Hair follicles are unique structures with exceptional regenerative potential.
They are believed to be crucial for epidermal Hair Lossostasis and
reepithelialization after damage to human skin. Like other, more active and
quickly proliferating organ systems, hair follicles may be easily disturbed in
their normal growth cycle by systemic and local influences, including specific
skin diseases.
This may lead to hair loss, a very common complaint in men and women. The difficulties in reviewing the diseases of hair follicles lay in the long list of different etiologic factors (infectious, autoimmune, inflammatory, neoplastic, physical, chemical, congenital) and a still missing classification system according to etiopathogenetic principles.
In this article (Part I of II), the structure and function of hair follicles,
the diagnostic approach to diseases causing hair loss, and the most common
nonscarring alopecias (telogen effluvium, anagen effluvium, androgenetic
alopecia, and alopecia areata) are reviewed in regard to pathogenesis, clinical
findings, and current options of treatment. Part II will focus on scarring
alopecias.
