What is unwanted hair growth?

Unwanted hair growth refers to hair that grows in places or in amounts that are considered bothersome. This can include, for example, the face, chest, back, or other areas where visible hair growth is undesirable.

In women, the term "hirsutism" is used to describe increased hair growth in a male pattern. In both men and women, increased hair growth can also be caused by genetic factors or changes in hormone balance.

The condition can range from mild and primarily cosmetic to more severe and requiring treatment.

Causes of increased hair growth

There can be several causes of unwanted hair growth, and it is often a combination of factors.

Common causes include:

  • Hormonal changes (e.g., elevated levels of androgens)
  • Genetic conditions
  • Conditions such as polycystic ovary syndrome (PCOS)
  • Medicine
  • Menopause
  • Weight changes

In some cases, there is no specific medical explanation, and the hair growth is considered a normal variation.

Consultation with a dermatologist

If you are experiencing unwanted hair growth, it may be a good idea to consult a dermatologist.

During the consultation, the doctor will typically:

  • Assess the extent and pattern of hair growth
  • Review your medical history and any symptoms
  • Assess the need for hormonal testing
  • Talk to you about your wishes and expectations regarding treatment

A thorough assessment is essential for determining the most effective and appropriate treatment.

Treatment options

Treatment depends on the cause, the extent of hair growth, and your preferences. Often, several methods are combined to achieve the best results.

Medical treatment

  • Hormone therapy can reduce hair growth caused by hormonal imbalances
  • May be relevant in cases such as PCOS
  • Requires medical evaluation and follow-up

Laser treatment

  • Reduces hair growth by destroying the hair follicles
  • Most effective on dark hair
  • Requires multiple treatments
  • Often provides long-lasting results

IPL (Intense Pulsed Light)

  • Similar to a laser, but with wider light waves
  • Suitable for larger areas
  • Results may vary depending on skin and hair type

Temporary methods

  • Shaving
  • Waxing
  • Hair removal
  • Hair removal creams

These methods remove hair temporarily but do not affect hair growth itself.

When should you see a dermatologist?

It’s a good idea to see a doctor if hair growth occurs suddenly or increases rapidly, or if you’re also experiencing symptoms such as acne, hair loss, or menstrual irregularities. You should also consider seeking medical advice if the hair growth is affecting your quality of life or if you’re looking for a more permanent solution.

An early evaluation can be important for ruling out any underlying conditions and ensuring that you receive the appropriate treatment.
