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.
Androgenetic Alopecia slowly causes the hair follicle to shed the normal hair and produce thinner hair until it dies causing permanent hair loss. For this reason we highly recommend to consult a physician to treat the problem right on time.
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.
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.)
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.)
The treatment’s evaluation will be personalized by the physician in charge according to the class of alopecia. The causes of female alopecia are more complex than those of male alopecia and they have to be looked into.
It is becoming a more frequent clinic problem in women every day. . At present it is said that 25% of white females present FAGA at the age of 35-45 and a 35-40% present FAGA at around 50. This is important taking into account that hair loss has a bigger psychological impact on women than on men.
Female alopecia is caused by a genetic predisposition of the hair follicle with normal levels or with mild or severe androgen level growth.
One of the characteristics of FAGA is that it starts by diffuse hair loss in the parietal and vertical frontal region, in the crown, not involving the frontal hairline. Women do not suffer from total alopecia but their hair grows smaller in diameter, becomes thinner, shorter, making it possible to see the scalp; this is what Ludwig called “Miniaturization”.
After menopause 20% of women suffer from significant hair loss as a consequence of a decrease in female hormones. Then testosterone that already exists at normal levels becomes present together with a genetic predisposition. These have an impact on women that may result in low self-esteem and depression.
Polycystic Ovary (multiple cysts in the ovaries): This disorder presents high androgenetic hormone levels that produce among other consequences, androgenetic alopecia; already explained above.
The use of hormones such as testosterone, progesterone; Suprarenal disorder; Hypophisis disorder:
These cause an excessive production of masculinizing steroids (virilization). A consequence is alopecia and excessive hair growth and it is frequent after menopause and in people who take anabolic drugs.
There may be an alteration in the production of proteins transporting sexual hormones, increasing the quantity of free testosterone with an increase in the conversion process of this hormone into DHT that produces androgenetic alopecia.
Thyroid disorder: An excessive increase of thyroid hormone levels (hyperthyroidism) as well as a reduction of thyroid hormone levels (hypothyroidism) may cause alopecia. Hair loss associated to a thyroid disease may be reverted with an appropriate treatment.
Idiopathic: Without apparent cause, with normal hormonal levels but with genetic predisposition.
Successful therapy depends on directing a treatment at the underlying causes of hair loss and at the same time getting the appropriate medical treatment prescribed by specialists.
Some obsolete and deceitful techniques are still being performed nowadays to recover one’s hair or to stop it from falling off. These methods result in useless and anti-esthetic solutions. Some examples are:
Hair and scalp massage is absolutely useless since baldness does not result from poor circulation but from a number of hormonal and hereditary factors. Hair massage could, in no way, modify the hair’s genetic code.
