Most men and women suffer from some type of unusual hair loss at some point in their lives, either in a temporary or permanent way. It can even be suffered by children.

There are two possible attitudes against this fact: acceptance or rejection. The latter, is what generates one of the most common reasons to consult dermatologists due to the cultural and social importance that hair has acquired in our current society.
(hair = beauty, youth, personality, safety).


Hair loss is technically known as ALOPECIA. The word "alopecia" comes from the Greek term "Alopex" which means "fox", as foxes loss their hair/fur twice a year. According to the dictionary definition alopecia is: "hair fall or pathologic hair loss”; a definition more than right.


To understand the reasons why this happens, it is important to learn about normal hair growth. The capillary cycle is not syncronised in humans, thus while some hair is falling out, others are growing.

"Approximately 90% is continuously growing. The other 10% is in a resting phase that lasts from 2 to 3 months. After this resting phase, the hair falls out".

In normal conditions, hair grows 1 centimeter per month; we have about 100 thousand and 120 thousand follicles in the scalp, each of them forming a hair and normally we loss between 50 and 100 daily. The growing phase is of variable duration (depending on each person, climate and time of the year) and it can last from 2 to 6 years, that is why certain people can have very long hair while in others the hair length has a certain limit.

Hair structure

Treating quickly the first visible signs of hair loss, we will have more possibilities of keeping, for longer, our hair strong and healthy


As a group alopecia represents more than 8% of the dermatologists consultations. When hair loss, therefore hair falling out in large quantities turns to be obvious, it means that a larger quantity of hair has gone into the falling out period, and this can be due to different factors, which are multiple, and they allow for the classification of alopecia in two main groups: non cicatricial (scarring) or cicatricial (scarring) that at the same time can be congenital (not very common, those in which there is no hair from birth) or acquired.

The non cicatricial ones are the most common and can be improved or cured through treatments,

such as the products from the Keravit range, and even in some cases they can be reverted spontaneously with no treatment at all. In this type of alopecia the hair follicle has a pathologic behaviour but carries on being alive unless the alopecia is extended in large periods of time (common alopecia or androgenic).

The common baldness or androgenic alopecia is the most frequent one and it is suffered by 95% of the people that suffer from hair loss. The male hormones (androgens) are responsible for hair loss in people genetically predisposed.

According to different statistics it would have an effect on over 25% of men between 25 and 35 years old, 40% of men older than 40 and 50% of men older than 50 years old, increasing the percentage as age we look into more advanced age groups. Women could suffer from it at around the 28%, although there are no large studies concerning the subject. The hair loss starts at the crown of the head (vertex) or in the frontal area (commonly known as receding hairlines). As time goes by alopecia becomes gradual and advances if the adequate treatment is not started in an early stage.

First way to detect hair loss

Keravit® anti-hair loss treatment ampoules with PRO-ANAGEX®, acts efficiently and directly on the hair root and stops hair loss by 90%.


Classification according to the Norwood scale

The frontal area shows small receding hairlines that tend to be symmetric. A slight hair loss starts to take place and the density decreases in the frontal area. When the treatment starts at this stage, the results are normally excellent.

Although there is minimum hair loss, this is the first level considered as alopecia. In type 3V (Vertex) the hair loss is also shown in the crown area and tends to increase with time. The treatments at this stage are normally very successful.

This is clearly a more advanced level of alopecia. We can notice that the receding process in the frontal and frontal-temporal areas is much stronger than in level III. The hair density is remarkably reduced in the same way as it happens at the crown area. Even at this stage the treatments may offer good results.

The stripe of hair that separates the crown and front temporal areas starts to disappear. Now it looks as general baldness or alopecia but it is really deeply located in both areas. It is a very advanced stage of baldness and treatments –non surgical- help very little and in very few occasions.

In type VI for sure the bridge or stripe that separated both areas, is gone. The baldness starts to spread over the sides and towards the back part of the head.

El tipo VII es el grado más avanzado de calvicie. El cabello solo existe en la zona de la nuca y en los laterales (arriba de las orejas). En estos grados, no existe ningún tratamiento, droga o loción que pueda ayudar.
