DUUR EN HERSTEL VAN DIFFUSE HAARUITVAL

How long does telogen effluvium last?

Bij telogeen effluvium begint de zichtbare haaruitval meestal twee tot vier maanden na een trigger. De uitval neemt vaak binnen drie tot zes maanden af, maar het herstel van het oorspronkelijke haarvolume duurt doorgaans langer.

Tijdlijn van diffuse haaruitval en geleidelijk herstel bij telogeen effluvium

In brief

De haaruitval begint meestal twee tot vier maanden na de uitlokkende gebeurtenis.
De actieve periode van overmatige haaruitval duurt bij acuut telogeen effluvium vaak drie tot zes maanden.
Nieuwe haren kunnen al groeien terwijl je nog steeds meer oude rustharen verliest.
Zichtbaar herstel van dichtheid en lengte kan zes tot twaalf maanden of langer duren.
Haaruitval die langer dan zes maanden aanhoudt wordt chronisch genoemd en verdient herbeoordeling.

AFTER THE TRIGGER

Why does hair loss only start later?

A trigger moves more hairs into the resting phase at once, but these hairs do not fall out immediately. They initially remain in the hair follicles.

That is why increased shedding usually becomes noticeable only two to four months after an illness, childbirth, surgery, severe stress, or another trigger. This delay can make it difficult to link the cause to the hair loss.

THE ELIMINATION PHASE

How long will the hair continue to shed excessively?

With acute telogen effluvium, excessive shedding often gradually decreases within three to six months, provided the trigger has passed or the underlying cause has been addressed. The course is not the same every week.

Some days or hair washes may seem worse than others. Therefore, look at the overall trend over several weeks and months, rather than an exact daily hair count.

NEW HAIR GROWTH

When does regrowth become visible?

New hairs may already begin growing while resting hairs are still being shed. Short new hairs along the hairline or parting may be a sign of recovery.

Because scalp hair grows slowly, it takes time for new hairs to add length and visible volume. Early regrowth therefore does not mean that density has been restored immediately.

VOLUME RESTORATION

When will the hair feel fuller again?

The original volume generally returns later than the hair loss stops. For many people, visible regrowth takes six to twelve months; with long hair, it can take even longer before the new hairs catch up with the existing length.

Recovery varies from person to person and may be slower when the trigger persists, deficiencies have not been corrected, or androgenetic alopecia is also present.

IF IT TAKES LONGER

When is reassessment advisable?

Telogen effluvium is called chronic when increased shedding persists for more than six months. This does not automatically mean permanent baldness, but it does mean that possible triggers and other forms of hair loss should be reassessed.

Have the situation evaluated if shedding persists or increases, there is visible pattern thinning, bald patches, scalp symptoms, or other physical symptoms. Sometimes an examination of the scalp, medical history, and blood work is necessary.

Haaruitval en herstel overlappen

Dat je nog haren verliest, betekent niet automatisch dat er geen herstel plaatsvindt. Nieuwe groei kan rustende haren uit het haarzakje duwen. Kijk daarom naar het verloop over meerdere maanden en niet naar één wasbeurt of één foto.

Vragen over de duur van telogeen effluvium

With acute telogen effluvium, excessive shedding often decreases within three to six months. Restoring density and length usually takes longer.

Yes. New growth can push resting hairs out of the hair follicle. As a result, shedding and regrowth may temporarily occur at the same time.

Visible regrowth can take six to twelve months or longer. The time required depends, among other things, on hair length, severity, trigger, and any other causes.

When increased hair loss persists for longer than six months, it is referred to as chronic telogen effluvium. Reassessing triggers and the diagnosis is advisable.

Yes. A new or recurring trigger can cause another episode. An uncorrected underlying cause can also prolong the course.

Have hair loss assessed if it does not decrease after six months, clearly worsens, follows a pattern, or is accompanied by bald patches, scalp problems, or other symptoms.
