Every day some hair falls from the head. Again it is filled in the normal way. But a little too much can lead to anxiety and depression. One of the regular concerns of people seen by dermatologists in clinics is this excess hair loss. The level of recourse to experts in solving the problem has been increasing at an alarming rate in the last few years. Why is excess hair shedding? It is also very important to know why the hair is falling out like this. Hair cells have their own life cycle. Its growth phase, persistence and subsequent shedding. But sometimes that life cycle can be disrupted. Stress, poor quality of life, lack of balanced diet, not sleeping properly or insufficient sleep can also cause hair loss. In addition, hormonal imbalances and excessive travel can cause hair cell life cycle problems. If the hair falls out over a long period of time, it should be permanent hair loss. And if the hair loss is more severe, it can lead to hair loss in a short period of time. If this happens regularly, the head will become bare and bald. Vitamin B12, vitamin D3 and iron deficiency or anemia, hormonal imbalance or insulin resistance, PCOS (polycystic ovary syndrome, thyroid deficiency or increased stress and after that period, illness or pregnancy) can cause hair loss. In that case, you have to check to avoid this situation. After eliminating all these deficiencies and imbalances, some important facts should be kept in mind.
