When the body is undergoing stress due to physical or emotional circumstances, it has a great impact on our hair. We either start losing our hair or it starts to grow white. Any compromise in the nutrition and nourishment of the body can lead to hair loss. Serious illnesses that require strong medicines and radiation therapies can also cause hair loss. Another common cause for hair loss is the under activity of the thyroid gland. This usually causes the hair to become brittle and thin out because of wear and tear and other damage. Excessive exposure to the sun and chemicals like bleach, chlorine, and other dyes also lead to a lot of hair loss. Scalp infections caused by fungi can cause temporary loss of hair too.
In males, the androgenic hair loss, caused by hormones is quite common. This same problem has been seen in women too. Women do have male hormones, though less in volume and quantity. These hormones have important roles to play in the normal functioning of the body. With increased doses of estrogen, you might be able to counter the hair loss due to the male hormones. Another way to tackle this particular problem is by blocking the male hormones through a hormone replacement therapy.
With the physical causes, the emotional causes also have a great role to play in hair fall. Depression and anxiety have been noted as causes for severe hair loss. A lot of people have the habit of pulling at their hair when they are nervous or anxious. This can lead to a natural thinning of hair and can induce hair loss.
