Reversing Grey Hair

my hair began falling out the day  after a chemical accident. about a year ago. and my hair has been losing colour, “turning grey”.
i have done some reading and this is what i found ….

below are extracts from several articles.

Onion Juice For Hair: Benefits & How To Make

to read the full and original article, go to the source 
The use of onion juice for hair growth has become a popular trend for those seeking a remedy for unexplained hair loss. Onion juice, quite simply, is pressed from the onion plant, which comes in a variety of species in the Allium genus.

One of the most widely available vegetables in the world, onions contain a rich supply of vitamin C, various B-family vitamins, sulfur, calcium, iron, potassium, manganese, phosphorus, and magnesium, as well as other antioxidants, phenolic compounds, and anthocyanins. This dense nutrient profile can have a number of positive effects on the body, including for hair growth.

Benefits of Onion Juice for Hair Growth

The top benefits of using onion juice include its ability to moisturize the skin, improve follicle health, prevent infection, relieve inflammation, slow the graying of hair, and stimulate circulation.

Improves Circulation

The active ingredients in onions are known to increase circulation under the skin, which can drive important nutrients and oxygen to the hair follicles, thus stimulating hair growth and improving healing.

Reduces Inflammation

The antioxidants in onion juice make it ideal for soothing inflammation of the scalp, which can often lead to dry skin or impaired function of the hair follicles. By reducing this inflammation, you can cut down on dandruff and lower your chance of infection from open wounds.

Prevents Graying of Hair

Onions possess an antioxidant enzyme called catalase, the lack of which can lead to premature graying of the hair. Without this compound, hair becomes weaker and is more likely to fall once it changes color; the regular application of onion juice for hair growth can ensure this doesn’t happen.

Protects from Infection

Various fungal, bacterial or viral infections can affect the scalp and lead to hair loss, and also impede further hair growth. Onion juice has a number of antibacterial and anti-fungal properties that can protect against pathogens that may lower hair follicle function.

Moisturizes the Scalp

Onion juice has an invigorating and moisturizing effect on the scalp, which can help prevent dry skin and provide the hydration that hair follicles need to grow.

Improves Follicle Health

Onion juice is extremely dense in nutrients and minerals, many of which the hair require to grow, such as sulfuric compounds. Directly massaging onion juice into the scalp and hair can stimulate the growth of hair from unhealthy follicles and maintain normal growth from healthy follicles.

How to Make Onion Juice?

It is popular to make your own onion juice for hair growth at home, as it isn’t the most common vegetable juice on the market.


2 large yellow onions


  • Step 1 – Wash and peel the onions. Chop them into quarters or smaller chunks.
  • Step 2 – Add the onions to your blender and blend for 1-2 minutes.
  • Step 3 – Strain the onion juice through a sieve or cheesecloth.
  • Step 4 – Press the onion pulp to extract as much juice as possible.
  • Step 5 – Refrigerate the onion juice until you are ready to use it.

How to Use Onion Juice for Hair Growth?

Although most people consume vegetable juice for its many health benefits, you should topically apply onion juice for hair growth, as this is a more direct way of delivering the nutrients to the areas of your body that need it most.

  • Step 1 – Massage the onion juice into the scalp and any bald patches that may be appearing.
  • Step 2 – Leave the onion juice in your hair for 15-20 minutes.
  • Step 3 – Wash out the onion juice with warm water and a mild shampoo.
  • Step 4 – Repeat this process daily for best results.

Note: You may add honey to the onion juice to increase its efficacy and further enrich your hair follicles.

Side Effects of Onion Juice

There are some notable side effects of using onion juice for hair growth, including an itchy scalp, eczema, and even a burning sensation, as well as the potential for allergic reactions.

  • Itchiness and Burning: Due to the high sulfur content found in onion juice, it is known to create itchiness on the scalp, which can escalate to a burning sensation and excessive scratching. This can lead to more inflammation, open wounds that are ripe for infection, and an increase in dandruff and dry skin, none of which help symptoms of hair loss.
  • Eczema: Topical scalp eczema has been reported in people with sensitive skin who use onion juice for hair growth. Speak with a doctor before using this juice if you have sensitive skin on other parts of your body.
  • Allergic Reactions: Some people do have topical allergies to onions, and while most people are likely aware of these allergies, the concentrated nature of onion juice may have unexpected side effects, such as inflammation, hives, and rashes on the hands and scalp.

Has Science Cured Gray Hair?

to read the full and original article, go to the source 

A team of European researchers claims to have found not only the root cause of gray hair, but also a treatment for the condition. Additionally, their treatment may help people with vitiligo, a condition that causes the loss of pigment in patches of skin, they say.

It’s been known for years that hair turns gray due to a natural buildup of hydrogen peroxide in hair follicles, which causes oxidative stress and graying. (Hydrogen peroxide solutions have been used for years as a cheap and easy way to “go blonde.”)

