What causes grey hair? Can it be prevented or treated? 

One of the results of a lockdown during the current COVID-19 pandemic was that all hair parlours were closed down and those of us, why rely on their hair being dyed by professional hair stylists, were confronted with their grey hair again. 
Which made me want to uncover the various reasons why people get grey hair (in my case it was mostly B12-deficiency and stress) and whether grey hair can be prevented and/or treated. 

Hair gets its colour from a type of pigment called melanin. The formation of melanin begins in the fetus. Hair gets two types of pigments: the dark pigments are called eumelanin, and light pigments are called pheomelanin. These two types of melanin pigments blend together to form different types of hair colour. Again, these pigments are positioned properly in the hair follicles. So, when hair starts growing, these pigments are absorbed in the hair to give it a particular colour.

Hair colouration is a systematized process. So, if there is a slight difference in the bodily system, the hair loses its colour which is then called as grey hair. Over the decades, the researchers are working hard to find a real solution for grey hair. Unfortunately, there is no specific remedy yet come out that can provide the ultimate solution against grey hair. On the other hand, people must have a clear understanding on why they get grey hair. It will help them to find out the reasons specific to grey hair. Here are some of the causes of grey hair:

How do you recognize vitamin B deficiency?

Traditional media often run stories about how supplements may cause problems. One of the problems with studies highlighting supplements is they typically use synthetic vitamins, and not whole food supplements. Your body was not made to process unnatural agents, often posing as equivalents to the real thing. The reality is they are frequently not the same and do not provide you with the same health benefits.

Vitamin deficiencies may lead to illness and disease, and contribute to chronic issues such as high blood pressure, dementia and cancer. One nutritional deficiency having the potential to wreak havoc on your health, your cognition and even your respiratory system is a deficiency in vitamin B complex. B vitamins also help your body to detoxify from chronic exposure to pollutants and chemicals.

What happens in the citric acid cycle and why is it critically important for all life?

The Citric Acid Cycle, also known as the Krebs Cycle, is an important series of biochemical reactions that are intrinsic to cellular respiration and the generation of energy from oxygen and glucose in aerobic organisms. Although humans can generate energy anaerobically, they cannot do so for long periods and oxygen is essential for life because it fuels the Citric Acid Cycle. Without this cycle, there would be no available energy to maintain our vital processes.
