Why is my hair turning grey?

Our hair follicles contain color-producing pigment cells called melanocytes. These melanocytes produce melanin, the pigment which gives our hair its color. As we grow older, these melanocytes gradually die. With fewer cells in a hair follicle, the strand of hair belonging to this follicle will have lesser melanin. The strand becomes transparent, taking on a silver, grey, or white color as it grows. You might even notice that the tip of a strand of long hair has color, while the same strand is white at the root.

Younger people turn grey because of various factors. According to research, genes could play a role in premature greying. So, if premature greying runs in your family, you could also have premature grey hair.

Vitamin B-12 deficiency or a problem with your thyroid or pituitary glands could also cause premature greying. In these cases, melanocyte stem cells are not lost, and this premature greying can be prevented if the problem is treated in time. 

Some studies suggest that stress too can trigger premature greying.

Some foods like oranges, raw eggs, alcohol, and nicotine gum also cause premature greying.

Smoking, chemicals in hair products and dyes, certain medical conditions, and real-life stressors promote greying.

How to prevent grey hair

You can expect your hair to turn grey depending on your ethnicity. For example, if you are Caucasian, your will start turning grey in your mid-30s. If you are Asian, you can expect greys in your late 30s; if you are black, you can expect them in your mid-40s.

No matter what anyone tells you, greying is permanent because melanocyte stem cells are indeed lost, and it is impossible to regenerate pigment. However, there are several measures you can take to prevent prematurely greying:

  • Treat any vitamin deficiencies. Vitamins A, C, B6, and B12 are especially critical to boost melanin production and prevent premature greying. Vitamin B6 triggers the production of enzymes that boost melanin and keratin metabolism in hair follicles.
  • Eat healthily. Antioxidant-rich foods are the best. Foods like green leafy vegetables, vitamin C-rich foods, berries, dark chocolate, dairy products, soybeans, lentils, and even fermented foods can all ensure your hair does not grey prematurely.

  • Quit smoking if you want your hair to retain its radiant natural color.
  • Natural remedies like curry leaves, ridge gourd, Indian gooseberry, and black tea can help prevent greying naturally and safely.

Why is onion juice a great solution for hair turning grey

One of the reasons hair turns grey is the collection of hydrogen peroxide in the hair follicles. This hydrogen peroxide causes oxidative stress and greying. As the amount of hydrogen peroxide increases, there is a decrease in the amount of natural catalase.

Onions contain catalase - the antioxidant enzyme that reduces hydrogen peroxide in the hair follicles and prevents greying. Onions are rich in this enzyme - more catalase means the faster hydrogen peroxide breaks down in hair follicles. With less hydrogen peroxide, there is less damage to the melanocytes. Many believe that catalase can even restore hair’s original color.

How to make onion oil without smell

First, it’s important to clarify that the onion oil referred to here is not onion seed oil or onion essential oil. It is a unique formula prepared from onion bulbs.

Using onion oil on the scalp to prevent greying is a fantastic option, but onions are known to have a powerful smell, and onion oil prepared at home can smell pungent. Thankfully, there is a way to make onion oil that does not reek of the pungency of raw onions.

  • Strain the oil mixture.
  • Add a couple of drops of essential oil to mask the smell of onions.
  • Store the extracted oil in a non-metallic container.

How to use onion oil

You can use onion oil as a hot oil treatment or without heating it. Mix onion oil with a carrier oil such as olive oil for hot oil treatment. Heat it gently until it is lukewarm. Massage the oil into the lengths of your hair and your scalp. Let it stay on overnight, and wash it off with shampoo followed by a conditioner.

To use onion oil without heating, massage a little oil between your palms and then massage it into your scalp for about 15 minutes. Use circular motions to get the oil into your scalp. Leave the oil for a couple of hours before washing it with shampoo. Use it twice a week.
