Hypertrichosis: Exploring the "Werewolf Syndrome"

What is Hypertrichosis?

Hypertrichosis is a medical condition that causes excessive hair growth on the body, including the face. While it is sometimes referred to as “werewolf syndrome,” this is a misleading and stigmatizing term. Hypertrichosis is a real medical condition that affects real people, and using terms like “werewolf syndrome” can be hurtful and discriminatory.

The term “werewolf syndrome” likely originated from historical accounts of individuals with hypertrichosis being treated as freaks or monsters. However, it is important to recognize that hypertrichosis is a medical condition that requires compassionate and respectful treatment, just like any other medical condition.

It is important to use accurate and respectful language when referring to medical conditions like hypertrichosis to reduce stigma and discrimination.

Types of Hypertrichosis

There are two main types of hypertrichosis:

  1. Congenital Hypertrichosis: This type is present at birth and is often caused by genetic mutations inherited from parents.

  2. Acquired Hypertrichosis: Acquired hypertrichosis develops later in life due to various factors, including medical conditions, medications, hormonal imbalances, or certain cancers.

Causes of Hypertrichosis

The exact mechanisms that cause hypertrichosis are complex and not fully understood. In congenital hypertrichosis, genetic mutations play a significant role. Acquired hypertrichosis can be triggered by factors such as:

  • Medications: Some medications, particularly those used for cancer treatment or to treat other medical conditions, can cause excessive hair growth as a side effect.

  • Hormonal Imbalances: Hormonal imbalances, such as an increase in androgen hormones, can lead to excessive hair growth.

  • Underlying Medical Conditions: Certain medical conditions, including certain tumors or metabolic disorders, can trigger hypertrichosis.

Psychological and Social Impact

Hypertrichosis can have a profound impact on an individual’s self-esteem and mental well-being. The noticeable physical appearance can lead to social isolation, teasing, and emotional distress. Individuals with hypertrichosis often struggle to find acceptance and understanding from others.

Management and Treatment

Managing hypertrichosis involves addressing the underlying cause, if possible, and providing supportive care for affected individuals:

  • Hair Removal: Various hair removal methods, such as shaving, waxing, threading, and laser therapy, can help manage excessive hair growth.

  • Psychological Support: Mental health support and counseling can help individuals cope with the emotional challenges of living with hypertrichosis.


Hypertrichosis, often referred to as “Werewolf Syndrome,” is a rare genetic disorder that results in excessive and abnormal hair growth. While it is not physically harmful, the psychological and emotional impact of the condition can be significant. Understanding and raising awareness about hypertrichosis is essential to fostering empathy and creating a more inclusive society.
