What Is Hypertrichosis or Werewolf Syndrome? | Cosmetology


Overview of werewolf syndrome

Hypertrichosis, otherwise called werewolf disorder, is a condition portrayed by unnecessary hair development anyplace on an individual’s body. It can affect both women and men, but it is extremely rare. Abnormal hair growth may cover the face and body or occur in small spots. Hypertrichosis can show up upon entering the world or create after some time.

Read on to learn about the different types of hypertrichosis, what they may cause, and how to treat them.


There are several types of hypertrichosis:

  • Congenital villi hypertrichosis: It first appears in the form of natural villi, which is the fine hair present on the child at birth. But instead of disappearing over the subsequent weeks, fine, fine hair continues to grow in different places on the baby’s body.
  • Congenital hypertrichosis: abnormal hair growth that begins at birth and continues throughout a person’s life. Hair, usually long and thick, covers a person’s face and body.
  • Involuntary hypertrichosis: excessive hair growth of any type that appears in a specific area. In a couple of cases, more than one fix of hair is available.
  • Hirsutism: This type of hypertrichosis is restricted to women. It results in thick, dark hair that grows in places where there is no hair in women normally, such as the face, chest, and back.
  • Acquired hypertrichosis: unlike congenital hypertrichosis, the acquired form of the disease tends to develop later in life. Plus, it results in two types of non-fluffy hair: fluffy or final hair. Excess hair may grow in small spots or all areas of hair growth on a person’s body.

What causes hypertrichosis?

The cause of hypertrichosis is unknown. Congenital hypertrichosis is believed to be a hereditary issue that is acquired or brought about by unconstrained transformation. Acquired hypertrichosis sometimes occurs in people who are diagnosed at a later stage with cancer of some kind. This hair growth, also known as downward malignancy, is often restricted to the face with long fine, fine hair that can be seen on the nose and eyelids, which are the sites that are usually hairless. It is not known why cancer causes excessive hair growth.

It may be associated with acquired generalized hypertrichosis:

  • Late cutaneous porphyria
  • Poor nutrition, such as anorexia nervosa
  • Malignancy
  • Drugs, such as cyclosporine, phenytoin, androgenic steroids, minoxidil.

May be associated with acquired localized hypertrichosis:

  • Increase blood vessels
  • Frequent rubbing or scratching (minor lichen)
  • Gypsum application (temporary)
  • Frequent use of minoxidil, a strong topical steroid, iodine, psoralen (topical PUVA)
  • Trichomonas enlargement (long eyelashes) can arise from topical bimatoprost or systemic erlotinib.

Symptoms of hypertrichosis

The primary symptom of hypertrichosis is the presence of hair in greater amounts than normal for a person’s age, race, and gender. Hair may also appear in unusual areas. Not all hair caused by hypertrichosis is the same. Hypertrichosis can lead to the formation of three different types of hair:


Lanugo’s hair is long, thin, and extremely soft. It is similar to a newborn baby’s body hair. Lanugo’s hair will not usually have dye and will usually fall out a few weeks after birth. In individuals with hypertrichosis, this lanugo hair will stay until it is dealt with.


Fluffy hair is usually short, smooth, and faded. These hairs may show up everywhere on the body besides in territories where there are no hair follicles, for example, the mucous layers, the bottoms of the feet, and the palms of the hands.


Terminal hair is the darkest of the three hair types. The end hair is usually thick, coarse, and long. It is often related to hormones and is commonly found on the face, armpits, and groin. Women with hirsutism often have hairy ends on their face, back, arms, and chest. The seriousness of hypertrichosis manifestations may increment or decline with age.


Hypertrichosis is analyzed clinically by the event of an overabundance of hair than would be normal for age, sex, and nationality in regions unfeeling toward androgenic. The excess can be in the form of excessive length or density and may consist of any hair type (fluff, fluff, or tip).

Hypertrichosis treatment

There is no cure, but knowing whether it is congenital or acquired can help doctors choose a treatment. 3 If the abnormal hair growth is caused by another condition such as PCOS or thyroid disease, treatment of the primary medical disorder is the first treatment.

If the cause of hypertrichosis is a drug, dose adjustment or drug discontinuation may be sufficient to resolve hair growth. It may also be possible to give the person medication to prevent or slow hair growth. Topical medications called depilatory creams may also be prescribed For people with hirsutism, hormonal medications may be effective.

People with severe hypertrichosis may find it difficult, cumbersome, costly, and painful to have abnormal hair growth that is routinely plucked, shaved, bleached, or waxed. Even for people who do not have abnormal hair growth, these procedures are only temporary. It usually lasts a few weeks at most.

Laser hair removal is a long-term option but it usually requires more than one session, can be expensive, and may not work well on certain types of hair. Electrolysis is the FDA affirmed treatment for perpetual hair evacuation. While the method removes hair permanently, electrical treatments can be painful and expensive.

People with diffuse hypertrichosis may need to use more than one method of hair removal and may need to use it more frequently for the treatment to be effective. Hair from one area of the body may not be removed well – or safely – with certain methods. Certain areas of the body may also be very sensitive to some methods or more likely to be affected.

Because there are very few diagnosed cases, research on treatments for severe forms of this condition is limited. People with hirsutism and milder forms can find a method of hair removal that suits their needs and preferences, although it may take some trial and error.


Depending on the type, it is often accompanied by other symptoms and may be related to an underlying condition. There may be a genetic component to some forms of hypertrichosis, so anyone with a family history of this condition may want to talk to a doctor. Managing symptoms or treating the underlying cause is the only necessary and readily available treatment for hypertrichosis.
