MaleBaldness
From the age of 25 onwards, 90% of the male population suffers from androgenetic baldness or male pattern baldness. It is called androgenetic baldness because it is determined by heredity and androgens, which are the hormones responsible for hair loss. For this reason, current oral treatments inhibit the production of this hormone to prevent hair loss, but only in certain areas.
If baldness continues to progress and the hair follicles die, the process becomes irreversible and there is no treatment to restore the situation. The only solution in these cases is micro hair transplantation.
In certain cases, baldness can manifest itself in a diffuse manner, i.e. it can begin to lose density without necessarily following the progression from front to back.
In male pattern baldness the hairline recedes and takes the shape of an ‘M’, gradually the bald area of the crown will join the upper bald spots and form a kind of ‘horseshoe’ at the back of the head.
Since baldness is usually progressive, - according to the visual pattern of baldness that was inherited, - Norwood defined the degree of evolutionary baldness from grade I, - which represents a hairline with zero hair loss, to the extreme grade VII, in which hair loss is manifested in the entire upper and back region of the head, leaving only hair on the sides and back of the head.
Norwood-Hamilton Scale for the Classification of Androgenetic Baldness
Norwood Type 2
The fronto-temporal region begins to retract the frontal hairline and the frontal hairline proceeds and markedly defines the so-called ‘receding hairline’ which tends to be symmetrical or asymmetrical.
A slight hair loss begins and the density decreases in the frontal part. When a hair transplant is performed at this stage, the results are usually excellent.
Norwood Type 3
Although hair loss is usually minimal, this is the first degree that is already considered baldness.
In type 3V (Vertex) hair loss also occurs in the crown area and is usually delayed over time.
Hair transplantation together with some prescription treatments in this condition has excellent results.
Norwood Type 4
This is clearly a more advanced degree of baldness. We can observe that the recession in the frontal and frontal temporal area is more pronounced. The density of the hair is noticeably reduced, in the same way that happens in the crown area.
A single session of hair transplant, excellent results are obtained and still in this state the treatments can help but only as a complement to stop the hair loss.
Norwood Type 5
The fringe of hair separating the crown and temporal frontotemporal areas begins to disappear.
Now it looks like a generalised baldness but in reality it is deeply localised in both areas.
It is quite advanced baldness and treatments - non-surgical - definitely do not help.
Norwood Type 6
In type VI the bridge or fringe separating the two areas has certainly disappeared. The baldness begins to spread laterally and towards the posterior area.
Norwood Type 7
Type VII is the most advanced degree of baldness. Hair is only present on the nape of the neck and on the sides (above the ears). In these degrees, there is no treatment, drug or lotion that can help. The only permanent solution for these cases is micro hair transplantation.
