A research completed in August 2016 but published on 14 February 2017, conducted at the University of Edinburgh by the Department of Cognitive Ageing and Cognitive epidemiology and published by the University of Bonn in Germany on PLOS Genetics, shows how, on a sample of 52000 men, 287 DNA sequences were identified to indicate the susceptibility to hair loss.
Genetics and Baldness: How are they related?
Baldness affects about 80% of men before the age of 80 and has psychological and social consequences related to the awareness of the problem and the perception of the society around us. Previous studies have shown that hair loss is early and not, in addition to altering the physiognomy of an individual, it has negative health effects and dedicated studies have associated with baldness an increased risk of prostate cancer and cardiovascular problems in addition to the fact that the problem can be due to hereditary factors.
For these reasons, it is advisable not to underestimate baldness and carry out specialist texts with tricologi experts to prevent and control, through targeted treatments, any problems of hair loss.
The Research of the University of Edinburgh
Prior to this study only a handful of chromosomes had been identified as “those responsible for hair loss”, but thanks to the data collected by the UK Biobank related to 52874 male people with an average age of 57 years it was possible to make a formula that tries to predict the possibilities of a person to become bald, in relation to the presence/absence of certain genetic markers.
Although the development of an infallible exam is still at the beginning thanks to this study it is possible to identify macro groups of people who have a higher risk of baldness than the average.
In detail, taking a look at the data provided by researchers in relation to the identified genetic patterns, we can discover the reliability of these new information as among all the subjects with fewer genetic factors among the 287 identified only 14% were Calvi while 39% still had hair as in youth. In contrast, in men with a higher number of genetic factors attributable to baldness (among the more than 280 detected), almost 58% had lost their hair.
Results of this search
Of this interesting research the first given that is reported by the researcher Saskia Hagenaars is that the several hundreds of genes highlighted as “guilty” are all related to the X chromosome, that is, the one inherited from the maternal figure and not from the paternal figure.
Further information on the study is provided to us by Dr David Hill, also the research team, and is related to the fact that in this study the collected data are related to a recurrent pattern related to hair loss but not related to the date of start of the fall.
In conclusion, the research coordinator, Dr Riccardo Marioni of the Department of Genetics and Experimental Medicine of the University of Edinburgh, it explains to us that the team is looking for a method to make accurate predictions in relation to the pattern of hair loss in humans and that these results mark a fundamental step in the research on baldness because they will open new ways to better understand the genetic causes of hair loss , but that is still too early to achieve a reliable DNA test at 100%.
Waiting for an infallible integrated test prevention is the best solution to avoid hair problems: thanks to a thorough check-up it is possible to understand the remedies necessary for the different problems in order to act in a timely manner before the onset of baldness.
