The Real Cause Of Baldness: Androgenetic Alopecia
More than 95% of hair loss cases are really caused by androgenetic alopecia, resulting from genetic and hormonal factors. This form of alopecia is characterised by affecting the frontal and top regions of the head but not affecting the back and sides of the scalp.
Contrary to what many people believe, baldness is NOT the consequence of stress, dandruff, seborrhea , malnutrition or poor circulation.
OTHER CAUSES OF BALDNESS
Each kind of alopecia has a pattern that is recognized by hair recovery specialists who know which is the right procedure to treat alopecia in the most effective way. The causes of alopecia or baldness will be divided in two broad categories:
CONGENITAL: This is rare and it is present since birth.
ACQUIRED: Cicatricial / Scarring.
- Non-cicatricial / Non-scarring
Cicatricial: occurs as a consequence of growth disorders and hereditary diseases, infectious processes, neoplasm, chemical / physical agents (radiotherapy, traumatisms, etc) This form of Alopecia is caused by loss of the hair follicle. It is irreversible unless through surgery.
Non-cicatricial: This form of alopecia occurs by hair loss and not by hair follicle loss; in some cases it can be reversible. Some categories within this group are:
Alopecia areata (associated to autoimmune diseases, triggered by psychical or physical stress. It presents as one patch with no hair at all or involves the entire scalp, alopecia totalis.)
Hormonal (thyroids, ovaries, hypopheses, suprarenal)
Nutritional deficiencies (proteic-energetic malnutrition, fatty acids, iron, zinc, biotin)
Pharmacological (blocking b, thallium, mercury, colchicines, methotrexate, some antidepressants and others)
Acute physical stress (high fever, hemorrhages, post partum, etc.)
