Some of the causes of gray hair have nothing to do with your genes.
Gray hair occurs to all of us at some point. But, why do some people go gray in their 20’s while others don’t see the first sign of gray hair until age 50?
The premature hair gray is nothing but a process where the pigment is not being produced from the cells which produce color.
Graying of hair is a natural process and as we age the ability to synthesize the normal amount of melanin pigment (responsible for giving black color to the hair) declines this ultimately results in gray or whitening of hair.
However, if the hairs gray earlier in life i.e. premature graying is connected to some pathologies and bad habits.
Here are 4 main reasons why your hair is turning gray earlier than expected.
1.A medical condition
In rare cases, premature graying may be triggered by health issues like thyroid disease or problems with the pituitary glands.
Moreover, autoimmune diseases that attack the hair, such as alopecia areata or vitiligo, can also cause gray hair. As the National Alopecia Areata Foundation (NAAF) explains, people with the condition develop small, round, smooth patches on the scalp, and they can completely lose hair on their head or body.
This happens because your immune system attacks your hair follicles, making your hair fall out. When it grows back, it grows back white.
According to dermatologists, smoking is one of the worst things you can do for your skin and hair. You may not be able to see wrinkles on the scalp but it’s still affecting all the (hair) follicles.
One reason is that smoking is the source of development of free radicals in the body of the smoker and these free radicals cause oxidative stress in the body, leading to decrease in the pigmenting capacity of the melanin and resulting in graying of hairs.
Some research has revealed a relationship between stress and gray hair. In a study conducted at the New York University, and published in the journal Nature Medicine, scientists observed the diminution of hair follicles via stem cell reduction in mice placed under stressful conditions.
According to scientists, if going gray is in your genes, stress can make your hair turn gray faster and earlier unless you make an effort to manage stress.
4.A vitamin deficiency
Vitamin and minerals, especially vitamin B12, zinc, and copper are responsible for the proper nourishment of the hair that assists metabolic processes involved in giving hair its natural color and deficiency of these vitamins and minerals affects the hair color.
If the body is suffering from the lacks of vitamin C and E, then the hair turns into gray very normally. The people who are highly addicted to junk foods rather than the nutritious (vitamin C and E) will lose their nice and silky black hair at a very young age.
Vegetarians and vegans, due to their dietary restrictions, may also be at a greater risk for premature graying. Individuals that take birth control pills and those with gastrointestinal or digestive issues may also be at a higher risk for premature graying.
