Alopecia Areata
Dermatologist-led overview of alopecia areata, a common cause of patchy hair loss.
View AAD reference ›Bald patches are different from ordinary hair fall. The most common cause is alopecia areata, an autoimmune condition, but patches can also be a fungal scalp infection, traction from tight styles, or a scarring alopecia — and these are treated in completely different ways. Some can spread or cause permanent loss if mismanaged. So the safest first step is a dermatologist's diagnosis. Hairsncares helps you screen the patches with an AI checker and points you to the right specialist care.
Illustrative sample only. AI screening cannot diagnose and does not replace a dermatologist's assessment.
There is no single best treatment, because patchy hair loss has several very different causes. Smooth round patches are usually alopecia areata (autoimmune); scaly, red or broken-hair patches may be a fungal infection (tinea capitis), especially in children; and shiny, scarred patches may be a scarring alopecia. Each is treated differently, and some can spread or cause permanent loss. So the best and safest first step is a dermatologist's diagnosis — not buying products. An AI patch check can screen and flag urgency, and gentle products may give supportive or cosmetic help alongside medical treatment.
Round bald patches are diagnosis-first and should be reviewed for alopecia areata, fungal infection or scarring causes.
AI Summary
Patchy hair loss is one possible hair-loss pattern or trigger. The right next step depends on whether hair is shedding from the root, breaking from the shaft, thinning in a pattern, falling suddenly, persisting for months or appearing in patches.
This page is educational and screening-oriented. It does not diagnose, prescribe or guarantee results. Use the AI Hair Test to organise symptoms, and consult a dermatologist if symptoms are severe, persistent, patchy, painful or progressive.
Best next step: identify the pattern, check likely triggers, review red flags, then choose a routine, product pathway or doctor consultation safely.
Patchy hair loss means hair is lost in distinct patches — often round or oval bald spots — rather than evenly across the scalp or in a receding pattern. This distribution is an important clue, because the conditions that cause patches are mostly medical and quite different from ordinary hair fall.
The most common cause is alopecia areata, an autoimmune condition that produces smooth, round bald patches. But a scaly, red or broken-hair patch may be a fungal scalp infection (tinea capitis), especially in children; tight hairstyles can cause traction alopecia at the edges; and a shiny, scarred patch may signal a scarring alopecia, which can cause permanent loss. Because the right treatment — and the urgency — depends entirely on which of these it is, patchy hair loss should be diagnosed by a dermatologist rather than self-treated.

Take Patch CheckThese features help describe a patch — and some point to causes that need prompt dermatologist care.
Round or oval bald patch with smooth skin
Patch appearing suddenly over days to weeks
Short broken hairs at the edge (exclamation-mark hairs)
Scaling, redness or pus (possible infection)
Small black dots in the patch (possible fungal)
Shiny, smooth, scarred-looking skin (see a doctor)
Itching, burning or tenderness
Patches in beard, eyebrows or body hair
Nail pitting (can accompany alopecia areata)

Screen My PatchEach is treated very differently — and some need urgent care. This is a guide to discuss with a dermatologist, not a self-diagnosis tool.
Not sure which applies? The patch checker flags features that need prompt care.
Screen My PatchAlopecia areata is an autoimmune condition in which the immune system temporarily attacks hair follicles, producing smooth, round bald patches — usually without scaling or scarring. It can affect the scalp, beard, eyebrows or body, and is sometimes accompanied by subtle nail changes such as pitting.
Its course is unpredictable. In many people, especially with limited patches, hair regrows over months, sometimes on its own; in others it stays stable or recurs, and a minority develop more extensive loss. Because of this variability, treatment is chosen and led by a dermatologist to suit the extent of loss and the individual — it is not something to manage with shop-bought products, and outcomes vary.
It is also important to know that alopecia areata is not contagious and is not caused by poor hygiene. It can carry a real emotional impact, and support — both medical and psychological — is a valid part of care. A specialist can explain the realistic outlook and options for your situation.
Important: Treatments such as hair transplants, PRP or Finasteride are not standard first-line care for alopecia areata. Be cautious of anyone offering these as a quick fix for bald patches. Always start with a dermatologist's diagnosis.
Think it may be alopecia areata? A dermatologist can confirm and discuss suitable options.
See a DermatologistThese look different to a trained eye. The table is for understanding — only a dermatologist can confirm.
| Feature | Alopecia areata | Tinea capitis (fungal) | Traction alopecia | Scarring alopecia |
|---|---|---|---|---|
| Patch surface | Smooth, normal skin | Scaly, red, broken hairs | Thinning where pulled | Shiny, scarred |
| Onset | Sudden, round | Often with scaling/itch | Gradual, at tension points | Gradual, progressive |
| Contagious? | No | Yes | No | No |
| Permanent? | Usually not | Usually recovers if treated | Can be, if prolonged | Often permanent if late |
| Treatment | Dermatologist-led | Prescribed antifungals | Reduce tension early | Prompt specialist care |

