In 80% of all cases, it is "androgenetic alopecia" that worries men: Hereditary hair loss is a predisposition and not a disease. Therefore, it can not be cured once and for all but must be treated continuously. Furthermore, androgenetic alopecia is passed down dominantly. As a result, the cosmetic solution is appropriate for long-term treatment, because pharmaceuticals that involve the risk of undesirable side effects are not necessarily required to treat a cosmetic problem.
The testosterone surplus, which begins during puberty, makes beard hair grow on the one hand but also weakens predisposed hair roots in the scalp. Based on the hereditary disposition, the hair roots react supersensitively to testosterone (DHT). It cuts the energy supply, thereby weakening the hair roots. Their growth phases are shortened and their lifetime ends prematurely.
Normally, the hair root is active for up to eight years (growth phase), followed by a resting phase. The hair root releases the hair and it falls out without the threat of hair loss. Subsequently, the hair root starts another growth phase and does so about 14 times before dying.
With the corresponding genetic predisposition, testosterone (DHT) prevents the generation of c-AMP, a messenger compound for energy, which is required for the hair roots' metabolism. This shortens growth phases and the hair roots' lifetime ends prematurely. If more and more hair roots die this way, male baldness will be the result.