In younger people, an enzyme called catalase breaks down hydrogen peroxide into water and oxygen. But lower levels of this enzyme, combined with lower levels of enzymes called MSR A and B that repair hydrogen peroxide damage, cause hair to turn gray as people age.

The researchers, whose findings are published in the experimental-biology publication FASEB Journal, analyzed 2,411 people with vitiligo.

By looking at people with two different kinds of vitiligo — strictly segmental vitiligo (SSV) and non-segmental vitiligo (NSV) — they discovered that both kinds resulted from oxidative stress.

And by applying a topical treatment, a substance called PC-KUS, the researchers successfully treated the discolored skin and eyelashes of people with vitiligo.

What Causes Grey Hair – Surprising Reasons You Didn’t Know

this is a brilliant article, go just directly there. to read the full and original article, go to the source

in fact the whole website is brilliant.
everything for hair. how to keep healthy hair.
this is what they say about onion, food sources of catalase and hydrogen peroxide.

An onion a day may help keep grey hair away. Onions are rich in antioxidant enzyme catalase, which restores the hair’s natural colour. Besides, the phyto-nutrients in onion along with their vitamin C, folic acid, and copper also help to delay greying of hair.

Eating onion is one way you can use its colour reversing power. But, you can also apply onion juice on your scalp to reduce the build-up of hydrogen peroxide and reverse grey hair. In fact, onion juice hair mask has been used since ancient time to remedy grey hair. It even helps with hair loss and makes your hair grow faster, softer and shinier.

How to use:
Just blend a small onion in a blender and strain the juice with a sieve or muslin cloth. Apply this juice to your scalp and let it sit for about 30 minutes, then wash as usual. Repeat twice a week.
You can also mix onion juice with equal amounts of coconut oil and follow above instructions.
And if onion smell is too strong for you, mix onion juice with 1 egg and 1 tablespoon olive oil and apply.

Eat foods rich in Catalase – a potent antioxidant that helps to prevent grey hair
New research suggests that it is not the loss of hair pigments that turns hair grey; it is the build-up of hydrogen peroxide in the hair follicles that literally bleaches the hair inside out.

Hydrogen peroxide is naturally produced in our bodies as a by-product of regular metabolism. It is also formed as a result of exposure to X-rays, second-hand smoke, stress, and pollution.

When we are young, our body produces a large amount of an enzyme called catalase – which is a powerful antioxidant. Catalase quickly breaks down the hydrogen peroxide molecule into harmless oxygen and water. But as we age, our bodies produce less catalase. Even factors such as stress and poor diet can cause catalase levels to go down. This causes the build-up of hydrogen peroxide in the hair follicles – which breaks down the hair pigments, as a result the hair turns white.

Foods rich in Catalase:
The good news is that several foods contain high levels of enzyme catalase. And eating them regularly will help return your natural hair colour back. Catalase rich foods include: almond, wheat grass, garlic, onion, leeks, cabbage, broccoli, kale, cucumber, collard, turnip greens, carrots, radish, cherry, potatoes, and sweet potato.

Premature Greying Syndromes

The aetiology of premature hair greying is not always known, but it can be symptomatic of underlying autoimmune disorders such as vitiligo, or endocrine disorders such as hypothyroidism (McDonough and Schwartz, 2012; Pandhi and Khanna, 2013). Genetic conditions affecting melanocyte biology, including Waardenburg Type II syndrome and Tietz syndrome (caused by mutations in MITF and SOX10), are also characterised in part by premature hair greying and, as with physiological hair greying, the greying is associated with a loss of melanocytes (Tassabehji et al., 1995). Premature hair greying also features in segmental progeroid syndromes, rare genetic syndromes of accelerated aging of multiple organs and tissues, including dyskeratosis congenital (which is caused by mutations in TERT), Hutchinson–Gilford progeria syndrome (which involves mutations in Lamin A/C) or syndromes caused by defective DNA repair, such as Werner syndrome, Cockayne syndrome or xeroderma pigmentosum (Sahin and Depinho, 2010). Environmental factors, such as UV light (Trueb, 2006), smoking (Mosley and Gibbs, 1996) and oxidative stress (Shi et al., 2014; Wood et al., 2009; Kamenisch and Berneburg, 2009) might also contribute to premature hair greying, possibly through an increase in intracellular reactive oxygen species. Nutritional deficiencies in trace elements (Fatemi Naieni et al., 2012), including vitamin D3 (Bhat et al., 2013), vitamin B12 (such as in pernicious anaemia) and copper (such as in Menkes disease) can also lead to hair greying. These conditions are thought to reflect deficiencies in the pigmentation pathway rather than loss of melanocytes, such that colour can be restored with nutritional supplementation (Heath and Sidbury, 2006).

