Using specialised scanning and lab techniques, a team of researchers at New York University Langone Health examined how cells age in mice whose fur colour is dictated by the same cells. To determine the cause of grey hair.
The inability of pigment-producing cells to increase may be the cause of greying hair as people age.
Melanocytes, which are cells that contribute to hair growth and give hair its unique colour, are where it all starts. Its colour is black to Africans.
Grey hairs might start to show up fairly young.
Melanocytes can change and have an impact on the skin and hair. Stem cells, which are utilised to produce new ones, are thought to become “stuck” in limbo in persons whose hair has greyed.
Melanocytes might become worn out from working long hours. When hair ages, sheds, and continually regrows, many melanocytes stem cells lose effectiveness.
The follicle’s stem cells stop circling and settle down, failing to differentiate into fully formed melanocytes. In the absence of colour, the hair turns silver, white, or grey.
They contend that the study could lay the groundwork for reversing the greying process and treating other illnesses.
