Hypertrichosis or “Werewolf Syndrome”

What is Hypertrichosis


Hypertrichosis is never the result of chemotherapy. Hypertrichosis, also known as "werewolf syndrome" or "excessive hair growth," is a medical condition characterized by abnormal and excessive hair growth on areas of the body where hair does not typically grow or where it is not expected to be as prominent.

Hypertrichosis can be either congenital (present from birth) or acquired (develops later in life). It may affect small localized areas or involve larger regions of the body. The condition can be genetic or arise due to underlying medical conditions, hormonal imbalances, medications, or certain syndromes.

Chemotherapy, on the other hand, is a cancer treatment that uses drugs to destroy or inhibit the growth of rapidly dividing cancer cells. While chemotherapy can cause hair loss (alopecia) as a side effect, it is not associated with hypertrichosis. In fact, chemotherapy-induced alopecia leads to temporary hair loss rather than excessive hair growth.

In summary, hypertrichosis is not caused by chemotherapy, and its underlying causes are diverse, often involving genetic factors or other medical conditions unrelated to cancer treatment.
