It may come as a surprise, but some components of your hair are related to your tooth enamel. As a result, a recent study found a link between hair disorders and the susceptibility to dental caries, the decay of teeth commonly referred to as cavities.
Hair and teeth share common developmental mechanisms. Of course, the major components of hair and teeth are very different both in appearance and structure.
However, there are minute components of tooth enamel that are also found in certain elements of hair. Researchers discovered that, as a result, when certain defects are found in a person's hair, there also tends to be a susceptibility to cavities.
Of course, treatment of your hair isn't going to fix that susceptibility to cavities. The relationship between the two parts runs much deeper and earlier in a human's development.
The study was presented at the General Session and Exhibition of the International Association for Dental Research.
