Hereditary hair loss

by Pia Wolter on Jan 15 2026

Hereditary hair loss, also known as androgenetic alopecia, is a form of hair loss caused by genetic predisposition. The cause of hereditary hair loss is an excess of male sex hormones, particularly testosterone, which leads to a shortened growth phase of hair follicles in the scalp.

This results in a reduction in hair density and ultimately hair loss.

Who is affected?

Men are more frequently affected by hereditary hair loss than women, but women can also be affected. In both sexes, hair loss typically occurs on the forehead, temples, and back of the head. Hair loss usually begins between the ages of 20 and 30 and can gradually develop over several years. Typically, hair loss in men begins with a receding hairline, which can develop into baldness over time. Hair loss in women, however, often manifests as a thinning of the hair at the crown.

Androgenetic alopecia is influenced by genetic factors and is therefore not preventable. However, there are various treatment options that can slow down or even stop your hair loss. It is important to see a doctor early if you suffer from hereditary hair loss, as early treatment yields the best results. In addition, self-help measures such as a healthy diet, sufficient sleep, and stress management can help slow down your hair loss.

What does testosterone have to do with hair loss?

In genetically predisposed individuals, the influence of testosterone on hair follicles leads to a shortened growth phase, ultimately resulting in reduced hair density and hormonal hair loss. Both men and women can be affected by this form of conditional hair loss due to this hormonal imbalance, which is why it is also known as hormonal-hereditary hair loss.

Dihydrotestosterone, often abbreviated as DHT, is a biologically active metabolite of the male sex hormone testosterone. It is formed by the conversion of the hormone testosterone with the help of the enzyme 5-alpha-reductase. DHT plays a significant role in the development of hormonal-hereditary hair loss. In hair follicles that are genetically susceptible to this hair loss, DHT binds to receptors and causes the hair's growth phase to be hormonally shortened. This, in turn, leads to a gradual reduction in hair density and ultimately to hair loss from the hair root.

Symptoms

The symptoms of hereditary hair loss often begin with a gradual reduction in hair density, especially at the forehead, hairline, and temples. In men, hair loss can also appear at the back of the head. Women are often less severely affected, and there may be a general thinning of the hair, similar to diffuse hair loss.

Further symptoms may include:

  • Receding hairline
  • Hair loss in the form of receding temples
  • Visible bald spots on the scalp
  • Increased hair shedding when combing or washing
  • Slow progression of hair loss over time

It is important to note that hereditary hair loss is a natural process and is often determined by genetic factors. There are various treatment options, such as medications or special care products, to slow down or stop hair loss. I advise you to consult a dermatologist if you experience persistent hair loss to receive an individualized treatment recommendation.

The seven stages of hair loss

Have you ever heard of the Hamilton-Norwood scale? It is, so to speak, the typical progression for hereditary hair loss. This scale, named after researchers James Hamilton and O'Tar Norwood, is used to classify male hair loss into different stages. It visualizes how hair loss can develop over time. The scale ranges from stage I to VII, with stage I representing minimal hair loss and stage VII representing advanced hair loss, including baldness.

For men, the Hamilton-Norwood scale is particularly useful for determining the current state of their hormonal hair loss and exploring possible treatment options. It enables precise communication between affected individuals and doctors about the degree of hair loss and helps in establishing individual therapy approaches. This scale is therefore not only

a table of numbers, but a valuable tool for better understanding the type and progression of hair loss.

Consequences

The consequences of hereditary hair loss can be very distressing for you as an affected person, as hair is an important part of one's self-image for many people. Progressive hair loss due to hereditary alopecia can lead to insecurity and feelings of inferiority.

Affected individuals may lose their self-confidence and feel unattractive. Do you perhaps also know what it's like to constantly compare yourself and feel bad when you see other people with full and healthy hair? This can lead to severe emotional distress that can significantly impair your quality of life.

Always remember that hereditary hair loss is a natural and common phenomenon that affects many people. It is important to accept yourself and accept that your hair loss may be part of your life. There are also various treatment options, such as hair transplants or medical therapies, that can help stop or reduce hair loss. It is important that you take care of your own health and well-being and not let yourself be defined by external appearances.

Treatment options

There are various treatment options for hereditary hair loss, including medications that can slow down or even stop hair loss, as well as surgical procedures that promote hair growth. In addition, special care products like our FullHair Hair Capsules or the FullHair Hair Serum can strengthen and support your hair growth.

In advanced stages, a hair transplant may also be considered. However, it is important to note that these treatments can vary in effectiveness and there is no complete cure for hereditary hair loss.

Prevention

Unfortunately, there is no way to completely prevent hereditary hair loss. However, there are some measures that can help slow down the progression of your hair loss. These include taking special medications that can reduce your hair loss, as well as using special care products. A balanced diet and regular exercise can also help promote hair growth and slow down hair loss. However, it is important to note that these measures are not equally effective for everyone.

It is always advisable to consult a dermatologist or a specialist in hair loss to find the best individual treatment options. It is also important to always be patient and not let your hair loss weigh you down too much, as this can often lead to a vicious circle that even accelerates hair loss. Inform yourself about the possible treatment options and seek support from specialists to achieve the best result.

Remember that true beauty comes from within, and you are so much more than just your hair. If hereditary hair loss ever gets you down, be

kind to yourself. A visit to the doctor can work wonders, and there are so many ways to approach this process.

Remember, we are not alone on this journey. Health and self-love are our best companions. Together we can do this!
