Here’s why you are getting bald

PLOS Genetics published a new study which focuses on the reason behind baldness in males. Researchers from University of Edinburgh studies 52,000 men and identified 287 genes related to baldness, in UK.

Men between the age of 40 and 69 years were analysed, where their genomic and health data were noted. According to the data, 32 percent reported no loss in hair, 23 percent had slight hair loss and rest 27 percent were suffering from severe hair loss, so much so that they were either on the verge of baldness or were already bald.

Single-nucleotide polymorphisms, or SNPs are the most common type of genetic variation among people, it was found to be linked with baldness. With this information scientists have developed a DNA-based algorithm.

As many genetic variations are located on their X-chromosome, it was concluded that men inherit it from their mothers. The sex chromosome interacts with the hair protein, it interferes with its work, resulting in hair loss and greying of hair earlier than it should be.

Riccardo Marioni Ph.D., of the University of Edinburgh’s Centre for Genomic and Experimental Medicine and the lead author of the study said “We are still a long way from making an accurate prediction for an individual’s hair loss pattern. However, these results take us one step closer. The findings pave the way for an improved understanding of the genetic causes of hair loss”.

It was known that this factor comes from mother’s side but the extent to which it affects has been understood only after the study.

The study did not recorded the ages of men, as on what age they started losing their hair. They might get a better understanding in the filed if they also look at the age factor. The additional information will perhaps give a clear view of the group that is more likely to go bald.
