Telogen effluvium (temporary diffuse hair loss)

A temporary, diffuse hair loss where many follicles enter the resting phase at once — often after stress, illness, childbirth or weight loss.

Common symptoms
  • Diffuse hair loss across the whole head
  • Lots of hair in the brush/shower
  • Onset 2-3 months after the trigger
Common causes
  • Severe stress
  • Fever, illness or surgery
  • Childbirth
  • Rapid weight loss / nutritional deficiency
  • Certain medications
Treatment options
  • Address the underlying cause
  • Optimised nutrition
  • Time — usually recovers
  • PRP as support
Telogen effluvium is one of the most common forms of temporary hair loss. It means that an unusually large proportion of the follicles enter the resting phase (telogen) at the same time and shed a few months later. The result is a diffuse loss across the whole head — not a defined patch — and often noticeably more hair in the brush and shower. The typical sign is that the shedding comes 2–3 months after a triggering event. Common triggers are severe physical or psychological stress, fever and infection, surgery, childbirth, rapid weight loss, nutritional deficiency or starting/stopping certain medications. The good news: telogen effluvium is almost always temporary. The follicles are not damaged but temporarily dormant. When the underlying cause is addressed — the stress settles, nutrition is restored, the body heals — the hair usually returns to normal growth within 6–12 months. Treatment is therefore mainly about identifying and addressing the cause, ensuring good nutrition and having patience. PRP treatment can be used as support to stimulate the follicles during recovery. A hair transplant, on the other hand, is not relevant, since the hair comes back on its own. At a consultation we help you distinguish telogen effluvium from hereditary hair loss.

Frequently asked questions

Questions about telogen effluvium (temporary diffuse hair loss)

How long does telogen effluvium last?

Usually 3–6 months of active shedding, followed by regrowth. Once the triggering cause has been addressed, the hair normally returns to normal within 6–12 months.

Do I need a transplant?

No. With telogen effluvium the follicles are alive and the hair comes back on its own. The focus is on addressing the cause; PRP can be used as support during recovery.

How do I know it is telogen effluvium and not hereditary?

Telogen effluvium causes diffuse loss across the whole head and often comes after a clear event. Hereditary hair loss follows a pattern (recession, crown). A trichoscope assessment gives the answer.
