Hair loss can be caused by different factors such as medical conditions, inappropriate care, genes. Your dermatologist will ask you questions about your eating habits, medication (including vitamins and food supplements), family history, hair care habits, recent diseases. In women, hormonal factors are also important, so you can be asked about pregnancy, menstrual cycle, menopause. When hair grows normally, 90% of it is in a growth phase, and the other 10% – in a rest phase, which lasts 2-3 months. At the end of the rest period, the hair falls, and a new one grows from the same follicle taking its place and continuing the cycle. Most hair loss is normal as a loss of this cycle, and a loss of 50-100 hairs per day is ordinary.
Factors contributing to hair loss are:
oral contraceptives – usually due to a hereditary tendency of hair thinning, a change in the contraceptive usually solves the problem, 2-3 months after the patient stops using oral contraceptives hairloss similar to the one after pregnancy can occur;
giving birth – more hair follicles are in a growth phase during pregnancy, after giving birth, however they are in a rest phase; hair loss can last 2-3 months
hereditary hair loss and balding – the most common reason for hair loss, can be inherited from the parents and usually doesn’t end in complete hair loss in women;
insufficient protein – insufficient quantities of protein in the diet can cause hair loss, treated with dietary changes;
unsuitable hair care or cosmetic procedures – chemical therapies of the hair can lead to hair loss when they are improperly done or too frequent; tight hairstyles can also cause hair thinning, and so can too frequent brushing or using of shampoo; drying wet hair with a towel;
low levels of iron – iron deficiency anemia can lead to hair loss;
surgery or chronic diseases – after surgery – usually the problem solves itself in up to a few months; patients with chronic diseases can experience hair loss for a long time;
