Bald spot on head
Hair adds visual appeal to one’s physical appearance. The average lifespan for a healthy strand of hair is between 2 and 5 years. When a strand of hair falls out, a new one automatically replaces the old strand and begins its life. The hair normally grows one and a half inches per month. All of these factors describe a normal strand of hair. However, there are several people all over the world who are experiencing problems related to baldness. There are several reasons bald spots can develop on the head. The problem can be cured with surgery or medications; there are also a number of natural therapies and remedies that have proven to be effective.
The Main Cause of Bald Spots
Bald spots can occur for both genders, but the problem is more common in men than women. There are many reasons for this. Fortunately, it is possible to resume hair growth if the cause of the problem are identified. Here are some of the reasons balding may occur.
Genetics is the main reason for balding. This can happen with men and women. For instance, if both your grandfather and father were bald, chances are you will also experience baldness. This is known as pattern baldness.
Additional Reasons for Balding
Aside from genetics, here are a few more reasons why a person could lose their hair.
- Androgenic alopecia. This is a major cause of baldness. The condition occurs when testosterone is converted to dihydrotestosterone. Androgenic alopecia can happen with both women and men. Women may develop a bald spot due to high androgen levels in pregnancy; using birth control pills, menopause, perimenopause, or polycystic ovarian syndrom leads to androgenic alopecia as well.
- Stress and shock. These are also contributing factors to baldness. Surgery and illness could also be the reasons for hair loss. Mental and psychological stress can cause the hair to fall out as well. However, trauma to the body and stress are only causes of temporary baldness, as the hair usually grows back after the body is no longer under stress.
- Medication. Baldness is the side effect of some medications. Thyroid medication, as well as antidepressants, chemotherapy and radiation can cause a person to lose his/her hair. This is temporary and will reverse itself after the person is no longer taking the medication that is causing baldness.
- Poor nutrition. A deficiency in iron, zinc, protein, vitamins and minerals can cause the hair to fall out. A drastic change in diet can lead to baldness as well. People who experience hair loss due to poor nutrition often have thinning hair and bald spots at various areas on the head.
- Alopecia areata. This is an autoimmune disease in which the immune system attacks the hair follicles, causing bald spots. The body may heal itself to eliminate the condition, or an individual with alopecia areata can receive treatments to restore hair growth.
Certain infections, like ringworm, can also prompt the hair to fall out. Ringworm is a common fungal infection that is highly contagious. The bald spots caused by ringworm tend to be round and are accompanied by itching, blisters and redness. Yeast infections and bacterial infections lead to hair loss as well. Diabetes, lupus, Addison’s disease, or an over- or underactive thyroid can also lead to hair loss in both men and women.
