In cooperation with German experts, Several scientists from the University of Bradford believe that they finally solved a mystery that has been confusing millions of people: why our hair turns gray with age.

The researchers came up with their results by examining native hair and cells from human hair follicles（毛囊）. They say the secret turns out to be hidden in catalase（过氧化氢酶）, which is causing hair to turn gray.

Catalase production goes down with age and stress, allowing hydrogen peroxide（过氧化氢） in the hair to do its favorite job—making hair gray, and then white, by blocking the normal production of melanin（黑色素）. Melanin is our hair's natural pigment that is responsible for the color of hair. It also determines the color of our eyes and skin.

Dr. Gerald Weizmann, an editor of a journal, says," All of our hair cells make a tiny bit of hydrogen peroxide, but as we get older, this little bit becomes quite a lot, and our hair turns gray and then white."

The new study brings hope for millions of people who have to color their hair: to finally obtain some shampoo that will decrease levels of hydrogen peroxide and therefore restore gray or white hair to its natural color or even prevent it from turning gray.

The researchers are already conducting an experiment with such a drug on a few volunteers with gray hair and expect to get the results in the next two to three months. If everything works out, millions of people will choose between this drug and other previously used expensive dyes. However, even if the drug works, it will take at least several years before it can be brought to the market.

Wherever in the world you’re reading this right now, you will be aware of just how mixed modern society has become in terms of race. Within the UK, mixed-raced children are the largest 1 ethnic minority. Bringing home a partner of a different 2 to yourself is no longer viewed as, “strange” or “different” in a lot of families. When Joseph brought home Hari, the 3 that she was of Indian parentage was never even talked about — she made him happy. They made each other happy. And that was all that 4.

But the reason why they were together for 11 years before they got 5 is that Hari was afraid of telling her 6 about the person that she’d fallen in love with. She was afraid of the consequences it would 7 for her younger sisters. Would they be packed off to India? Would they end up in arranged 8 they may not want? At 22 years old, when she first fell in love with him — it was a large burden to 9.

But she loved him, and 10 they moved in together… and then bought a house by the Brighton coast, where they have 11 for almost 8 years. All the while her parents didn’t know. Her sisters did, and they too loved Joseph — they 12 him as the brother they’d never had.

But after nine years together, she finally had to tell her father (her mother 13 away a few years ago). We were on tenderhooks（惶恐不安）the weekend she went up North to tell him.

It was emotional and as a family we were worried. Hari had been 14 of our family for so long, we felt for her. We knew how 15 it would be. She loved her father, but knew this would hurt him, who was a very traditional Sikh man.
