PLOTSELINGE HAARUITVAL

Sudden hair loss: possible causes and patterns

Wanneer haaruitval ineens opvalt, zijn verdeling en timing essentieel. Diffuse shedding, kale plekken en hoofdhuidveranderingen wijzen niet automatisch in dezelfde richting.

In brief

  • Plotselinge haaruitval kan diffuus of plaatselijk zijn.
  • Een lichamelijke, hormonale of emotionele trigger kan maanden eerder hebben plaatsgevonden.
  • Ronde kale plekken volgen een ander profiel dan diffuse shedding.
  • Snelle progressie en hoofdhuidklachten vragen om tijdige beoordeling.

QUICK CHANGE

What do we mean by sudden hair loss?

It involves a clear change that becomes noticeable within weeks or a few months. Sometimes you mainly notice more hairs coming loose; sometimes a specific area becomes visible.

The rate alone does not reveal the cause. The distribution and accompanying signs complete the picture.

View the different types of hair loss

ACROSS THE ENTIRE SCALP

Diffuse hair loss

With diffuse hair loss, more hairs shed across the scalp without one sharply defined area. This may be due to a temporary shift in the hair cycle.

Hair density may decrease somewhat everywhere, while the hairline usually does not change on its own.

LOCAL

Round or sharply defined bald patches

A smooth, round patch has a different pattern than diffuse hair loss. Alopecia areata is one possibility and can become visible relatively quickly.

Have localized bald patches assessed to determine the pattern and appropriate next steps.

POSSIBLE CONTEXT

Illness, stress, hormones and nutrition

Fever, an infection, surgery, severe stress, weight loss, or a hormonal change can affect the hair cycle. The visible hair loss often only occurs later.

A timeline of the preceding months helps identify possible connections.

When is prompt assessment important?

Seek medical evaluation for rapidly expanding bald patches, pain, redness, scaling, scar-like skin, or loss of eyebrows or eyelashes.

Severe, persistent diffuse hair loss or additional physical symptoms are also reasons to seek further evaluation.

Begin bij verdeling en snelheid

Noteer wanneer de verandering voor het eerst opviel, waar het haar dunner wordt en of er recent ziekte, stress, een operatie, gewichtsverlies of hormonale verandering was.

Vragen over plotselinge haaruitval

What causes sudden hair loss?

Possible causes include illness, fever, surgery, hormonal changes, severe stress, weight loss, nutritional deficiencies, and autoimmune processes.

Can shedding begin months after a trigger?

Yes. With telogen effluvium, there is often a delay between the change in the hair cycle and the point at which more hair starts to fall out.

What is the difference between diffuse hair loss and bald patches?

Diffuse hair loss is spread across the scalp. Bald patches are clearly localized and often follow a different pattern.

Can sudden outages decrease on their own?

With a temporary shift in the hair cycle, hair loss may gradually decrease once the situation has stabilized. The course varies from person to person.

Which signs require prompt assessment?

Rapidly expanding spots, pain, redness, scaling, scar-like skin, or other physical symptoms warrant timely evaluation.
