ALOPECIA SCALES

Norwood-Hamilton Scale (Male Pattern)

 

The name of the male pattern is due to the first people who performed an alopecia scale. The first doctor was James Hamilton who made the first scale of alopecia and had a classification of up to 8 degrees.

Dr. Norwood made a scale of up to 7 degrees, simplifying the first scale.

The hair has a normal state. There may be a minimal recession in the frontotemporal zone. Hair loss in this phase is the usual one.

The most affected area is the frontotemporal, with recessions of 2 cm. If we are in this degree, the hair begins to fall out as well as a decrease in density in the front.

In this degree, we can already be talking about a baldness, it presents with hair loss in the crown and the known entrances in with little hair or with absence of it.

Here we find an advanced state of baldness, here the areas of the crown and the entrances are connected.

In this degree it is very common that the bridge between both sides of the head has not been completed in an integral way. The area affected by baldness are the front and crown, which is getting wider.

In this degree there is a total disappearance of the bridge that separates the areas most affected by baldness.

We are at the last degree of the scale, and there is only the presence of hair on the top of the ears and on the back of the head.

Ludwig Scale (Female Pattern)

 

The Ludwig Scale or Female Pattern was developed by Dr. Ludwig. The difference between the male pattern is that it is divided only into 3 degrees and in very rare cases we find 2 degrees more.

Baldness in this phase is classified as mild and its presence is not very evident in the central hairline.

We find a baldness called extensive and is present throughout the upper area, being the crown the most affected part.

We find ourselves in a total loss of hair being more similar to the male pattern.
