Hair loss, known medically as androgenetic alopecia, seborrheic alopecia or common baldness, is caused by a progressive loss of hair. The first thing that strikes the patient is increased hair loss especially in the wash and hairstyle. The loss of up to 25 hairs per day, indicating excellent health of the scalp.
Between 25 and 50, can be quantified as normal, but a fall of over 50 hairs must be seen as excessive, whichever take precautions.
Androgenetic alopecia is a physiological phenomenon multifactorial
Genetic causes: it depends on the stimulation by androgenic hormones in genetically predisposed follicles.
Androgenetic stimulus: a stimulus is presented androgen on the sebaceous secretion, by androgenic hormones.
Decreased cell activity: it relates to the passing of the years in response to decreased cellular activity of hair follicles, similar to what happens in the rest of the body.
Dysfunctions in sebum secretion: in those affected by common baldness, there is a significant increase in sebum production.
Peeling pityriasis altered: the accelerated production of basal cells extract quickly pushed to new keratinocytes to the surface for complete keratinization, resulting in a hasty and faulty keratinization which leads to increased scale, rapid cell turnover and appearance of fungi and bacteria propiciantes the onset of common baldness.
Circulatory: generally decreased blood microcirculation leads to less blood supply, which reduces the materials necessary for proper metabolism in hair follicles.
Organic factors: such as diet and psychological factors like stress or depression.
