Your hair follicles produce less color as they age, so when hair goes through its natural cycle of dying and being regenerated, it's more likely to grow in as gray beginning after age 35. Genetics can play a role in when this starts.
Vitamin B-12 deficiency is one of the most common causes of prematurely graying hair. Researchers have noted that vitamin B-12 deficiencies are often concurrent with folic acid and biotin deficiencies in people whose hair has started to turn gray early.
As we get older, the pigment cells in our hair follicles gradually die. When there are fewer pigment cells in a hair follicle, that strand of hair will no longer contain as much melanin and will become a more transparent color — like gray, silver, or white — as it grows.
One can reduce gray hair by:
Consuming sufficient amounts of vitamins and minerals (e.g., B vitamins, vitamin C, vitamin D, vitamin A, copper and zinc). Eating healthy: eat lots of vegetables, fruits, nuts, white meat, and fatty fish. Minimize consumption of red meat and milk.
Vitamin B-12 is the most common culprit, with folate, copper, and iron deficiencies increasing your risk, too. Dietary supplements may help these deficiencies and you might see your natural hair color start to grow back after several weeks.
Some studies have demonstrated that grey and ageing hair can recover its original colour when nourished by diets rich in zinc and supplements formulated with this element.
A new study shows that stress really can give you gray hair. Researchers found that the body's fight-or-flight response plays a key role in turning hair gray. Your hair color is determined by pigment-producing cells called melanocytes.
Grey hair and genetics
The average age for grey hair varies greatly, and one of the main causes of grey hair in your 20s is genetics. The age at which a person's hair turns grey is influenced by the IRF4 gene, and one specific variant (rs12203592) is a marker for premature greying.
Gray hair is one of the universal signs of advanced age. More likely than not, at some point in your life, your hair will start to go gray. Some individuals can maintain hair color well into their older age, but most do not.
Although the primary cause of premature hair graying (PHG) is considered to be genetic, certain environmental factors also play a role. Trace element deficiencies such as Vitamin B12, Vitamin D3, and calcium may also be associated with PHG.
There are no treatments that are proven to treat (or reverse) gray hair. As researchers learn more about how the graying process happens, they may develop effective medications and treatments for gray hair.
Does lack of sleep send my hair grey or white? Lack of sleep can have a negative effect on many aspects of the body, not only can it lead to tiredness and lack of concentration, but longer term effects such as your immune system and stress. Stress has been proven to cause grey hair as mentioned above.
Most people start noticing their first gray hairs in their 30s—although some may find them in their late 20s.
After studying information in 69 different publications about hair aging between different races and ethnicities, a group of doctors and scholars found that the average age of hair-graying onset varies according to race: Caucasians: Occurs in mid-30s. Asians: Occurs in late 30s. Africans: Occurs in mid-40s.
It can be inherited from either parent. The color of our hair is determined by the form of hair pigment that we have. The pigment is actually produced along the hair shaft, and there are two main forms of hair pigment. There's eumelanin and pheomelanin.
Aside from the time investment of a salon session, there's how long it takes to fully transition to gray hair, which is anywhere from six months to a year, Ferrara says.
Vitamins B6 and B12 have also been proven to boost melanin production. Goddard says that vitamin B6, also known as pyridoxine, has been found to trigger the production of enzymes and chemical reactions that boost the metabolism of the hair proteins (keratin and melanin) in the hair follicles.
The pigment in our hair is caused by melanin— the same pigment that is also responsible for our skin color. Gray hair is caused by a loss in melanin, whereas white hair does not have any melanin at all. As you age, your hair produces less and less melanin that leads your hair to appear gray, and then eventually white.
POSSIBLE ETIOPATHOGENESIS OF GRAYING
Reversible hypopigmentation of the hair can be seen in nutritional deficiencies protein-energy malnutrition and diseases of chronic loss of protein. Copper and iron deficiency also can cause graying of hair.
Biotin has many benefits. It triggers hair growth, it treats hair loss related disorders, and it thickens and strengthens the hair. One of our favorite beneficial effects of Biotin is that is can reverse premature greying of hair.
Melanin deficiency is associated with vitamin deficiency. That's why you need to increase your vitamin intake through your food or vitamin supplements. Vitamin A, C and B12 are the most needed vitamins to increase the melanin production in your hair.
Since baking soda is a scrubbing agent, washing your hair with it can gradually strip the dye from your locks. Baking soda can lighten all hair colors, but it might take a few washes to get your hair to the desired color.
