Other types of Hair loss
Non-hereditary hair loss occurs mostly in women and is predominately caused by hormonal disorders (pregnancy, menopause) by uncommonly stressful situations and overtiredness by "crazy" unhealthy diet or malnutrition (low vitamin, protein and trace mineral intake) by mechanical damage (repeated shampooing with "tough" shampoos, blow drying, excessive combing, hair bands) or chemical damage (hair coloring hair perms). Other factors that intensify the condition are the excessive sebum secretion, the intense dehydration of the scalp, UV radiation, pollution and environmental conditions (drought, wind). Finally there are cases of hair loss that are directly related to numerous conditions and the use of specific drugs. These cases are referred to as pathogenic hair loss and need the medical assist of a dermatologist.
