Can alopecia areata go away on its own?

Finding a smooth, round bald patch is alarming. If it turns out to be alopecia areata, one of the first questions people ask is whether it will go away on its own. The honest answer is: often it does, sometimes it does not, and no one can predict it with certainty for any one person.

What alopecia areata is

Alopecia areata is a condition in which the immune system attacks hair follicles, causing hair to fall out, usually in small round patches on the scalp or face ¹. The follicles are not destroyed, which is why hair can come back. Researchers believe genetic and environmental factors both play a role ¹. DermNet estimates the lifetime risk at about 2%, and it affects people of all skin and hair colours ². For the basics, see our alopecia areata guide.

Can it go away without treatment?

Yes, in many people. The US National Institutes of Health notes that in most cases the hair grows back, though there may be later episodes of hair loss ¹. The American Academy of Dermatology says that for one or two bald spots present for less than a year, a dermatologist may suggest a wait-and-see approach, because many people, especially children, see hair return without treatment ³.

However:

• Growth back can be slow, and some people do not see the result they hoped for ³.
• New patches can appear while an older patch is filling in ¹.
• Relapse is common, and some people have several cycles of loss and growth over their lives ².
• Few people with extensive hair loss see their hair return without help ³.

What makes spontaneous recovery more likely?

According to NIAMS, hair tends to grow back on its own more fully in people with ¹:

• less extensive hair loss
• a later age of onset
• no nail changes
• no family history of the condition

DermNet lists factors linked with a less favourable outlook, including younger age at onset, more extensive disease, hair loss lasting more than a year, nail changes, the "ophiasis" pattern (a band of loss around the sides and back of the head), a family history, and the presence of eczema-type allergies or other autoimmune conditions ².

These are general patterns, not rules. Someone with "good" signs can still relapse, and someone with "poor" signs can still improve.

What happens when hair comes back

When hair returns, it may first grow in white or grey, then regain its natural colour over time ¹. This is normal and is not a sign that something has gone wrong.

Alopecia totalis and universalis

In a minority of people, alopecia areata progresses to loss of all scalp hair (alopecia totalis) or all body hair (alopecia universalis). DermNet puts the risk at about 5% to 10%, and recovery from these forms without treatment is unlikely ².

Should you wait or treat?

This is a decision to make with a doctor. Considerations include:

• Size and number of patches. For one or two small patches, waiting is a reasonable option ³.
• How long the patches have been there. Longer duration lowers the chance of spontaneous recovery ².
• Location. Patches on the eyebrows or beard may matter more to you than a hidden patch.
• Your feelings. If the hair loss is causing distress, treatment can be started even for small patches.

Treatment options include corticosteroid injections into patches, creams and lotions, and for extensive disease, contact immunotherapy or JAK inhibitor tablets ³. Treatment can help hair grow back faster, but response varies and hair loss may return when treatment stops ². No treatment changes the underlying tendency to the condition ¹.

While you wait

• Take photos every few weeks in the same light to see clearly whether patches are shrinking or spreading.
• Cover patches if you wish: hairstyles, hats, scarves, and for eyebrows, a brow pencil ².
• Be gentle with the scalp. There is no need to scrub or apply harsh products to the patches.
• Look after your wellbeing. Alopecia areata can affect mood and confidence. Support groups and counselling can help.
• Be cautious with products that promise fast results.

When to see a doctor

See a doctor if:

• you are not sure the patch is alopecia areata (other conditions, such as fungal infection, can look similar)
• patches are spreading or multiplying
• eyebrows, eyelashes or beard are affected
• a child has hair loss
• you notice nail pitting
• the hair loss is causing you distress

See what to do first when you notice hair loss and seeing a dermatologist.

Frequently asked questions

Will my alopecia areata patch grow back by itself?

Often, yes, especially small patches present for less than a year. But no one can promise this for any individual, and new patches can appear ^{1 3}.

Why is my new hair white?

Hair that grows back after alopecia areata may come in white or grey at first and usually regains its colour over time ¹.

How long should I wait before treatment?

There is no fixed rule. Discuss with a doctor; extensive loss or loss lasting longer than a year is less likely to recover on its own ^{2 3}.

Can alopecia areata come back after it clears?

Yes. Relapse is common, and some people have several episodes over their life ^{2 1}.
