Alopecia can affect any area of the scalp, often several areas of different sizes and with different intensity.
The beginning of hair loss tends to be sudden, random and often recurrent. Before capillary micropigmentation treatmentthere wasn't a real solution to the alopecia. It is worth noting that alopeciais not detrimental to someone's health; however, it can have significant impact on their confidence.
AtEDM, we have an excellent history of customers who suffer from many types of alopecia; below you can see different types of alopecia which we are accustomed to treating.
There are many types of alopecia and they can be classified according to their origin and manifestation, but androgenetic alopecia is the most frequent. It is linked to the genetic inheritance of each individual (hereditary component) and due to hormones. Starting from puberty, the influxes of male hormones (androgens) tend to slowly stunt the follicle hair, which eventually leads to a shortened lifespan of hair after many decades.
Other common forms of alopecia are:
There are many less frequent varieties of alopecia that can be originated due to genetic causes, medications, skin infections, trauma, nutritional deficiencies and certain skin or general diseases.
Androgenic alopecia, also called androgenetic alopecia,common alopeciaor male pattern baldness, is the most frequent type, accounting for 95% of cases.
It mainly affects men, but it can also affect women; it is most common in Caucasians.
It is calculated that at the age of 50, it is present to a greater or lesser degreein 55% of Caucasian men and about 10% of Caucasian women.
Two factors should be highlighted in its etiology: genetic and hormonal. Although there is a hereditary component, it is unknown which gene is responsible, as it is part of a polygenic dominant heritage; the hormonal factor fundamentally depends on male hormones or androgens that act on hair follicles which aregenetically predisposed to the condition, causing it to progressively diminish until it reaches full atrophy and fibrosis.
This is atype of hair loss that causes round patches. Its etiology is not yet known, but it is associated with situations of stress, and on occasions it could be due to an autoimmune substrate.
In most cases, this condition only affects onespot (Alopecia areata monolocularis) and usually heals spontaneously, but it can also extend to the entire head (alopecia areatatotalis) or the body in its entirety (alopecia areatauniversalis).
Hair follicles aren't destroyed with this disease, which is why hair often regrows, although it is also true that sometimes there are relapses in patients who have had it at some point in the past.
According to several studies, the presence of infectious foci of the teeth can cause alopecia areata and hair loss in some areas of the scalp.
Alopecia areata universalis is an autoimmune disease, in which the body produces antibodies against a part of the hair follicle.
It is the most extensive variant of alopecia areata, which is actually the same disease but much less severe.
The cause of alopecia areata universalis unknown. Some believe that it is hereditary as a part of several autoimmune diseases, but only one in five patients present a family history of alopecia universalis.
This disease causes total hair loss, i.e. the absence of hair all over the body, not just the head. It shouldn't be confused with androgenic alopecia. Under regular conditions, the scalp constantly produces hair.
In patients with alopecia universalis, the affected hair suffers a very noticeable decrease in hair production. Scalp follicles remain under the skin in a hibernation state and they can restart producing hair again when they receive the proper signal.
