We usually distinguish between two common types of hair loss:
Sudden hair loss (medically called “effluvium”): Hair thins all over, with even and sudden shedding across the entire scalp.
Common triggers include stress, infections, medications, hormonal changes (e.g., pregnancy), or nutrient deficiency.
This type is usually temporary.
Genetic hair loss (medically called “androgenetic alopecia”): Hair gradually thins in certain patterns over months or years.
It’s caused by a hereditary predisposition, where hair roots react sensitively to certain hormones.
We recommend evaluation if you …
- suddenly experience noticeable hair shedding, for example while showering, brushing or noticing it on your pillow
- notice your hair thinning overall or losing its fullness
- see bare or thinning spots on the crown or parting (common with genetic hair loss)
- are bothered by receding hairline or thinning temples
- notice hair loss after an infection, childbirth or hormonal change
- wonder if your hair loss is temporary or caused by an inherited condition

What happens during an evaluation for sudden or genetic hair loss?
We begin with a scalp examination. If needed, we add a hair and root analysis or a blood test. A blood test helps determine whether nutrient deficiencies or hormone imbalances could be affecting your hair.
What treatment options are available for hair loss?
For sudden-onset hair loss (effluvium), we focus on the following:
If test results show missing nutrients or hormonal imbalance, we may recommend supplements or hormonal support in cooperation with your general practitioner or gynecologist.
If the hair loss is stress-related, sometimes rest and relief are already helpful. For genetic hair loss (androgenetic alopecia), topical solutions that are applied to the scalp are often used.
Certain medications—for example in tablet form—can also be appropriate, provided there are no medical reasons against it.
We’ll decide together which treatment best suits you, and we’ll guide you step by step. Platelet-Rich Plasma (autologous blood treatment) can be helpful in both cases:
Here, components of your own blood are injected into the scalp.
Important: Not all hair loss requires immediate treatment. Sometimes it’s enough to know there’s no serious cause.
We support you with an honest assessment, modern methods, and plenty of experience with all types of hair loss.

FAQ – Common Questions About Hair Loss
What’s the difference between sudden hair loss and genetic hair loss?
Sudden hair loss (effluvium) affects the entire scalp evenly, for example after stress, infections, or hormonal changes. Genetic hair loss (androgenetic alopecia) progresses slowly and often starts at the part, crown, or temples.
How can I tell which type of hair loss I have?
Sudden hair loss often shows up as more hair on your pillow, in your brush, or during washing. Genetic hair loss tends to appear as thinning at the part or a receding hairline. A dermatological evaluation provides clarity.
What causes sudden, increased hair loss?
Physical or emotional stress, infections with fever, surgeries, iron deficiency, hormonal changes, or medications. The hair loss often begins 2–3 months after the trigger.
What role does stress play in hair loss?
Stress is one of the most common triggers for sudden hair loss. It can disrupt the hair cycle and lead to shedding, even if there’s no physical illness. Reducing stress is key in such cases.
What is androgenetic alopecia?
This is the medical term for hereditary hair loss. The hair roots are sensitive to the hormone DHT, which shortens the growth phase. It usually shows up as thinning hair on the crown or a receding hairline.
Is hair loss after pregnancy normal?
Yes, hormonal changes can cause temporary effluvium.
Hair loss typically starts 2–3 months after giving birth and often resolves on its own.
Which blood values are relevant for hair loss?
Depending on the case, we may check levels like iron, ferritin, thyroid hormones, vitamin D, zinc, or other specific hormones to detect deficiencies that may affect hair growth.
How does autologous blood therapy help with hair loss?
Autologous blood therapy uses components of your own blood that are injected into the scalp. It can support hair roots and may complement other treatments. We’ll discuss individually if it’s suitable for you.
Do hairs grow back after effluvium?
In many cases, yes.
Once the cause is identified and addressed, hair growth can return to normal. Patience is key—first results may be visible after a few weeks or months.
Can genetic hair loss be stopped?
It can’t be fully stopped, but treatments can slow down the progression.
When should I see a dermatologist for hair loss?
If you’re unsure whether the hair loss is normal, if it appears suddenly, changes noticeably, or affects you emotionally—having it checked by a dermatologist is a good idea.
Is hair loss different in women compared to men?
Yes, in women genetic hair loss often appears as thinning at the part, while men may have receding temples or bald spots on the crown. Hormonal changes (like menopause) also play a bigger role in women.
