Yes, COVID-19 can cause hair loss, and if you noticed unusual shedding a couple of months after being ill, you are far from alone. The good news is that in almost all cases it is a temporary type of shedding called telogen effluvium, triggered by the physical stress of the illness, and hair usually recovers on its own over several months. Here is why it happens, how long it lasts, and how to support your hair while it grows back.

Can COVID really cause hair loss?

It can. Beyond the well-known symptoms, many people notice a surge of hair shedding in the weeks and months after COVID-19. This is not the virus attacking your hair, it is your body's response to the stress of being ill. Any significant illness, especially one with a high fever, can do the same, which is why doctors saw the identical pattern after flu long before COVID existed.

Why does it happen? COVID and telogen effluvium

The mechanism has a name: telogen effluvium, sometimes called shock hair loss. Your hair grows in a cycle, with each strand spending years in the growth (anagen) phase before resting and shedding (the telogen phase). A major physiological stress, like a fever, infection or emotional distress, can push a large share of follicles into the resting phase early and all at once.

Those resting hairs then all shed together around 2 to 3 months later, which is why the hair loss often arrives well after you feel better, when the illness is the last thing on your mind. Instead of the normal 50 to 100 hairs a day, you might shed 300 or more, and it shows up as thinning all over rather than bald patches. You can read the full picture in our guide to what causes telogen effluvium.

How long does COVID hair loss last?

For most people the heavy shedding lasts around 3 to 6 months and then settles as the hair cycle resets. New regrowth follows, though because hair grows about a centimetre a month, it can take a further few months for your hair to feel back to its normal thickness, and you may notice short new "baby hairs" around your hairline as it recovers, which is a good sign.

When should you see a doctor?

Post-COVID shedding usually resolves on its own, but check in with your GP if:

• the shedding continues beyond six months,
• you see distinct bald patches rather than overall thinning (this suggests a different condition),
• it comes with other symptoms such as ongoing fatigue, weight changes or feeling generally unwell, or
• you simply want reassurance, a simple blood test can rule out other treatable causes like low iron or a thyroid issue.

How to support your hair after COVID

There is no product that treats telogen effluvium, time and recovery do that. But you can give the regrowth the best possible conditions:

1. Feed the recovery

Rebuilding hair is nutritionally demanding. Prioritise protein, iron, zinc and the B vitamins, exactly the things an illness tends to deplete.

GrowPro Hair Growth Gummies

Sugar-free vegan gummies with biotin and zinc, which contribute to the maintenance of normal hair, a convenient daily top-up alongside a balanced diet while your hair recovers. They support nutrition, they are not a treatment, and if you suspect a deficiency ask your GP for a blood test.

2. Be kind to the hair you have

While the cycle resets, reduce breakage so your hair looks as full as possible: go easy on heat styling, avoid tight ponytails, and use a gentle, sulphate-free wash routine.

Grow Me® Hair Growth Shampoo

A gentle, sulphate-free shampoo with biotin, caffeine, rosemary, niacinamide and argan oil. It cleanses without stripping and supports a comfortable scalp and the look of fuller, thicker-feeling hair while your regrowth comes through. Pair it with Condition Me conditioner to protect the lengths.

3. Look after your scalp

A comfortable, cared-for scalp is the best environment for new growth. A lightweight leave-on scalp serum, massaged in gently a few times a week, supports a healthy-looking scalp, and the massage itself is a pleasant ritual while you wait for regrowth.

4. Manage stress and rest

Since stress is itself a trigger for shedding, sleep, gentle exercise and downtime are genuinely part of the fix, for your hair as much as the rest of you.

Frequently asked questions

Does COVID cause permanent hair loss?

Almost never. Post-COVID shedding is nearly always telogen effluvium, which is temporary, and hair regrows once the body has recovered.

How soon after COVID does hair loss start?

Typically 2 to 3 months after the illness, because the affected hairs finish their resting phase before they shed.

How long does hair loss after COVID last?

Usually 3 to 6 months of increased shedding, followed by gradual regrowth over the months after that.

Can the COVID vaccine cause hair loss?

Significant shedding after vaccination is far less common than after the illness itself. If you are concerned about any shedding, your GP can help find the cause.

Will my hair grow back after COVID hair loss?

Yes, in the vast majority of cases. Supporting your nutrition and being gentle with your hair helps it along.

Should I see a doctor about post-COVID shedding?

See your GP if it lasts beyond six months, comes in patches, or arrives with other symptoms such as ongoing fatigue.

Do hair products cure COVID hair loss?

No product treats telogen effluvium. Gentle, supportive products help your hair look its best while it recovers naturally.

Hair loss after COVID is unsettling, but it is one of the most predictable and temporary kinds there is: shed, settle, regrow. Look after your recovery, feed your body well, treat your hair gently, and give it time. For more, read our full guide to telogen effluvium or explore why hair thins and how to support it.
