Why Does Hair Turn Grey?
We’ve all dreaded that first strand of grey hair. And if you’ve assumed that old age would bring about those salt and pepper strands, you are in for a huge shock. Many people grey out at different ages. While most witness their first grey strand in their mid thirties, there are quite a few too who can go grey in their twenties. It makes one wonder, what exactly is this science behind grey hair.
When these melanocytes cells stop producing or lessens the production of melanin, it affects the colour of the hair and turns it grey. So grey hair basically depends on ones “melanocytes clock”.
As we age this melanin production gradually decreases and that’s why grey hair is associated with growing old. But other than that there are several internal and external factors that affect grey hair.
