Hair loss after covid and other infections

Many people experience heavy hair loss a couple of months after covid or another febrile illness. It is a form of telogen effluvium — almost always temporary.

Common symptoms
  • Diffuse loss across the whole head
  • Large clumps of hair in the brush and shower
  • Onset 2-3 months after the infection
  • No bald patches
Common causes
  • Fever and infection (incl. covid-19)
  • Physical stress during illness
  • Sometimes a concurrent nutritional deficiency
Treatment options
  • Time — the hair usually recovers
  • Optimised nutrition
  • PRP as support
  • Blood tests if it drags on
Since the pandemic we have seen many people seek help for heavy hair loss after covid-19 — but the phenomenon is not unique to covid. Any febrile illness and infection that stresses the body can trigger the same reaction: telogen effluvium, where a large proportion of follicles enter the resting phase at the same time. The typical thing is that the shedding does not come during the illness itself, but two to three months afterwards. It can then come suddenly and feel dramatic — large clumps in the brush and a diffuse thinning across the whole head. Many become worried and think they have developed permanent hair loss. That is almost never the case. Because the follicles are not damaged, just temporarily dormant, the hair recovers on its own in the vast majority of cases within 6–12 months. What you can do yourself is ensure good nutrition (especially iron and protein), sleep properly and be patient — hair grows slowly, so the improvement shows with a delay. If the shedding drags on beyond a year, or if you see a clear pattern (recession, crown) rather than diffuse loss, there may be another underlying cause worth investigating with blood tests. At Hair TP Clinic we do a trichoscope assessment at a free consultation and can use PRP as support to stimulate the follicles during recovery.

Frequently asked questions

Questions about hair loss after covid and other infections

Is hair loss after covid permanent?

Almost never. It is telogen effluvium — the follicles are temporarily dormant, not damaged. The hair recovers on its own in most cases within 6–12 months.

Why did the hair loss come several months after I recovered?

That is typical of telogen effluvium. The follicles enter the resting phase during the strain and only shed 2–3 months later, which is why the loss often comes when you already feel recovered.

What can I do to help the hair come back?

Ensure good nutrition (iron, protein), sleep properly and be patient. PRP can be used as support. If it drags on beyond a year, another cause should be investigated with blood tests.
