DNA contains the information that our body needs to carry out its vital functions, the set of biochemical reactions that is called “metabolism”. Scientific studies have clearly shown that all individuals are the same for 99.9% of their genetic makeup, so the 0.1% difference in their DNA determines the diversity we see between people. <\/p> \n \n
This diversity does not only concern the outward appearance, but causes each individual to respond in a unique way to environmental stimuli: each of us in fact has a different susceptibility to diseases, responds differently to food and, of course, has a different risk. to lose hair or develop trichological problems.<\/p> \n \n
This is because genetic differences between individuals can lead to modifications in the structure of genes and the proteins they encode, which is reflected in a modification of their activity.<\/p> \n \n
Does 0.1% seem low to you?<\/p> \n \n
The two people in the photo differ from each other by 0.1% of their DNA, therefore of the genetic information that underlies the functioning of their organism.<\/p> \n \n
However, we must keep in mind that we are not merely the result of what is written in our DNA<\/a>, but rather the result of the interaction between our DNA and our environment\u2014including our lifestyle, diet, and so on.<\/p>
\n
\n So knowing the information that derives from our DNA allows us to understand which are the “weak points” of our metabolism and to intervene in a targeted manner to keep our body in the best condition, blocking or slowing down those mechanisms that can cause the appearance of disorders and diseases, including hair problems.<\/p>
\n Androgenetic alopecia, commonly known as baldness, is linked to the effect of androgens on the hair follicle and depends on an individual\u2019s genetic susceptibility. In men, the onset of androgenetic alopecia is characterized by increased levels of the hormone dihydrotestosterone (DHT), which is derived from the conversion of testosterone by the enzyme 5-alpha reductase. Compared to men, in women the activity of the enzyme aromatase\u2014which converts androgens into estrogens\u2014plays an important role. These hormones have an effect opposite to that of DHT, inhibiting its production and counteracting hair loss. <\/p>
\n
\n Genetic testing is therefore used to identify individuals at risk for whom preventive treatment<\/a> is important to prevent the onset of baldness.<\/p>
