Men's Hair Loss: Causes, Treatment Options & What Works

Hair loss is a common concern for many men in New Zealand, affecting confidence, self-image, and sometimes even quality of life. While it’s often dismissed as a natural part of ageing, not all hair loss is the same, and in many cases, it’s treatable.

In this article, we’ll explain the most common hair loss causes, outline evidence-based treatment options, and help you determine when it’s time to seek medical advice. Whether you're noticing early thinning or experiencing more advanced hair loss, understanding the underlying reason is the first step toward managing it effectively.

What Causes Hair Loss in Men?

There are many different types of hair loss, and the causes range from genetic and hormonal to nutritional or stress-related. Here's a breakdown of the most common types in men:

1. Male Pattern Baldness (Androgenetic Alopecia)

This is by far the most common cause of hair loss in men. It affects approximately 50% of men over the age of 50, but can start much earlier—even in your 20s or 30s.

• Cause: Genetic sensitivity to dihydrotestosterone (DHT), a by-product of testosterone.

• Pattern: Receding hairline, thinning crown, or both.

• Progression: Usually slow and predictable.

Male pattern baldness is not caused by stress or poor circulation, despite popular myths. It's hereditary and hormonal in nature.

2. Telogen Effluvium (Stress-Related Hair Loss)

This form of temporary hair loss happens when a large number of hairs enter the resting (telogen) phase of the hair cycle all at once. It can be triggered by:

• Physical or emotional stress

• Illness or surgery

• Crash dieting or significant weight loss

• Certain medications

  
  

Hair tends to fall out evenly across the scalp. The good news? It often resolves on its own within 6–9 months once the underlying cause is addressed.

3. Alopecia Areata

An autoimmune condition where the body attacks its own hair follicles, leading to sudden bald patches. It can occur at any age and may be linked to other autoimmune conditions.

• May be temporary or long-term

• Sometimes responds to steroid treatment

This condition requires medical assessment and may be managed by a GP or dermatologist.

4. Other Causes

Other contributors to male hair loss include:

• Nutrient deficiencies (e.g. iron, zinc, vitamin D)

• Thyroid disorders

• Medications (chemotherapy, some blood pressure and antidepressant meds)

• Skin conditions (e.g. scalp infections or psoriasis)

If your hair loss is patchy, rapid, or accompanied by other symptoms (itching, scaling, pain), you should consult a healthcare provider.

What Treatment Options Actually Work?

When it comes to male hair loss treatment in NZ, there are a number of options available, ranging from over-the-counter remedies to prescription medications. Effectiveness varies based on the cause of the hair loss and how early you begin treatment.

1. Minoxidil (Topical Treatment)

• Available without a prescription in New Zealand

• Applied directly to the scalp (usually twice daily)

• Works by prolonging the growth phase of the hair cycle and improving blood flow to follicles

Best for: Male pattern baldness and telogen effluvium

Note: It can take 4–6 months to notice results, and continuous use is required to maintain growth.

2. Finasteride (Oral Medication)

• Prescription-only medication

• Works by blocking the enzyme that converts testosterone into DHT

• Slows or stops hair loss in many men, and may promote regrowth

  
  

Best for: Male pattern baldness

Considerations: Possible side effects include decreased libido or mood changes in some users. A GP consultation is required to assess suitability.

3. Combination Therapy

Some men benefit from using minoxidil and finasteride together, targeting both the hormonal and follicular aspects of hair loss.

Other treatment combinations may include:

• Nutritional support (e.g. iron, biotin)

• DHT-blocking shampoos (limited evidence)

4. Hair Transplant Surgery

While not available through Pocket Lab, some men explore hair transplant procedures. This involves relocating healthy follicles from the back of the head to balding areas.

Pros: Permanent results

Cons: Expensive, invasive, and may require multiple sessions

Surgery is typically considered only after trying less invasive treatments first.

When Should You See a Doctor?

It can be hard to know when to seek help, especially when hair loss is gradual. Consider booking a consultation if:

• You’re under 30 and noticing significant thinning

• Hair is falling out in clumps or patches

• You have other symptoms (e.g. scalp irritation, weight changes)

• You're feeling anxious or self-conscious about your hair loss

• You want to explore prescription options like finasteride
