Cause della caduta di capelli abbondante
Among the most frequent causes of temporary and occasional hair loss we find the change of season and therefore the seasonal defluvium, typical of the spring and autumn period, in addition to low-calorie diets, childbirth and breastfeeding, periods of psycho-physical stress (work stress, hectic pace) and air pollution. In these situations, a more abundant fall from the whole head is observed, the hair has a fragile and devitalized appearance, and, unless other factors, it is a transitory situation, often self-healing.
Conversely, when factors concomitant to genetic ones, cause alteration of the physiological cycle, mainly the premature initiation of the resting phase (telogen) for numerous follicles and also thinning of the hair shaft (miniaturization), it is probably the initial phases of of alopecia. The hair loss is therefore abundant and continuous, prevalent in some areas of the head, with thinning and visibility of the scalp as well as the appearance of the hair not very voluminous because the hair that grows back thinner than normal does not have much volume.
Unlike the temporary and occasional fall, alopecia is a chronic condition, therefore constant and progressive, destined to worsen.
The nutritional aspect is of great importance, because the activity of the hair follicles can be influenced by malnutrition, both in terms of calories and protein and micronutrient deficiency. Nutritional deficiencies can affect both the quality and the growth capacity of hair.
The micronutrients to pay particular attention to, because they are more involved in hair loss, are: Iron, Zinc, Selenium, to which vitamin H or Biotin is also added.
Chronic stress, alcohol abuse, the habit of smoking are other factors that negatively affect the health of the hair, favoring oxidative stress.
There are also some daily habits that are not healthy for the health of the hair, such as not washing your hair frequently, for fear of further weakening it.
Obviously washing and combing are two actions that tend to make the hair fall out, but only those that are now weakly anchored to the follicle and therefore destined to come off anyway.
Instead, it is important to know that sweat, together with smog and sebum, further worsens the health of the follicle, favoring the production of free radicals.
