Quick Summary: Anagen effluvium is a rapid form of hair loss that occurs during the active growth phase, often as a result of chemotherapy or radiation. Unlike other types of shedding, it happens very quickly, but hair typically begins to regrow once the treatment is completed.
What is causing my rapid hair loss?
Anagen effluvium occurs when the hair follicles are suddenly interrupted during their active growth phase (the anagen phase). This is usually caused by medical treatments like chemotherapy or radiation, which target rapidly dividing cells. Because hair follicles are some of the fastest-growing cells in the body, they are often affected as a side effect.

Is this different from normal shedding?
Yes. While normal shedding (telogen effluvium) happens 3 months after a trigger, anagen effluvium happens much faster—usually within days to weeks of starting treatment. The hair shafts often appear tapered or broken because the growth was stopped mid-cycle.
Taking Charge: Managing your health during treatment
- Scalp Cooling:If undergoing chemotherapy, talk to your oncology team about “cold caps,” which can reduce the amount of medication that reaches the hair follicles.
- Gentle Care:Use a soft-bristled brush and a mild, fragrance-free shampoo. Avoid heat styling and chemical treatments.
- Silk or Satin:Sleeping on a silk or satin pillowcase can reduce friction and tugging on fragile hair.
- Head Coverings:Soft scarves, hats, or comfortable wigs can protect the sensitive scalp from sun and cold.
When should I see a doctor?
You should work closely with your oncology team and a dermatology provider if:
- The hair loss is accompanied by significant scalp sensitivity or pain.
- You notice signs of infection, such as pus, extreme redness, or swelling on the scalp.
- Your hair does not begin to show signs of regrowth 3 to 6 months after completing treatment.
- You wish to discuss medical options for stimulating regrowth after treatment.
