The causes of hair loss are numerous. Diffuse hair loss: androgenetic alopecia, telogen effluvium, anagen effluvium, alopecia areata Among the diffuse hair loss, the most common are the common hair loss (androgenic alopecia male and female) and telogen effluvium (after a high fever, pregnancy, drug taking or a strict diet). The anagen effluvium in turn causes a sudden loss of hair after chemotherapy or during alopecia areata. The genetic hair loss occur at birth or rather during childhood (moniletrix syndrome of anagen hair, ectodermal dysplasia). Localized hair loss: androgenetic alopecia, alopecia areata, cicatricial alopecia, tumors The localized hair loss occur in the context of male androgenic alopecia (gulfs, tonsure), fungal infections (ringworm), alopecia areata in plaques, alopecia induced by pulling (trichotillomania, braids and hair straightening) or cicatricial alopecia (lupus erythematosus, lichen, folliculitis decalvans, central centrifugal scarring alopecia, frontal fibrosing alopecia in postmenopausal ...). Tumors and skin growths are also accompanied by hair loss localized (sebaceous nevus, basal cell carcinoma, squamous cell carcinoma). Stress and hair loss Responsibility stress has often been implicated in the onset of hair loss but has not hitherto been confirmed by scientific studies. However, we are all victims of stress induced by the events of everyday life, we must consider the role of stress when hair loss occurs in significant weeks of emotion intensity abnormally high. Treatment of hair loss Effective treatment of hair loss needs to determine the cause. †The telogen effluvium may indicate support for a deficiency (iron, vitamin B12) or a thyroid problem but they usually heal without treatment after 3 to 4 months (after pregnancy, fever, surgery, ect ...). The telogen effluvium induced by taking medication (isotretinoin, cholesterol, blood thinner ...) where possible require replacement therapy with another molecule. †The anagen effluvium chemotherapy may, to some extent be minimized by preventive measures (cooling helmet). †The skin and systemic conditions that cause hair loss should receive specific treatment tailored to each case. Ringworm requires antifungal therapy systemically. Treatment of lichen uses topical steroids, intralesional or general and sometimes synthetic antimalarials (Plaquenil). The cicatricial alopecia treatment are difficult, they require the use of an expert from the scalp. Once the reconstruction process stabilized by hair transplant is sometimes possible. †The Congenital alopecia may sometimes benefit from hair restoration through hair transplants or hair supplements. †Alopecia areata in small plates often heal quickly without treatment but may recur while alopecia most important involve rapid response that involves the topical steroids (lotion), intralesional (injections into the scalp) or rarely in the corticosteroid General. PUVA, the dioxyanthranol and application of a sensitizing substance (diphencyprone) treatments are often recommended. †The male androgenic alopecia benefits of treatment with finasteride (Propecia ) and minoxidil 5%, dutasteride has demonstrated its superiority over finasteride in a large U.S. study, it has not yet authorized release on market in this indication. When the hair has completely disappeared from an area, hair transplants are the only way to "Most natural hair. Current techniques of follicular grafts yield excellent results when performed by expert teams. †The female androgenic alopecia is a common treatment is called minoxidil 2% or 5 and antiandrogens (cyproterone acetate, spironolactone) when hyperandrogenism is manifest finasteride or dutasteride are not currently indicated but not finasteride is being evaluated in postmenopausal women.
