At some stage in our lives, both men and women will experience the on set of gray Hair. Contrary to popular belief gray hair is not always related to ones age. Gray hair can occur as young as in our teens and range into our late 50’s and even older.
Everybody is different but the pigment of our hair is generated in the same way.
Initially, hair is white. The cells in our hair follicles called “Melanocytes” generate pigments the main one being Melanin. This gives our hair its “Color”.
In general, the more melanin present, the darker the hair color; the less melanin, the lighter the hair color.
When these Melanocytes stop producing the pigment the result is a transparent hair. The transparent hair against your healthier darker hair gives the appearance of Gray hair. In reality the hair is not Gray but transparent.

If your mom or dad started going Gray at a young age then the chances are you may also suffer from premature gray hair. This is not always the case. Age does play a large part in the graying process. The pigment in the hair shaft is generated from cells at the base of the root of the hair and as we get older these cells start producing less pigment until there is no pigment at all in the hair and we end up with the transparent hair. Harvard scientists proposed that a failure of melanocyte stem cells (MSC) to maintain the production of melanocytes could cause the graying of hair.
