid and other autoimmune conditions that travel with it, and a review schedule that changes the plan when it is not working rather than continuing it out of momentum.
How a video consultation worksExtent and speed guide treatment
A few stable patches and rapidly spreading disease are not the same problem and are not treated the same way.
Screened alongside
Thyroid disease, vitiligo and other autoimmune conditions occur together often enough to be looked for.
What makes a first alopecia consultation useful.
- Photographs of every patch, in daylight, with a size reference
- When it started and whether it has spread since
- Your nails — photograph them; pitting is diagnostic information
- Previous treatment, with dates and what happened
- Thyroid results if you have had them
- Family history of autoimmune conditions
Patients travel for this, and often do not need to
Alopecia areata is one of the conditions best suited to a first consultation over video: the diagnosis is largely visual, the bloods can be done locally, and much of the treatment can be supervised remotely. Send photographs on WhatsApp before you plan a journey.
Alopecia areata
Can alopecia areata be cured?
No. It is an autoimmune condition that relapses and remits, and no treatment removes that tendency. What treatment does is encourage regrowth and, in rapidly spreading disease, try to halt the spread. Many people regrow substantially; some do not, and that is said plainly rather than left to be discovered.
Will my hair grow back?
It may — the follicle is not destroyed, so regrowth stays possible even after years. Nobody can tell you when, or how completely, and a clinic that offers you a timeline is offering a number it does not have.
What is the difference between areata, totalis and universalis?
Extent. Areata is patchy loss; totalis is the whole scalp; universalis is scalp and body hair including eyebrows and lashes. Same disease, greater extent, less predictable behaviour.
Is it caused by stress?
Stress is reported as a trigger by many patients and may contribute, but alopecia areata is an autoimmune condition with a genetic component. It is not caused by poor hair care, oil, shampoo or diet.
Is it contagious?
No. It cannot be passed to anyone by contact of any kind.
Can I be treated for this from outside Hyderabad?
Often, yes. The diagnosis is largely visual, bloods can be done locally, and much of the treatment can be supervised over video with reviews on WhatsApp. Send photographs first and you will be told whether a visit adds anything.
