White hair is linked with the aging process. However, it is depressing to detect it in your mid-thirties or early twenties. White and gray hair are the consequence of loss of hair pigments. Gray hair occurs when the hair pigment is significantly reduced. It becomes completely white when there is no pigment available. Unfortunately, the root cause of this condition is still unknown. In this article, we have listed a few options for preventing white hair growth. Keep reading.
What Causes White Hair?
Hair growth happens when old cells are pushed out by the hair follicles due to the production of new cells. It occurs in three stages – growth (anagen), cessation (catagen), and rest (telogen). During the rest period, your hair reaches its lifespan and falls out, and a new strand grows in its place. Hair color is produced by melanin, which is formed by melanocytes. Pigmentation in hair, unlike in skin, is not continuous. The hair is actively pigmented in the anagen phase. Pigmentation reduces in the catagen phase and is absent in the telogen phase (1). Casey Simmons, a curly hair expert, says, “Hair can change in color and shape as you age due to changes in skin cells and hormones.” She also adds, “Other health factors like thyroid issues, lack of iron, iodine, and vitamin B12 may also cause hair to gray.” With age, the amount of pigment that is injected into each strand of hair gets reduced, which is why it turns gray and eventually white. In the section below know how to stop white hair and factors causing white hair and how to prevent white hair. Early-onset of gray hair occurs due to the following factors:
1. Genes
Dr. K. Harish Kumar, MD, DVL, says, “Genes are the predominant factor in determining at what age your hair loses pigment.” For some people, it can happen even before they turn 20. For others, the first strands of white appear rather late (1).
2. Deficiency Of Melanin
In most of the cases, a deficiency of melanin is the leading cause of hair whitening. The production of melanin depends on appropriate nutrition and protein supplements. The lack of these nutrients causes melanin to fall below acceptable levels (2).
3. Hormones
Research suggests that an imbalance in hormones can trigger or increase premature graying of hair (1), (3). If you have excess graying of hair and aren’t sure if you have a hormonal imbalance, please consult a doctor.
4. Medical Conditions
Certain underlying medical conditions can trigger a loss of pigment in your hair. PGH is also triggered by autoimmune diseases like vitiligo, pernicious anemia, thyroid diseases, and premature aging syndromes (4).
5. Vitamin And Mineral Deficiency
Deficiency in iron, vitamin D, folate, vitamin B12, and selenium may also cause the whitening of hair follicles. Deficiencies of Vitamin B12 and folic acid with lower levels of biotin were found in people having premature graying of hair (5).
6. Stress
Emotional stress also plays a role here. Studies have shown that the oxidative load caused by psychological stress can trigger premature graying of hair (1).
7. Chemicals
Sometimes, the use of chemical-based shampoos, soaps, hair dyes, etc. may directly cause this problem. However, it can result from some allergic infections as well.
8. Oxidative Stress
Oxidative stress can cause premature graying. It is caused due to an overproduction of oxidants in the body, which are also affected by extrinsic factors like ultraviolet (UV) rays, pollution, emotional factors, or inflammatory causes (2).
9. Smoking
Studies have shown that smoking is one of the major factors leading to premature graying of hair. Smoking causes reactive oxygen species damage to hair follicle melanocytes, which leads to premature graying (1).
10. Hydrogen Peroxide
The hair follicles produce small amounts of hydrogen peroxide, which gets accumulated overtime on the hair shafts. It bleaches the hair and causes it to turn gray, and eventually white (6). Removing this build-up may help your hair regain its natural color.
Can You Get Rid Of White Hair?
Whether or not hair graying can be reversed to help white hair turn black largely depends on the cause of graying. If genetics are responsible, there is not much one can do to reverse the change. If the cause is an underlying health problem, consulting a doctor to see what can be done is the best course of action. Once the problem is treated, it may help restore pigment to your hair. However, this cannot be guaranteed. Re-pigmentation is sometimes possible after hormone therapy treatment. Another way to promote pigmentation is by taking shots or pills of vitamin B12. You can also try the natural remedies mentioned below and know how to reduce white hair.

