A high fever or significant illness — including COVID-19 — is a classic trigger for telogen effluvium. The stress of the infection synchronises many follicles into their resting phase, and they shed together about 2-3 months later. It looks dramatic — handfuls in the shower, a thinner ponytail — and diffuse across the whole scalp rather than in a pattern. It is not the virus 'attacking' your follicles permanently.
The reassuring part: post-illness telogen effluvium recovers on its own, with density returning over 6-12 months once you've healed. Eating enough protein, checking ferritin and thyroid, and being gentle with styling help; minoxidil can support regrowth if you want to speed things along. If shedding hasn't settled by around a year, or you notice a receding hairline or crown thinning, check for pattern loss — illness can also unmask it.

FAQ
When does post-COVID hair loss stop?
Shedding usually peaks a few months after the illness and settles within 6-12 months, with density gradually returning. If it lasts beyond a year, see a dermatologist.
Is COVID hair loss permanent?
Almost never. It's temporary telogen effluvium triggered by the illness and fever, not permanent damage — the follicles recover once your body does.