Take Patch CheckerSee a DermatologistWith most hair concerns, a good routine helps. Patchy hair loss is different: the causes are largely medical conditions, and using the wrong approach can waste time or make things worse. A fungal infection treated with a cosmetic serum will keep spreading; a scarring alopecia left unassessed can cause permanent loss; and even alopecia areata is best managed with specialist-chosen options rather than guesswork.
That is why Hairsncares takes a diagnosis-first stance for patchy loss. An AI patch check can help you describe the patch and recognise urgency, but its job is to guide you to the right care, not to replace it. Any products we suggest here are gentle, supportive or cosmetic — for comfort and confidence alongside medical treatment, never instead of it.
Ready for a clear answer? A dermatologist can diagnose the patch and start the right plan.
Consult a DermatologistPatchy hair loss should always be assessed. Seek prompt dermatologist care — and treat the following as priority reasons to go quickly rather than buy products.

These products are non-medicated and intended for gentle scalp comfort and cosmetic support only. They do not treat, manage or cure alopecia areata, fungal infections, scarring alopecia or any other cause of patchy hair loss, and no product is guaranteed to regrow hair. Patchy hair loss requires a dermatologist's diagnosis; medical conditions such as tinea capitis and scarring alopecia need prescribed, doctor-led treatment. If a patch is scaly, inflamed, scarred, spreading, painful, or affects a child, seek prompt dermatologist care rather than relying on products. Results vary.
Before anything else, get the patch diagnosed so it is treated correctly.

Ask a DermatologistAll Ingredients"When a patch of hair disappears, the single most important thing is the diagnosis. Is it alopecia areata, where the skin is smooth and hair may regrow? Is it a fungal infection, which is contagious and needs antifungals — common in children? Or is it a scarring alopecia, where every week of delay can mean permanent loss? These look different to a trained eye, and they are treated in completely different ways. Please don't reach for a serum off a shelf for a bald patch — come and let us look, and we will guide the right care."

Hair loss treatment should start by identifying the pattern. Pattern thinning, diffuse shedding, patchy loss, sudden shedding and hair breakage need different next steps.
May suggest androgenetic alopecia or DHT-related pattern hair loss. Often gradual and progressive.
Androgenetic Alopecia →May relate to telogen effluvium, deficiency, thyroid, illness, stress, postpartum phase or diffuse pattern loss.
Diffuse Hair Thinning →Often follows a trigger weeks to months earlier, but sudden shedding should not be dismissed if severe or persistent.
Sudden Hair Fall →Persistent shedding needs cause-finding: chronic TE, thyroid, deficiency, medicines, hormones or pattern loss.
Chronic Hair Fall →Patchy loss may be alopecia areata, fungal infection or scarring alopecia and should be dermatologist-led.
Patchy Hair Loss →Breakage is shaft damage, not root shedding. It needs damage repair and styling changes, not root-hair-fall treatment.
Breakage vs Hair Fall →Cause Map
DHT-related follicle miniaturisation causing gradual pattern thinning in men and women.
Read Guide →Diffuse shedding after triggers such as fever, COVID, stress, childbirth, surgery, dieting or deficiency.
Read Guide →Iron, vitamin D, thyroid and nutritional issues can contribute to diffuse shedding and chronic hair fall.
Supplement Safety →Round bald patches need dermatologist diagnosis because causes and treatments differ greatly.
Patchy Hair Loss →Stress, rapid weight loss, illness, smoking and alcohol may contribute, but rarely act alone.
Stress Hair Loss →Breakage from heat, chemicals, friction or styling is different from root hair fall.
Breakage vs Hair Fall →Red Flags
Short-term shedding after a known trigger can be tracked with photos, routine consistency and symptom notes.
Use the AI Hair Test to organise pattern, duration, triggers, scalp symptoms and next-step direction.
Hair fall lasting more than 6 months, worsening crown thinning, a widening parting or unclear shedding needs evaluation.
Patchy loss, scalp pain, pus, crusting, bleeding, scarring-looking skin, sudden severe shedding or child scalp scaling needs prompt medical review.
Progression
Patches may appear suddenly, may improve, recur or progress — a dermatologist monitors and adjusts the plan.
Tinea capitis needs proper antifungal treatment; without it the infection spreads.
Scarring alopecias cause irreversible loss where delayed — prompt assessment prevents spread.
Early removal of tension can allow recovery; prolonged pulling can lead to permanent loss.
Diagnosis First
Patchy hair loss may be alopecia areata, a fungal infection (tinea capitis), traction, scarring alopecia or inflammation. These need different treatments, so product shopping should not replace a dermatologist's diagnosis — some scarring causes need prompt care to limit permanent loss.