Tips For Reducing Gray Hair
1. Increase Intake Of Vitamin B12
Your hair could be turning white due to a deficiency of vitamin B12 (5). If this is the case, reversing the graying process could be as simple as consuming sufficient amounts of the vitamin. Vitamin B12 deficiency causes pernicious anemia, and your hair losing its pigment is a symptom of the condition. This condition can be reversed by maintaining a balanced diet that is giving you the right amounts of the vitamin.
2. Increase Intake of Vitamin B5
Vitamin B5 is known to help prevent the early onset of graying hair and restore its natural color (20). It also aids hair growth, gives hair proper moisture, and has anti-inflammatory properties. Consume foods rich in vitamin B5 like mushrooms, beef liver, eggs, whole grains, broccoli, sunflower seeds, etc. (21).
3. Keep The Thyroid Levels In Check
Your thyroid gland has an impact on all the vital functions of your body. An underactive thyroid, or hypothyroidism, can result in premature white hair (3). It is necessary to monitor your thyroid levels to be aware if it is causing the loss of pigment in your hair. Hypothyroidism is a serious chronic condition and might require hormone supplementation. Certain foods can interfere with the working of your thyroid gland. To keep your thyroid levels in check, keep tabs on your diet.
4. Quit Smoking
Your lifestyle has a huge influence on the health and color of your hair. Smoking has adverse effects on your body and could be contributing to white hair (1). A study determined that smokers have a higher chance of their hair losing pigment than non-smokers (22).
5. Load Up On Antioxidants
Your diet may help prevent the occurrence of white hair. Make sure that you consume enough antioxidant-rich foods.
6. Protect Your Hair From UV Rays
One of the extrinsic factors of oxidative stress is UV rays, which lead to premature graying of hair. Make sure you protect your hair when going out in the sun with a scarf or hat. There are a number of heat protection products that protect hair follicles from the harmful sun rays.
7. Foods To Eat To Reduce White Hair
If you are graying due to a vitamin B12 deficiency, you should consume more seafood, eggs, and meat, including pork, beef, and lamb. Dairy products, such as milk and cheese, are good sources as well. Those following a vegetarian or vegan diet can opt for supplements or products that are enriched with vitamin B12 after consulting their doctor. Also, consume antioxidant-rich foods such as berries, grapes, green leafy vegetables, and green tea. Here’s a list of foods that can help aid hair growth and delay premature graying of hair (20):
Berries – They are rich in vitamin C. Meat liver – Combats anemia and iron deficiencies. Carrots – Rich in vitamin A. Curry leaves – Rich in the B vitamins and minerals such as selenium, iodine, zinc, and iron. Spinach – Helps in the production of melanin. Eggs – Rich in vitamin B12. Beans – Rich source of protein. Sunflower seeds – Rich in antioxidants and minerals. Walnuts – Rich source of copper, which helps in melanin production.
Can White Hair Turn Black Again?
Casey Simmons says, “The skin cell’s melanin is not known to typically have come back and increased in production, as they are naturally reducing from age and change in hormones.” A 2016 mice study targeted molecular pathways that control hair pigmentation to restore color. The mice exhibited growth of melanocytes that form melanin in the skin and hair. The discovery suggested that developing a drug or other therapy to target these pathways may help bring back some color to gray tresses (23). With the right diagnosis and treatments, graying can be reversed, and white hair can turn black. But if the problem is genetic or age-related, it is unlikely to reverse the process. It is possible, however, to slow it down with a balanced diet and a good hair care regimen. Can exercise prevent white hair? Casey Simmons, curly hair expert, says, “In theory, exercise promotes the overall health of the body, and, therefore, hair. However, it has not been scientifically proven to prevent gray hair. The main factor in hair going gray is a reduction in melanin, which has not been known to be affected by exercise.” Should I pluck white hair? You should never pluck your white or graying hair. Plucking out the hair causes trauma to the hair follicles, and repeated trauma may cause permanent damage. It may affect new hair growth and its texture and lead to infections, scars, or even bald patches. Which fruit is good for preventing white hair? The Indian gooseberry, also known as Amla, may promote pigmentation and reduce graying. Gooseberry is rich in antioxidants and has anti-aging properties. It is also used in many hair care products. Is white hair normal at 22? A few gray hair strands are normal during the early and late 20s. However, premature graying may indicate underlying conditions like nutrient deficiencies, hormonal imbalances, and other medical conditions.
