Did you know hair graying has a link with ethnicity? On an average, you’ll see African Americans graying in their 40s, Asians graying in their late 30s, and white-skinned people showing signs of graying as early as in their mid 30s. So if you are graying earlier than you should, it is premature graying.
Hair is naturally colored by a pigment called melanin, which is released by special cells called melanocytes. As you age, the hair shaft and your hair follicles begin to wear down. Over time, the number of melanocytes decreases or they cease to function as effectively as before – and that’s when you begin to see signs of “graying.” 1 But premature graying can have several causes and risk factors.
5 Causes Of Premature Graying
1. Genetic Tendency
The tendency for graying early can be coded in your DNA. And in a
2. Lack Of Certain Nutrients
Smoking can make you age faster, making hair go gray earlier than 30 years of age and causing skin to wrinkle.6 While the exact mechanism is not understood, scientists think it’s due to oxidative stress caused by the free radicals or reactive oxygen species nicotine releases.
4. Damage Caused By Free Radicals
Oxidative stress is an enemy for your melanocytes, whether brought about by radiation, emotional or psychological stress, or inflammation in the body. All of these generate free radicals.7
Even prolonged exposure to sunlight can cause your hair stress. Oxymelanin is an oxidative photo degradation product generated due to sunlight exposure, which causes stress to your hair strands and shaft.8
Over time, as the natural antioxidant levels in the body go down, hydrogen peroxide, a byproduct of metabolic reactions in the body, collects near the hair roots. Hydroxen peroxide is a bleaching agent. So it eventually leads to hair graying.
5. Certain Autoimmune And Genetic Disorders
If you have celiac disease or kwashiorkor, it leads to protein loss, which then affects the melanocytes.9
- Vitiligo, an autoimmune skin disorder 10
- Hashimoto’s disease and Grave’s disease, autoimmune thyroid disorders causing hypothyroidism and hyperthyroidism, respectively
- Werner syndrome, also called adult progeria
- Zinsser-Cole-Engman syndrome or dyskeratosis congenita, an inherited syndrome, which doesn’t just turn your
4 Ways To Prevent Hair Graying Prematurely
Normal age-related graying is to be expected, and you can’t really escape it, though some lifestyle changes can help prevent it from going gray sooner than normal. Certain foods like antioxidant-rich foods can also help slow the pace of natural aging of hair. What you could prevent, however, are triggers for early graying that are avoidable, or other causes that can be brought under control by treating underlying disorders. Some of these are given below.
1. Eat The Right Foods
Feed your hair the nutrients it needs and you may be able to slow down the graying of hair. Besides avoiding the deficiency of certain nutrients,
- Vitamin B12: Get adequate B12 by ensuring your diet contains eggs, shellfish, organ meat, poultry, and milk.14 But also check if you have low stomach acid, which makes absorbing vitamin B12 difficult.
- Vitamin D: To increase vitamin D levels, besides getting enough exposure to sunlight to help your body produce the vitamin, you can consume fatty fish like mackerel, tuna, or salmon, or eat beef liver, egg yolks, or cheese.15
- Copper: Consume dark leafy greens, potatoes, cocoa, yeast, black pepper, dried fruits, whole grains, shellfish, nuts, beans, and organ meat.16
- Iron: Have more green leafy
- Vitamin A is needed for oily sebum production, a natural conditioner for your hair that keeps it from going dry and brittle. It can be found in cod liver oil, eggs, orange/yellow fruit and vegetables like carrots, as well as dark leafy vegetables and broccoli.18
- Vitamin C which helps with collagen production needed for healthy hair growth is easily available in a variety of foods including citrus fruits, berries, brocolli, caulfilower, red/green peppers, spinach, tomatoes, sweet potatoes, potatoes, and more.19
- Vitamin E protects hair from sun damage from the inside out and can be found in nuts, vegetable oils, seeds, and green vegetables like spinach and broccoli.20
- Antioxidants like phenols, carotenoids, and anthocyanins which can be found foods and spices like onion, garlic, turmeric, pomegranate, blueberries, spinach, broccoli, and legumes
2. Protect Hair From Radiation
If you are in a workplace where you may be exposed to radiation, use adequate protection. If your hair is suffering due to simple sunlight exposure and UV radiation-related damage, then a hat or scarf to cover up your hair so it does not get exposed directly can be a simple fix.
3. Stop Smoking
While smoking can increase your risk of going gray early, you can reverse some of the damage before it is too late. As researchers discovered, smokers who stopped smoking were able to halt the increased pace of aging over time and bring it back to normal. This will impact graying as well, but must be done before it’s too late because hair that’s turned gray will stay that way.22 Here’s how you can stop.
4. Treat Hormonal Problems Naturally
Ayurveda has a range of remedies for treating hypothyroidism, or underactive thyroid. By addressing this endocrine problem, you could also help you bring back the balance of T3 and T4, the thyroid hormones that, among other things, modulate hair color.23
