TL;DR: Hair loss has many causes from genetics to stress and affects both men and women. Proven treatments such as minoxidil and finasteride can slow hair loss, while modern therapies like PRP and laser treatments support hair regrowth. In advanced cases, a FUE hair transplant offers a long-term solution. The German hair transplant clinic MediFUE combines medical expertise with personalized consultations and high-quality procedures ideal for anyone seeking a sustainable solution to hair loss.
Why hair loss occurs: the main causes
Hair loss usually develops due to a combination of genetic predisposition and hormonal influences, particularly the hormone DHT, which causes hair follicles to shrink. Other causes include nutrient deficiencies, chronic stress, thyroid disorders, as well as external factors such as excessive styling or aggressive hair-care products. An accurate diagnosis is essential to choose the right treatment.
Genetics & hormonal influences (DHT)
The most common cause of permanent hair loss is hereditary hair loss (androgenetic alopecia). In this condition, hair follicles are sensitive to the hormone DHT (dihydrotestosterone), leading to progressive miniaturization especially at the temples, crown, and back of the head.
Lifestyle, nutrition & stress
Chronic stress, vitamin deficiencies (e.g., iron, zinc, biotin), smoking, and an unhealthy diet can also cause diffuse hair loss. Lack of sleep and hormonal changes (for example after pregnancy) play a role as well.
Environment, styling & mechanical stress
Excessive styling, tight hairstyles, aggressive care products, or frequent straightening/dyeing put strain on the scalp. Over time, this can lead to hair damage and increased hair loss.
Proven medical treatments for hair loss
The two most thoroughly studied medications for hair loss are minoxidil (topical) and finasteride (oral). Minoxidil improves blood flow and prolongs the hair growth phase. Finasteride lowers DHT levels in the body and thereby slows the progression of genetic hair loss however, it is approved for men only. Both treatments require continuous use and work best in early stages.
Minoxidil (topical)
An over-the-counter treatment applied directly to the scalp. It extends the hair growth phase, improves scalp circulation, and can counteract hair loss. Effective for both men and women.
Finasteride (oral, prescription)
Targets the hormone DHT the main driver of genetic hair loss. Finasteride can stop progression or even stimulate new growth, but it is for men only and must be taken under medical supervision.
Modern non-surgical methods for hair regeneration
Non-surgical therapies such as PRP (platelet-rich plasma), low-level laser therapy (LLLT), or microneedling offer effective alternatives to surgery especially for early to moderate hair loss. They stimulate follicle regeneration, improve scalp circulation, and can reactivate hair growth. These methods are often gentle, low-risk, and work well in combination with medication.
PRP therapy (platelet-rich plasma)
PRP involves processing the patient’s own blood and injecting concentrated plasma into the scalp. The growth factors stimulate follicle regeneration and thickening. Particularly effective for diffuse or hormonally related hair loss.
Low-level laser therapy (LLLT)
Infrared light stimulates cellular activity and scalp circulation. This method is painless, safe, and can be used at home or in the clinic ideal as a supportive treatment alongside others.
Microneedling and scalp care
Microneedling creates tiny microchannels in the skin, allowing active ingredients to penetrate more effectively. Combined with serums or PRP, it can further stimulate hair growth.
Hair transplantation in Germany: when and for whom it makes sense
When medication or therapies are no longer sufficient, a hair transplant offers a permanent solution. It is often the best option for advanced hair loss (Norwood 3–6).
Suitable for:
- Men with stabilized hair loss
- Women with diffuse thinning in the crown area
- Individuals with sufficient donor hair at the back of the head
Not suitable when:
- Hair loss is still actively progressing
- Autoimmune conditions are present (e.g., alopecia areata)
- Expectations are unrealistic
The most common method today is the FUE technique (follicular unit extraction), where individual follicles are harvested and transplanted. This approach is minimally invasive, scar-free, and delivers natural-looking results.

Pros and cons of different treatment options
| Treatment | Pros | Cons |
| Minoxidil / Finasteride | Easy to use, effective when started early | Daily use required, possible side effects |
| PRP therapy | Natural, stimulates regeneration | Multiple sessions needed, not effective for everyone |
| LLLT / Microneedling | Non-invasive, suitable for home use | Long-term application required |
| Hair transplantation | Permanent, visible results | Higher cost, suitable only for stable hair loss |
How to choose the right treatment: a decision checklist
Before choosing a method, clarify the following questions:
- How advanced is my hair loss?
- Do I have a diagnosis from a specialist?
- Am I prepared for long-term treatment (e.g., medication)?
- Is a surgical procedure an option for me?
- What results do I realistically expect?
A consultation for example at MediFUE can help define the most suitable therapy on an individual basis.
Tips for prevention and maintaining scalp health
Even though genetic hair loss cannot always be fully prevented, there are effective measures to slow progression and maintain hair health:
- Healthy diet: Iron, zinc, biotin, and omega-3 fatty acids support hair growth.
- Reduce stress: Chronic stress can worsen hair loss yoga, exercise, or meditation can help.
- Gentle care: Avoid harsh shampoos, hot water, and frequent coloring.
- Scalp massage: Promotes circulation and may stimulate hair growth.
- Avoid smoking: Nicotine negatively affects scalp circulation.
