What Your Gray Hair Says about You

Gray hair, according to new findings, is caused by a massive build up of hydrogen peroxide due to wear and tear on hair follicles. The peroxide winds up blocking the normal synthesis of melanin, your hair’s natural pigment.

All hair cells make a tiny bit of hydrogen peroxide, but as you age, the amount increases. Essentially, you bleach our hair pigment from within, and your hair turns gray and then white.

Researchers made this discovery by examining cell cultures of human hair follicles. They found that the build up of hydrogen peroxide was caused by a reduction of an enzyme that breaks up hydrogen peroxide into water and oxygen.

They also discovered that hair follicles could not repair the damage caused by the hydrogen peroxide because of low levels of the enzymes MSR A and B, which normally serve this function. The high levels of hydrogen peroxide and low levels of these enzymes also disrupt the formation of tyrosinase, another enzyme that leads to the production of melanin in hair follicles.

Experts Uncover Cause of Greyness

Scientists at Bradford University believe they have uncovered the root cause of why hair turns grey.
……………………………….
Experts found grey hair was caused by a build-up of hydrogen peroxide

.

It is an accepted part of the ageing process, but experts say understanding how grey hair happens could help find a way to prevent it.

Experiments found it is caused by a massive build-up of hydrogen peroxide due to wear and tear of hair follicles, which blocks hair’s natural pigment.

The research has been hailed as a “major breakthrough”.

The scientists worked in collaboration with experts in Mainz and Luebeck in Germany and the discoveries have been published in the FASEB scientific journal, published by the Federation of the American Societies for Experimental Biology.

Lead researcher Karin Schallreuter said experts examined hair as well as cells from human hair follicles to uncover the findings.

He said: “This discovery is a major breakthrough in the understanding of hair greying and opens up some novel ideas to combat this scenario.

“These are being followed up at the current time in our laboratory.”

Going gray? Hair ‘Bleaches Itself as People Age’

[amazon_link asins=’B00SG595J8,B01M7ZQQ3G,B0013U0EYI,B0035LCWB6,B000FZXGB0,B000Q384SQ,B018MGA4KE,B001FXSQHK,B073RHHZHF’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’531ee2eb-e875-11e7-a1b0-bd02baf6fa09′]

Why people turn gray is no longer a gray area, for scientists have finally solved the mystery by discovering that hair bleaches itself as  people age.

A team in Europe has found that going gray is caused by a massive build up of hydrogen peroxide due to wear and tear of our hair follicles. The peroxide winds up blocking the normal synthesis of melanin, our hair’s natural pigment.

According to Gerald Weissmann, the Editor-in-Chief of the ‘FASEB Journal‘, which published the study, “All of our hair cells make a tiny bit of hydrogen peroxide, but as we get older, this little bit becomes a lot.

“We bleach our hair pigment from within, and our hair turns gray and then white. This research, however, is an important first step to get at the root of the problem, so to speak.”

In fact, the scientists made this discovery by examining cell cultures of human hair follicles. They found the build up of hydrogen peroxide was caused by a reduction of an enzyme that breaks up hydrogen peroxide into water and oxygen (catalase).

They also discovered that hair follicles could not repair the damage caused by the hydrogen peroxide because of low levels of enzymes that normally serve this function (MSR A and B).

Keeping & Maintaining Beautiful Hair

[amazon_link asins=’B01MY9HU0D,B06WW7T9PL,B01FIDJYQ4,B01E9GO19G,B00Q1SSF5W,B01E83XHFY’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’0cc2e5a2-c559-11e7-9669-77fcf503b6f1′]

Three main things are needed for a good-looking head of hair – haute hair – good health, the right attention to cleanliness, and caution when using cosmetic treatments.

CLICK & SEE

1. Adequate Diet
Hair growth depends on an adequate diet. A widespread diet problem which causes loss of hair is iron deficiency Anaemia. The cause is too little iron in blood, brought on by a diet containing too little meat, eggs, cereals or peas and beans. Fresh fruits and vegetables are also needed to provide vitamin C, which enables the body to absorb iron.

2. Cutting the hair
Although cutting the hair is not essential to its well-being, it is easier to keep the scalp clean if the hair is kept reasonably short. Regular cutting does not make the hair grow strong or faster.

