Causes of Hair Loss

Hair fall (45 to 60 per day) and renewed permanently. The normal hair loss is predominant in the late summer and spring. Hair loss hair above 60 per day is considered excessive.

The causes of hair loss are numerous.

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, a drug or a severe). The anagen effluvium leads about him a sudden hair loss after chemotherapy or during the pelade. The genetic hair loss occur at birth or rather in childhood (moniletrix syndrome anagen hair falling, ectodermal dysplasia).

The hair loss can be found in localized part of the male androgenic alopecia (gulfs, tonsure), infections by fungi (ringworm) of pelade plate, induced by the alopécies ups (trichotillomania, braids and hair) or cicatricial alopecia (lupus erythematosus, lichen, folliculitis décalvante, central centrifugal scarring alopecia, alopecia frontal fibrosing post-menopausal …). Tumors and skin growths also accompanied a localized hair loss (Sebaceous hamartoma, basal cell carcinoma, squamous cell carcinoma).

The responsibility of stress has often been the cause of hair loss but has not previously 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 the weeks following an emotion with an intensity abnormally high.

The effective treatment of hair loss needs to determine the cause.

• The telogenes effluvium may indicate support for a deficiency (iron, vitamin B12) or a thyroid problem but they usually recover without treatment after 3 to 4 months (after pregnancy, fever, surgery ect …). The Effluvium telogenes induced by a drug (isotretinoin anticholesterol, anticoagulant …) require whenever possible replacement therapy with another drug.

• The anagen effluvium chemotherapy may to some extent, be minimized through prevention (helmet refrigerant).

• The skin and the general conditions which cause hair loss should receive specific treatment tailored to the specific case. Ringworm requires an antifungal treatment by systemically. Treatment of lichen uses corticotherapy local or general Intralesional and sometimes synthetic antimalarial (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 an option.

• The congenital alopécies may benefit from a hair restoration by transplantation of hair or hair of an addition.

• The pelade small plates often heal quickly without treatment but may recur while pelades largest involving rapid that uses local corticosteroid (lotion), intralesional (injections in the scalp) or rarely corticotherapy General. The puvathérapie the dioxyanthranol and application of a sensitizing substance (diphencyprone) treatments are often recommended.
