What Determines Baldness

The hair care industry brings in millions of dollars in revenue annually from both men and women. Unfortunately, for some individuals, hair care becomes a source of frustration as hair loss begins and advances into baldness. It is important to understand what factors determine baldness if the baldness (and the resultant frustration) is to be treated.


Genes


Probably the most common determinant of baldness is genetic makeup. Genes are related to testosterone and estrogen production. A combination of genes is responsible for transforming regular testosterone into a potent form of testosterone, dihydrotestosterone, which is related to the shrinking and lack of regeneration of hair follicles. Conversely, estrogen production encourages hair growth on the scalp. However, both men and women can carry the genes related to baldness, so one cannot necessarily determine the genetic predisposition for baldness by looking at only one gender or side of a person's family.


Hormones








Hormones are second to genetic influences in determining hair loss and baldness, because hormones are related to the production and health of hair follicles. Women commonly experience hair loss after pregnancy, because estrogen levels drop significantly, for instance, and thyroid conditions result in imbalances that affect hair regeneration.


Disease








Some diseases are related to baldness or hair loss. This is because disease robs the body of the ability to concentrate on and have the energy for healthy hair production, and because the diseases have an effect on hormone levels within the body related to hair growth. An example of a disease that affects baldness is diabetes.


Surgery/Medication


Not all baldness is permanent. In these cases, the effects of surgery or medication could result in baldness. Medications that are particularly connected to hair loss are chemotherapy drugs. When the person recovers from the surgery or ceases the medication, the body usually begins to grow hair again.


Age


Age is the final determinant of baldness. As one ages, the rate of follicular regeneration decreases. The less often a follicle regenerates, the more likely the hair will fall out. As a result, elderly individuals typically see a thinning of their hair or go bald as they get older.


Considerations


With the advancement of science, new methods of hair loss treatment are being made possible. These include follicular transplants, drug therapy and dietary supplementation. This means that one does not need to settle for hair that is too thin or does not grow.
