1 – Hereditary hair loss

The most common cause is hereditary hair loss. About 80 % of men who lose their hair prematurely suffer from this form. This type is also known as male-pattern hair loss.

Testosterone is converted into dihydrotestosterone (DHT) by the enzyme 5-alpha reductase. Many hair follicles react sensitively to DHT and atrophy. The hairs in question become shorter and thinner until they disappear completely.

The first signs are often seen in the mid-20s with hair loss at the temples. As time goes by, this may eventually result in full baldness.
 

2 – Stress-related hair loss

Stress can trigger hair loss and its impact should not be underestimated.

Besides excessive exercise, lack of sleep and other physical stress factors, psychological problems can also be reasons for hair loss.

The longer the stress lasts, the more the hair suffers. The hair needs a sufficient supply of energy for healthy growth. If the body uses energy elsewhere in stressful situations, there is not enough left to nourish the hair.
 

3 – Spot baldness

Spot baldness is a form of hair loss. This is believed to be triggered by an autoimmune disease.

Spot baldness therefore occurs relatively rarely and is characterised by the typical round bald patches on the head and also on other parts of the body. Often the bald patches disappear after a while, but can reappear later.

4 – Diffuse hair loss

This is characterised by the fact that the hair becomes altogether lighter.

The reasons for diffuse hair loss can vary and range from an unhealthy lifestyle to an illness, from medication to stress.

The hair roots do not receive the necessary nutrients they need for growth and the hair falls out.
