Premature greying of hair is a common problem in youngsters these days. In general, white or grey hair is taken as an old age symbol, but this might be very embarrassing to get them in your late 20’s or early 30’s.
There can be various causes for premature greying of hair. It can be due to malnutrition or genetic reasons. In this article, we’ll be discussing some of the most common causes of premature grey hair and natural ways to treat them.
What causes premature greying of hair?
The greying of hair is a natural and inevitable process. It is said to be normal if you have a few grey hairs when you are in your 40’s.
As a teenager, it can be due to genetic reasons or improper nutrition from your diet. Human hair can be of different colors like brown, red, black, or grey. Pigmentation is the reason behind the natural coloring of your hair. 
Human hair consists of a pigment called melanin. Melanocytes, a neural crest-derived cell (located in the bottom layer of the skin’s epidermis) is responsible for the production of melanin.
Your hair follicles reduce forming melanin with your age, which causes hair to turn grey or silver. You’ll be left with all white hair when melanin formation is completely stopped. 
Reasons behind early age greying of hair
Premature greying of hair is always related to your genetics. It is often seen that parents who have got their hair of wisdom at an early age; their children are more likely to get it at an early age too.
There are mainly two factors- intrinsic and extrinsic, which work in the greying of hair. Genetics are related to intrinsic factors of premature greying of hair.
Extrinsic factors include malnutrition, hair damage due to various toxic chemicals, smoking, specific medical conditions, and excessive sun exposure.
Insufficient melanin production:
Hair gets its color from a pigment called melanin. The cell that produces melanin (Melanocytes) due to various reasons gets damaged and stops melanin production, causing greying of hair.
Regular and long term smoking:
Smoking is very toxic for every organ of the human body. Smoking indirectly also contributes to grey hair.
Smoking can lead to oxygen deficiency in your skin and may increase free radicals, ultimately affecting your hair by accelerating stress and aging of the follicles. 
Too much exposure to the sun:
The UVA and UVB rays from the sun can damage your scalp, further producing premature grey hair.
Chemicals used in hair styling products:
Various chemicals used in hair styling products can cause great damage to your hair. Hairstyling gel, shampoo, and even hair spray come with dangerous ingredients in them, which negatively impact melanin formation.
Stress or trauma:
Stress is also a leading reason for premature greying of hair. Stress causes an increase in cortisol, aka “the stress hormone,” which can accelerate the follicle’s aging. 
If you are suffering from anemia, then you might be facing premature grey hair problems. In anemia, your body lacks the healthy red blood cells to carry out oxygen to different organs. This reduction of oxygen in hair follicle ultimately reduces the melanin formation, which starts greying of hair.
Deficiency of vitamin B12 and vitamin D can cause premature greying of hair. Vitamin D is required for the absorption of calcium in the body. Not only for calcium, but it is also very much essential for melanin production.
Folic acid deficiency:
Folic acid helps in cell growth, metabolic, and DNA functions. Folic acid deficiency can affect follicle, which may lead to premature greying of hair.
Can grey hair be reversed?
The answer to this question is not that simple. Grey hair can be or can not be revered to its original color. It depends on what causes the grey hair to appear for you.
In a recent study by Columbia University researchers , it is found that grey hair due to stress and trauma can be revert back to your original hair color. According to the report, hair can be turned grey when they lack the protein that provides nutrition to them. People with less psychological stress can be seen with less grey hair than people with much stress.
Adopting a healthy lifestyle and including a nutrition-rich diet can help to deal with premature greying of hair. There are many natural remedies in Ayurveda, which you can try to relieve yourself from this untimely wisdom of yours.
