Anagen Effluvium

Anagen effluvium is widespread hair loss that can affect your scalp, face and body.

One of the most common causes of this type of hair loss is the cancer treatment chemotherapy. In some cases, other cancer treatments – including immunotherapy and radiotherapy – may also cause hair loss.

The hair loss is usually noticeable within a few weeks of starting treatment. However, not all chemotherapy drugs cause hair loss and sometimes the hair loss is so small it's hardly noticeable.

It may be possible to reduce hair loss from chemotherapy by wearing a special cap that keeps the scalp cool. However, scalp cooling is not always effective and not widely available.

In most cases, hair loss in anagen effluvium is temporary. Your hair should start to grow back a few months after chemotherapy has stopped.