How can one decrease Hydrogen Peroxide levels in the body?

December 8, 2015

I’ve read that as we age Hydrogen Peroxide levels in our bodies increase due to our body having a harder time keeping the levels low. It’s also said to be the main cause of hair turning grey… according to recent studies in Europe, as Hydrogen peroxide levels incresase in the hair follicles due to age it has a bleaching affect which turns hair grey and eventually white. I’m more interested in decreasing the levels in general and not just in my hair shaft as it seems to be healthier overall and was wondering if anyone knew how to do this or if it’s possible.

to read the full and original discussion, go to the source 

Taking “let’s reduce the levels of H2O2 in the body” from that study represents an extreme and inaccurate over-simplification of the biochemical processes that lead to its accumulation. This is really nothing to worry about. There is no specific thing you can do to prevent this. If you are concerned about aging the advice is the same it has always been: stay physically active, stay intellectually active, form strong social networks, get plenty of sleep, reduce stress, and eat healthfully.

I find this question interesting, but I will suggest that if there is a good answer, it will be found by exploring the mechanisms in the body that result in higher peroxide levels.

So you would need to study the mechanism for how and why the body produces peroxide. Then you would need to determine the exact cause of increased production in elderly people. Keep in mind, people start going gray at different ages and to different degrees. It is entirely possible that there are multiple different triggering mechanisms that lead to higher production.

So you would need to establish a pathology. Only after establishing that can you determine a good answer. Because if the reason the body has increased production of peroxide is rooted in protecting itself from something worse, then you would be harming your health if you disrupted production. But it would be okay to find a means to reduce the threat the body was responding to in order to discourage it from increasing production.

This is complicated by the fact that establishing a general pathology doesn’t necessarily say anything about your specific pathology. If there are multiple different factors contributing to this process, after determining what all those factors are AND some means to redress each one individually, you would then need to determine which ones specifically applied in your case. Then and only then could you determine an effective means to reduce peroxide production or avert increased production without shooting yourself in the foot in the process.

To add on to schroedinger’s excellent response, I want to be even clearer to say that even if hydrogen peroxide levels in the body do increase over time and are involved in the aging process, it remains very unclear what effect decreasing those levels would have and whether it would be good or not.

As an example, consider a few recent cases that I think are somewhat similar in primary care medicine.
– The case of postmenopausal estrogen therapy. This used to be much more widely recommended for women suffering from menopause symptoms, and it was thought that the estrogen also could protect against heart disease. The reasoning behind this was that pre-menopausal women do have decreased risk of heart disease compared to men, and some studies, including a large nurses’ health study, had shown beneficial effects for your heart if you took hormonal therapy. Then the Women’s Health Initiative, a gold standard, randomized placebo controlled trial showed that hormone replacement therapy’s risks, including an increased risk of heart attacks, exceeded its benefits. Therefore no one’s using hormone replacement therapy anymore, right? Nope. This article from the NYT delves into some of the thorny issues involved in studying a problem like this.
– The case of calcium supplements. It used to be widely believed that it was a good idea to take calcium supplements when you were older, due to concerns about osteoporosis. The same study that upended prevailing assumptions about HRT, the Women’s Health Initiative, showed no benefit to taking calcium supplements. In fact, women who take calcium supplements appear to actually have higher risk of heart attacks, and also of kidney stones.

Both of these issues have been studied heavily, far far more so than hydrogen peroxide levels have, which is further to say that there is really zero conclusion you can draw on what hydrogen peroxide levels in your body actually mean and whether having more or less of it is good or bad. Having high hydrogen peroxide levels in your body could make your hair cells produce less hydrogen peroxide for all we know. The study concludes that hair cells produce more hydrogen peroxide because of a lack of the enzyme catalase, which to me suggests that hydrogen peroxide levels in your body have nothing to do with the levels in your hair (it’s the presence or lack of the enzyme to break it down that matters).

I know you said that the hair issue isn’t really what’s troubling you, but the point is that stuff in your body is doing a lot of complex things, and it can be really hard to say whether a substance in your body is “good” or “bad.” For example, hydrogen peroxide is used by your body to fight infections. It’s also a messenger that helps to control gene expression. Maybe not something we should be messing with unless we really understand what messing with it is going to do.

How about the recent evidence showing that low cholesterol diets don’t translate to you having a low cholesterol? Further proof that trying to increase or reduce levels of something in your body for a health outcome is not as straightforward as “eat more or less of X” or “eat more of something else that ought to reduce X.”

I’m thoroughly on board with the recommendation that in general if you want to be healthier, exercise and trying to get more plants into your diet are some of the best places to start (and quitting smoking and sugar if those are habits of yours)…. these are some of the general health recommendations that have the strongest evidence backing them for the human race as a whole.
