Anagen effluvium explained
Anagen effluvium causes rapid loss of hairs that were actively growing. It can follow intense injury to the follicle, certain medical treatments or diseases and needs to be placed in context.
Dermatology care
Hair loss deserves diagnosis, not random trial and error
Unlike telogen effluvium, shedding may begin soon after the trigger. Recovery depends on the cause, severity and whether the follicles remain viable.
- The evaluation reviews medicines, procedures, recent illnesses and the timing of loss. Trichoscopy and additional tests help when the presentation is not typical.
- A clear care plan with follow-up of symptoms and density.
- Care for patients in São Mateus and the Northern Espírito Santo region.

Possible presentation
Signs that deserve attention
What may be involved
Chemotherapy is a known cause, but other exposures and illnesses can affect the hair matrix. Do not stop medical treatment without guidance.
Appearance alone cannot confirm the type of alopecia. Pattern, timing and symptoms change the investigation.
Evaluation
How diagnosis is built
1
Medical history
Onset, speed, triggers, illness, medicines, styling habits and family history are reviewed.
2
Examination and trichoscopy
The evaluation reviews medicines, procedures, recent illnesses and the timing of loss. Trichoscopy and additional tests help when the presentation is not typical.
3
Individual plan
The type and activity of alopecia, together with general health, determine whether tests, biopsy, treatment or monitoring are appropriate.
Care
Treatment depends on the cause
The priority is to control the cause with the responsible medical team and protect the scalp. Regrowth may follow removal of the trigger, but timing and texture vary.
Address the origin
Correct or control an identifiable trigger whenever possible.
Protect follicles
Reduce inflammation, traction or progression to protect viable follicles.
Follow progress
Compare symptoms, photographs and density over time without promising the same result for everyone.
When to seek an earlier assessment
Abrupt unexplained loss, wounds, pain, marked scale, systemic symptoms or occupational exposure warrant prompt assessment.
FAQ · common questions
Questions about anagen effluvium
01Is anagen effluvium the same as telogen effluvium?
No. Anagen effluvium usually causes faster loss from injury to growing hairs; telogen effluvium appears later after a trigger.
02Does chemotherapy always cause total hair loss?
Not necessarily. The pattern depends on the medicine, dose and individual sensitivity.
03Will the hair grow back?
Many people regrow hair after the cause is controlled, but timing and texture vary.
04Should I stop the suspected medicine?
No. Speak with the prescribing doctor; stopping treatment on your own can be dangerous.
05How should I care for the scalp?
Use gentle cleansing and protect the skin from sun and friction, following the treating team’s guidance.
