Hair loss is a common phenomenon experienced by every individual. As hair falls off the scalp, it is usually replaced with new strands of hair. This is a natural process adopted by the body to renew itself. There are numerous causes of hair loss. Hair loss might be either temporary in nature or permanent.
Some of the common causes of hair fall are:
People suffering from illnesses for a long duration or undergoing a surgery, may suffer from heavy loss of hair. This kind of hair loss is usually temporary and happens because of the stress caused by the illness or surgery.
Hair loss may occur due to consumption of certain drugs. Such kind of hair loss is also usually temporary in nature and stops when you stop taking the medication. Drugs prescribed for diseases such as gout, heart problems, depression, high blood pressure, arthritis, etc. might cause hair fall. Medicines used in chemotherapy to treat cancer causes heavy hair fall.
Males and females have hormones called androgens and estrogens respectively. If these are not in balance, they may cause hair loss. Also, if the thyroid gland is overactive or underactive, there may be hair loss. In such cases, you need to treat the hormones.
During pregnancy, women experience various hormonal changes. During this period, women have high levels of progesterone and low levels of estrogen in their body. This also causes hair loss.
The oil that is secreted from the scalp is called sebum. This often blocks the pores of the scalp and impairs follicle growth. If not cleaned timely, the sebum turns into wax that permanently blocks the pores that results in hair fall.
Often, insufficient flow of blood to the scalp and low levels of nutrients in the blood causes hair loss.
In order to fight hair loss in such cases, you need to increase the blood to your scalp.
It is very important to maintain sufficient intake of protein in your diet. Low amounts of protein in your diet can lead to heavy shedding of hair. With prolonged protein deficient diet, hair becomes so weak that you can easily pull out strands of hair from your scalp.
Many kinds of hair styling treatments such as dyeing, tinting, bleaching, straightening, etc. can damage your hair and cause hair loss. The strong chemicals used in such treatments jeopardises the hair. One should take care to use products of branded and reputed companies to avoid hair fall.
Though not established scientifically, many believe that stress too causes hair loss. Any kind of mental trauma, worries and emotional strain leads to hair fall.
Hair loss can also be caused by a combination of the causes listed above. Loss of hair can be fought by treating the root cause of the problem. Once the cause has been identified, take the appropriate steps that will stop hair loss.
