Hereditary predisposition
How strongly your follicles react to androgens is genetically determined. The predisposition can come from either parent.
Understanding hair loss
We explain the biological basics of hereditary hair loss, the role of DHT and known active ingredients. You learn which mechanisms matter and where a physician's assessment remains necessary.
How hair loss happens
Hereditary hair loss follows known mechanisms. These three matter most.
Simplified illustration of hereditary sensitivity, DHT signals and shrinking sensitive hair follicles
DHT as the trigger
The enzyme 5-alpha-reductase converts testosterone into DHT. On sensitive follicles, DHT shortens the growth phase.
Shrinking follicles
With each hair cycle the affected follicles shrink. Strong hairs become finer and shorter, until they stop growing.
What this means for you
Use this page as a clear orientation: which types of hair loss exist, which mechanisms matter and which treatment questions can be assessed by a physician. The links take you deeper into hair loss types, mechanisms of action, use and possible risks.
Hair loss types
Active ingredients
The type makes the difference
Androgenetic alopecia, diffuse shedding and other patterns do not have the same causes. That is why it helps to look at progression, pattern and possible triggers separately.
The mechanism explains the approach
DHT, the hair cycle and follicle miniaturization help explain why active ingredients work in different ways and why results take time.

With this foundation, it is easier to understand which details matter, which risks need to be checked and which options a physician can assess.
