We often hear the terms androgenetic alopecia and androgenetic alopecia when discussing hair loss. The two terms are often used interchangeably. However, there is an important difference between the two.
The role of DHT in hair loss
In both cases, the hair loss is linked to the action of androgen hormones, notably DHT (dihydrotestosterone), a hormone derived from testosterone.
DHT acts directly on hair follicles and causes what is known as follicle miniaturization. The hairs gradually become thinner and the growth phase shortens.
Over time, a loss of density and sometimes a widening of the line are often noticed.
Visually, androgenic alopecia and androgenetic alopecia are very similar. The main difference lies in the origin of this sensitivity to androgens.
What is androgenic alopecia?
Androgenic alopecia refers to progressive hair loss linked to sensitivity to androgen hormones or an excess of androgens in the body.
It generally manifests itself through:
-
a gradual fall
-
hair thinning
-
a decrease in density on the top of the skull
In this case, sensitivity to androgens is not necessarily genetic. It can appear due to various factors that disrupt hormonal balance.
Among the most frequent triggers:
-
hormonal imbalances
-
polycystic ovary syndrome (PCOS)
-
insulin resistance
-
chronic stress
-
nutritional deficiencies
-
certain medications
-
contraceptive pill
When it is linked to a hormonal imbalance, it is often possible to address the cause. For example, by improving stress management, diet, or by undergoing medical monitoring to identify the origin of the imbalance.
What is androgenetic alopecia?
Androgenetic alopecia is based on the same mechanism, but with one important difference: sensitivity to androgens is genetic. Therefore, there is not necessarily an excess of androgens, but rather a greater sensitivity to them.
The characteristics are the same. The difference lies in the fact that the predisposition is genetic and therefore generally permanent.
Since this sensitivity is genetically determined, it is often necessary to establish a daily hair care routine for life.
In summary, androgenic alopecia is linked to a hormonal imbalance or an excess of androgens, while androgenetic alopecia corresponds to a genetic sensitivity to androgens.
What can be done to slow down this type of decline?
Even though the origin is different, the mechanisms remain the same. Here are the essential actions to support the follicles:
-
Stimulate scalp microcirculation to improve the supply of nutrients and oxygen to the follicles.
Our Dermastamp No.1 creates controlled micro-perforations to stimulate the scalp. -
Limit the action of DHT on hair follicles.
The Anti-Hair Loss Serum No.1 It notably contains Capixyl™ and caffeine , two active ingredients known to help block the action of DHT locally at the scalp level.
What matters most is consistency. A hair care routine followed consistently helps support the follicles and promotes stronger regrowth.
