The Connection Between Height And Hair Loss
It has been well known for quite some time that men tend to lose their hair as they grow older, with some becoming completely bald. But additional research carried out by the University of Bonn has found that there also appears to be a relationship between height and hair loss. More details on these studies are provided below.
How The Research Was Done
Genetic material was taken from a group of over 22,000 men from multiple countries all over the world. Assessing the genetic samples revealed more than sixty different changes for DNA which is capable of increasing the possibility of developing premature baldness. Specifically, this research found four key areas within the DNA that showed a strong correlation between the hair loss in the men and their height.
Men who are short have a much greater chance of developing MPB (Male Pattern Baldness) than those who are of average height or taller than normal. This study is considered to be the largest to be conducted on the phenomenon to date. It draws data from 8 association studies which are genome wide and independent. Over 10,800 subjects who have premature baldness were analyzed, with another 11.600+ men who do not suffer from hair loss. But MPB is not merely linked to men that are shorter; there are also a number of other factors at play.
Additional Factors That Contribute To Hair Loss
Additional things which influenced male pattern baldness, aside from height are lower body size, reaching puberty earlier and a number of cancers. In particular, those who are at greatest risk of developing prostate cancer have also been found to suffer from male baldness. But another major factor that contributes to this issue is testosterone.
Testosterone is a male hormone responsible for growth, which can be transformed into dihydrotestosterone or DHT, which is another type of androgen. DHT is known for producing and spreading prostate cells, which is perfectly normal in teenagers as it contributes to their growth and development but in middle aged men will cause BHP, or benign prostatic hyperplasia, which is better known as an enlarged prostate.
MPB Is Not Trait Which Is Isolated
The data from the studies provides another revelation, that rather than being a trait which is isolated, male pattern baldness shares a considerable biological basis with many other phenotypes that exist among men. These traits are fascinating to researchers as it sheds more light on the evolutionary factors which have led to high cases of MPB among certain groups of men, namely Europeans. White males tend to have a greater likelihood of becoming bald than non-White men.
A connection has also been found between skin color and greater density within the bones. This could possibly mean that those men who experience hair loss had a greater ability to utilize sunlight in a manner that could provide vitamin D synthesis, which would explain White males losing their hair at a greater rate than non-White males.
