In this study, we have presented consequences of nutritive deficit on status of pilosebaceus follicle at two groups of examines, dermatological patients and patients who were wounded and/or operated, and without manifest signs of alopecia. Values of serum's iron, factors of saturation of iron, Hb, hematocrit and state of protein metabolism, were not in all cases, complementary with prescription of trichogram. Telogenic defluvium, dystrophic of mixed, has been found even at cases with normal (physiological) values of those parameters as consequence of high sensitive hair follicle to minimal deficit which is hand to detect by lab test. At group of patients who were wounded and/or operated it was found higher percent of dystrophic and mixed effluvium as consequence of hard damage of hair follicle. Percent of telogenic defluvium is the same at the both groups of patients. At this time, those damages are reversible in condition which permit normal diet and remove all physical and psychical of stress.
