Despite the claims made online and by product marketers, it's not possible to reverse white hair if the cause is genetic. Once your hair follicles lose melanin, they can't produce it on their own. As melanin production slows, your hair turns gray, and then white when melanin production has completely stopped.
Can White Hair Turn Black Again? Genetic or age related greying of hair cannot be reversed. However, greying related to diet, pollution, bleaching and stress can be slowed down with a balanced diet and a good hair care regimen.
Kraleti doesn't recommend plucking or pulling the hairs out. “If there is a gray hair you must get rid of, very carefully cut it off. Plucking can traumatize the hair follicle, and repeated trauma to any follicle can cause infection, scar formation or possibly lead to bald patches.”
Though, ageing is the primary reason of grey hair but premature greying of hair in early 20's or 30's is now common. Genetic factors, stress, lack of nutrition, chemicals, smoking or any underlying disease like anemia can also lead to premature greying of hair.
The bottom line. While diet and an overall healthy lifestyle can help minimize gray hairs, there's only so much that you can do to control the natural loss of melanin in your hair follicles. There's also a significant genetic component to graying hair.
Deficiency in diet
For example, studies reveal that a lack of iron, copper, vitamin B, iodine, and omega 3 causes grey hair, which is why they must be included in the diet. On the other hand, packaged, junk, refined, or processed foods, might contribute to even more greying.
Eating foods rich in omega-3 fatty acids and zinc such as fish, seeds as well as leafy greens like kale and broccoli, can help in reversing the greying process.
Genetics
Your makeup plays a big role in when (or if) you develop white hair. If you notice white hair at an early age, it's likely that your parents or grandparents also had graying or white hair at an early age. You can't change genetics.
Eggs. Another food that may be causing your grey hairs to pop up eggs (but mostly raw ones). According to Science Direct, raw eggs can be the main cause of biotin deficiency, as they prevent one's GI system from absorbing biotin.
Egg white is the richest source of protein and in fact, eating one whole egg can help repair hair. Those with premature grey hair are low on vitamin-B12. Eggs can help replenish the lower levels of this vitamin. Boiled eggs are great for maintain and repairing hair health.
Sodium is important to ensure you have the right balance of fluids in the body. Over consumption of salt can cause grey hair, high blood pressure and chronic kidney disease.
Coconut oil helps retain the protein in the hair and prevent greying. Also, the oil has nourishing properties which is good for your hair. To use this oil for keeping whitening of hair at bay, you directly need to apply 2 tablespoons of virgin coconut oil to your scalp and hair.
What are the benefits of Onion Oil? Onion oil helps in promoting hair growth and using this on a regular basis also treats hair loss and premature baldness. It also fights dandruff, itchy scalp, and hair breakage. Apart from this, onion oil is beneficial for premature graying of hair.
Your environment is polluted
Pollutants and toxins can cause you to grey faster, according to the Library of Congress. These chemicals generate free radicals-or oxidative stress-that damage melanin production and speed hair aging, studies suggest. But once hair grows out of the follicle, it's dead, adds Dr.
In addition to being good for your scalp, coconut oil also moisturizes your hair. Since it's easily absorbed, it works better than other oils at repairing dry hair. Keep in mind that coconut oil alone may not be effective as a shampoo to cleanse hair, but as a pre-shampoo treatment, it will condition hair.
Vitamin or mineral deficiency — Any deficiencies of vitamin B-6, B-12, biotin, vitamin D, or vitamin E can contribute to prematurely going gray. Similarly, deficiencies in minerals like calcium, copper, iron, protein and zinc can also contribute to graying hair earlier than usual.
Amla oil is said to stimulate hair growth, as well as prevent hair loss and early graying. When used as a hair treatment, amla oil is applied to the head or face.
Premature graying may be reversed with vitamin B12 supplementation only if vitamin B12 deficiency is the cause. If you are graying due to other factors, such as genetics, zinc deficiency, medications, your gray hair cannot be reversed.
Mix 2-3 tsp of onion juice, 1 tsp of lemon juice and 1 tsp of olive oil. Massage into the scalp and hair and wash off after half an hour. An effective solution for greying hair, onion also promotes hair growth. It increases the enzyme, Catalase, thus darkening the hair.
Strengthens hair.
Aloe vera has many active ingredients and minerals that can help strengthen your hair. It has fatty acids and amino acids and is rich in vitamins A, B12, C, and E. These play a part in healthy hair follicles.
