Some people are born with Grey Hair which has been passed down genetically.
But whether the start of greying hair comes with aging or prematurely, it seems to be almost entirely based genetic.
Hair follicles contains pigment cells which produce a chemical called melanin.
It is this melanin that gives the growing shaft of hair its color.
But as we grow older in life, these pigment cells gradually die which results in less and less melanin over time that that will result in gray hair.
In some cases, Grey hair may be a deficiency of B12 or caused from a thyroid imbalance.
Although some people think that a traumatic experience in life may turn a persons hair gray, there is no evidence to support this.
