Are you wondering why you are losing your hair? The most common cause is genetic hair loss, but there can also be other reasons. We always evaluate each individual’s conditions to see if a hair transplant is the right way to treat their hair loss and to be able to get a natural and long-lasting result. 

Some people lose all their hair and some just get thinner hair. When and why this happens is different for everyone. Here you can read about some common situations and learn more about different reasons behind hair loss.

1. Genetics

Genetic hair loss is the most common type of hair loss and only affects hair on the top of the scalp and does not affect hair on the back of the head and on the sides. The genetic hair loss is caused by a type of testosterone called DHT. This kind of hair loss will therefore either slow down or stop completely in men around the age of 50 when testosterone levels drop and the effect of DHT on the hair follicles decreases. Even if you have genetic hair loss, you might not lose all your hair. At the consultation we always try to determine just how much hair you might lose over time in the future.

2. Age

Hair gets weaker with age which may cause it to fall off.

3. Stress and trauma

If you lead a stressful life, your testosterone levels can increase which will affect your hair growth. Stress and trauma can also constrict blood flow to the capillaries temporarily which affects the transport of nutrients, vitamins and oxygen to the hair follicles. There is therefore a big risk that stress and trauma can accelerate the effects of genetic hair loss.

4. Diet

A bad diet or rapid weight loss can affect hair growth. That is why it is important to eat a balanced and nutritious diet containing biotin, iron, protein and zinc, and limit the intake of animal fats.

5. Drugs and medications

Some drugs and medications can accelerate genetic hair loss, or even worse, cause a temporary or permanent hair loss on their own. This may be true for some medication given to patients with thyroid disorders. Hair that falls off during a chemo treatment will usually grow back, but not always. Hair loss can also be a consequence of diabetes. Contraceptive pills, blood pressure medication, heart medication and drugs that contain steroids can affect or cause hair loss.

6. Hormonal changes

Hormonal changes during a pregnancy can cause temporary hair loss, which can occur up to a year after the child is born. In many cases the hair grows back, but for some the hair loss becomes permanent. Women going through menopause can also experience hormonal changes that cause hair loss. Female hair loss is more common than people realize and affect around 30 percent of all women. At Poseidonkliniken we perform hair transplants on women.

7. The environment

Environmental pollution in the air and water, and chlorine, metals and minerals can create a hormonal imbalance which can lead to hair loss. UV light can also damage the hair, so it is a good idea to protect the hair against strong sun light.

We recommend:  A wide brimmed hat can protect both the skin on your face and the hair on your head from being damaged by UV light and prevent photoaging.


Typically, genetic hair loss starts at the temples, continues down over the crown and then forward again towards the hairline. The last hair that falls off is usually the hair that grows at the front in the middle of the hairline. During a hair transplant we extract hair that grows in the back of the head and move it to the areas on the scalp that are affected by hair loss. At Poseidonkliniken you can have a hair transplant done in a couple of hours, and after the treatment you can go home and live life as usual. The traces from the procedure will disappear in a week and the new hair will start to grow right away.

– Our treatment method is very gentle and quick, so it suits anyone who leads a busy life and does not have time to take days off work to have a treatment done, says Gustaf Bodin at Poseidonkliniken that has performed thousands of hair transplants and has treated celebrities such as Andreas Carlsson, Anders Limpar and Jan Johansen.


The first step to a successful hair transplant starts with a personal consultation where we design and tailor the procedure according to your needs, conditions and expectations - to achieve the best possible result.
