Contrary to the beliefs of some, the hair on our bodies is not permanent but undergoing a constant cycle of growth, shedding, and regrowth. Both our hair and our fingernails are made up of a substance called keratin. Hair grows from follicles that are located in the second layer of our skin, the layer called the dermis. After the hair is done actively growing, the follicle which holds it disintegrates, which causes the hair to fall out.
After that, a new follicle appears and the whole cycle starts over. The hairs on your head are replaced every two to five years, while eyebrow hair is replaced every four months. Alopecia is a condition that involves hair loss- this condition is also commonly known as baldness.
The hair undergoes a similar cycle for women too. But the hair-fall pattern is not similar to that of men. For men, the hair starts falling at the temples and gradually proceeds to the top of the head, leaving a tuft of hair at the sides and back of the head.
This kind of alopecia is commonly attributed to gensadasdasetics. But, illness can also be the culprit.
If hair loss is caused by an illness, the hair often grows back after the illness is cured. Chemotherapy and radiation treatments associated with some cancers cause baldness in both genders. Hair growth usually resumes once the treatments are finished. Other diseases, especially bacterial infections and illnesses like lupus, planus, and thyroid conditions can also cause hair loss.
Sometimes a person’s hair won’t fall out in a neat pattern. Instead it will randomly fall out in clumps throughout the scalp, resulting in bald patches. Their eyebrows and eyelashes may also shed. This type of hair loss is referred to as alopecia areata. While the medical profession has not come up with a cause for this disease, it is largely believed to be an autoimmune condition.
In most of these cases, the hair grows back within a year. The baldness can be cured by several methods. Oral pills, corticosteroid injections and creams containing corticosteroid drugs are the various treatments available to treat baldness. These treatments cannot cure everyone undergoing them.
Baldness is not a serious condition in that it does not cause physical discomfort or harm. But, baldness can definitely be harmful to one’s emotional health. Especially when there is little that one can do to stop it from affecting them. With all the treatments which are available, some might find it easier to use false hair/hair replacement items, such as a wig or hairpiece, until the baldness has run its course.