3. How hair can be damaged
Although scalp hair is hardy, and can withstand a lot of abuse, it can be damaged by too much or inexpertly applied perming, dyeing – Blonde to Brunette, bleaching and massage. The amount of beautying the hair can take varies from person to person. Occasionally the scalp is allergic to the dye and becomes inflamed and swollen. To prevent this occuring, the dye should be tested by applying it to a small area on the arm. If a patch of inflammation has developed, the dye must not be used on the hair.

Most people who bleach their hair do so with hydrogen peroxide. If the peroxide is repeatedly applied, it may make the hair brittle. Hair SOS If this happens the hair may turn rough, develop split ends, or become thinned or shortened.

Now, How to Maintain Good Hair?
Maintaining your hair is very easy. But in order to have sleek, beautiful hair you must be quite dedicated. These few steps will enhance your entire look immensely.

1. Brush hair regularly to loosen dead skin cells and help brush out old hair styling creams/sprays. This also stimulates the scalp and helps to promote healthy hair growth.

2.Wash hair with good-quality shampoo and conditioner chosen specifically for your hair type. (The most gentle you can find for your hair, as this will prevent over-drying.)

3. Towel-dry hair, squeezing hair between the towel. Do NOT rub the hair, this can weaken the follicle and make the hair brittle and dull. The cuticle of the hair will not lie flat, so it will not be smooth or shiny.

4.A “tiny” amount of olive oil or a similar oil can be used to give hair shine and to condition it. Beware of going overboard — too much will make hair look like an oil slick.

5. Get a haircut to suit your face shape. If in doubt as to what would suit you best, ask your hairdresser.

6.Frizz-control serum can be used in small quantities to tame frizzies, but make sure you do not use too much, and wash once a week with a deep-cleanse shampoo to avoid build-up which will leave hair looking dull and flaky.

7.Once a week, massage hair and scalp with coconut oil, wrap in gladwrap or a showercap, and leave overnight. In the morning, rinse well with water, and shampoo and condition as normal.

8.If you have dry hair, massage your head with your scalp nightly, for 5 minutes. This, like brushing, stimulates the oil glands to produce the amounts of natural serum needed to have glossy, moisturised hair.

9.Don’t wash your hair too often, for this will dry out your hair.

10. Putting too much heat in your hair can cause damage to the hair shaft and hair.

11. When brushing or combing hair, be gentle. Combing too roughly will cause your hair to break off each time you brush or comb.

12. Use some type of hair conditioner or oil creames to your hair, this will avoid dullness and dry looking hair.

13. Give yourself a hot oil treatment at leasts twice a month to maintain healthy shiny hair.

14.When blowdrying your hair, put a oil or cream in it before you blow your hair to prevent the damages from the heat of the blow dryer onto your hair.

CARE FOR THE FOLLOWING:-
1. Straightening and blowdrying your hair too often can damage your hair, so make sure you use a heat protectant spray first.
2.Also, try to have days off (eg, on the weekend) where you do not heat-style your hair. Use a ceramic straightner when possible.
3.If you have coloured hair, put hair wax in it before swimming in chlorinated water or the sea. This will prevent it drying out too much, and from fading.

4.Try to give your hair a break a few times a week, and do not heat-style. Instead, experiment with up-dos — a simple ponytail or chignon looks clean and requires very few hair products. You could also just keep your hair down and wear a headband.

Three Green Beauty Alternatives

[amazon_link asins=’B0104O4ZZM,B0103UPJDY,B0104NFUKC,B001I83RHG,B015ORL3B8,B00DGJM37U,B01N3VNYEO,B006R76WK2,B0738J8NL9′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’da6f98c7-d9c9-11e7-a0ea-c1b368f6972f’]

You can go “green” with beauty products by lessening your use of the ones that use harmful ingredients. Here are a couple of organic beauty alternatives:


No-Hair-Washing : You don’t need to shampoo your hair every day. In fact, when you aren’t torturing your hair with product, it produces a natural oil that gives it a unique sheen and softness, and according to studies, it might even reduce the amount of ozone you breathe in.

Natural Deodorant : Store-bought deodorants and anti-perspirants contain harsh chemicals. Instead, try baking soda. Sprinkle a bit on a damp washcloth and apply it on your underarms; it should neutralize the smell and keep you cool all day!

Homemade Facials: Honey, oatmeal, bananas and other household materials can make you a homemade facial treatment!
