Unwanted Hair Growth: Common Symptoms and Causes

March 30, 2026

Are you experiencing sudden or bothersome hair growth in places where you don't want it?

For many people, this can cause frustration or anxiety, but help is available. At Lægerne Danmark, we can help you understand why hair growth occurs and what options you have for managing it.

Symptoms to watch out for

Unwanted hair growth doesn't always appear in the same way. It can be thick, dark hair in places where you don't normally have hair, or finer hair that suddenly becomes more noticeable.

Other symptoms that often accompany this condition may include:

  • Sudden change in hair pattern
  • Hair that grows faster than usual
  • Clumps of hair in new areas
  • For women: changes in the menstrual cycle or skin problems such as acne

These symptoms can cause both physical and emotional distress. It’s perfectly normal to feel self-conscious or uncomfortable, and that’s a good reason to talk to a dermatologist, who can determine the cause.

Hormonal changes can affect hair growth

Hormones play a major role in hair growth. For women, an excess of androgens (male hormones) is a common cause of hair growth on the chin, upper lip, chest, or stomach.

Hormonal changes can occur during puberty, pregnancy, menopause, or due to conditions such as polycystic ovary syndrome (PCOS). In men, imbalances in testosterone or other hormones can affect hair patterns, but this is less common.

Polycystic ovary syndrome (PCOS)

PCOS is a common condition in which women may experience unwanted hair growth, irregular periods, acne, and weight fluctuations. Early evaluation by a doctor can help manage these symptoms, and there are effective treatment options available that both regulate hormones and reduce hair growth.

At Lægerne Danmark, we can assist with hormone testing, blood tests, and personalized treatment plans to ensure you receive the right solution for you.

Medications and Side Effects

Certain types of medication can affect hair growth. Steroids, some hormone medications, anti-epileptic drugs, and blood pressure medications can lead to increased hair growth.

If you notice a sudden change in hair growth after starting a new medication, it is important to talk to your doctor. Sometimes adjusting the medication can alleviate the problem, while in other cases a different approach is needed.

Genetics and hereditary factors

Family history can play a significant role. If women in your family have experienced increased hair growth, it may be genetic. This type of hair growth is often uniform and develops gradually.

Knowing your family history can be helpful when your doctor is determining the cause. However, this does not mean that genetic hair growth cannot be managed; there are both medical and cosmetic solutions available that can reduce its visibility and bring peace of mind to your daily life.

The Role of Lifestyle

Your lifestyle can affect your hormonal balance and, consequently, hair growth. Being overweight, insulin resistance, stress, and rapid weight fluctuations can increase the risk of unwanted hair growth in both men and women.

Small changes in your daily routine can make a difference: regular exercise, a balanced diet, and stress reduction can help stabilize your hormones and improve your overall well-being. However, lifestyle changes alone will rarely eliminate hair growth caused by genetic or hormonal factors.

When should you see a dermatologist?

It can be difficult to determine whether hair growth is normal or requires medical attention. In general, you should contact a dermatologist if:

  • Hair growth occurs suddenly or in patches
  • It is accompanied by other symptoms such as menstrual irregularities, acne, or weight changes
  • You are experiencing emotional distress or low self-esteem

At Lægerne Danmark, you can get a quick assessment and personalized advice, often with the option of same-day, evening, or weekend appointments. We focus on solutions that work for you and your daily life.

Treatment options

How to manage hair growth depends on the cause. If hormonal imbalances are the cause, medication can be effective. For many people, cosmetic solutions such as laser treatment, waxing, epilators, or medical hair removal creams are a practical option.

The most important thing is that the treatment is chosen based on a doctor’s assessment. That way, you’ll get a solution that is both safe and effective, and that suits your preferences and needs.

Cosmetic and practical solutions

Laser treatment reduces hair growth over time and may be ideal if you’re looking for a more permanent solution. Waxing and epilators provide quick results but require repeated use, while medicated creams can help slow hair growth in small areas.

A dermatologist can help determine which treatments are best for you and which ones can be combined to achieve the best results.
