Whether you like it or not, it's normal for your hair color to turn gray as you age.

Of course, there are many people who embrace and love their natural gray hair. Moreover, many young women are big fans of the 'granny' hair trend and dye their hair gray on purpose.

And if you're like me, you're not fond of gray hair. Even a few gray strands can annoy you. You think having gray hair makes you look old and unattractive.

Well, whether you're someone who flaunts their gray strands or someone who is bothered even by a couple of them, there's one fact that no one can deny: Going gray is inevitable.

What Causes Hair To Whiten?

We have thousands of hair follicles in the skin's epidermis on our heads. A hair follicle is a structure that regulates the growth of the hair, and as it ages, it produces less color as it loses pigment cells.

Although your genes determine when you start graying to a certain extent, you're more likely to go gray after you turn 30.

What Determines When Your Hair Begins To Turn White

  • Genetics

Some people can go gray before turning 20, whereas others can spot the first gray strands later.

  • Melanin Deficiency

Inadequate nutrition and lack of protein supplements lower melanin production, which, in turn, leads to hair whitening.

  • Medical Conditions

Vitamin B-12 deficiency, thyroid disorders, and some autoimmune diseases may cause premature graying of hair.

  • Stress

Along with an increased intake of processed foods and alcohol, stress increases a person's risk of going prematurely gray.

  • Hormones

Hormonal imbalance can lead to hair whitening.

  • Extrinsic factors

Air pollution, climate, and exposure to harmful chemicals can cause your hair to lose pigment early.

Gray Hair Prevention

If you have noticed a few gray hairs here and there, don't worry. You can make your natural hair color last longer by making specific changes to your lifestyle and eating habits. These changes include:

  • Stop Smoking

Smoking adversely affects your health in many ways, and in addition to this, smoking damages your hair follicles.

  • Increase Your Intake Of Minerals

The following minerals play an important role in promoting hair growth and strengthening your hair:

  1. Iron
  2. Zinc
  3. Selenium
  4. Magnesium
  5. Copper
  • Increase Your Intake Of Vitamins

To keep your hair healthy and shiny, get enough of the following vitamins:

  1. Vitamin D
  2. B vitamins, particularly biotin and B-12
  3. Vitamin A
  4. Vitamin E
  • Stop Damaging Your Hair

Not only do the following actions damage your hair, but they also lead to premature graying of hair:

  • Using harsh shampoos which contain a large number of sulfates, formaldehyde, parabens, and synthetic colors and fragrances
  • Strengthening, curling, or blow-drying your hair too frequently
  • Bleaching your hair
  • Often exposing your hair to the sun
  • Brushing your hair instead of combing it using a wide-toothed comb
  • Often washing your hair
  • Consume Foods That Help Prevent Loss Of Pigmentation

Such foods include:

  1. Berries
  2. Eggs
  3. Shellfish
  4. Spinach
  5. Walnuts
  6. Sunflower seeds
  • Practice Yoga

Believe it or not, practicing some yoga asanas can help prevent white hair formation. These yoga asanas include:

  • Chakrasana
  • Uttanasana
  • Kandharasana
  • Sarvangasana
  • Trikonasana

Natural Home Remedies For Gray Hair

Some home remedies can help stop or prevent hair whitening. These include:

  • Amla (Phyllanthus Emblica). Apply amla oil to your scalp once a week or drink 170 milliliters of amla juice every day.
  • Ginger (Zingiber officinale). Mix one teaspoon of grated ginger with one tablespoon of honey and consume the mixture every day.
  • Black sesame seeds (Sesamum indicum). Consume one tablespoon of black sesame seeds at least three times a week in order to reverse or prevent white hair progression.
  • Coconut oil. Massage your scalp and hair with coconut oil, preferably before going to bed. Then, rinse your hair with warm water.
  • Apply ghee to your scalp and hair two times a week.
  • Wheatgrass (Thinopyrum intermedium). Add a tablespoon of wheatgrass powder to your smoothies, stews, or soups every day, or drink 30-60 milliliters of wheatgrass juice daily.
  • Carrot juice. Drink 240 milliliters of fresh carrot juice regularly.
  • Onion (Allium cepa). Put one onion in a blender and then strain the onion to separate the juice from the onion pieces. Massage your scalp with the juice two times a week.
  • Curry leaves (Murraya koenigii). Put ½ cup of yogurt, and ¼ cup of curry leaves in a blender and blend until smooth. Apply the paste to your scalp and hair and leave it in place for half an hour. Do this at least three times a week.
  • Antioxidant-rich food. Oxidative stress enhances the loss of pigmentation and encourages hair whitening. Consuming foods high in antioxidants decreases the process of reducing melanin.

Foods loaded with antioxidants include:

  • Dark chocolate
  • Blueberries
  • Pecans
  • Artichokes
  • Strawberries
  • Raspberries
  • Goji berries
  • Red cabbage
  • Kale
  • Black tea. Due to the tannic acid found in black tea, this tea can pigment your hair and help it restore its natural color over time. Apply black tea to your hair once or twice a week.

Catalase is an enzyme that helps reverse the graying process.

Consume foods loaded with catalase, such as:

  • Cabbage
  • Broccoli
  • Garlic
  • Pineapple
  • Kiwi
  • Sweet potato
  • Almonds
  • Kale
  • Almond paste. Accumulation of hydrogen peroxide can lead to white hair formation. Applying almond paste can help prevent the buildup of this chemical compound. To make almond paste, put ground almonds, 1 egg white, one teaspoon of almond extract, and some honey and water in a food processor and pulse until consistently mixed. Apply the paste to your hair once a week.
  • Sesame. Sesame helps stimulate melanocyte activity, which, in turn, promotes melanin production. So, consume sesame regularly to prevent the occurrence of white hair.
