Recently, the phrase "hair loss" has been trending among young people in China. A recent report on overall health showed that hair loss ranked fifth among top health concerns, following bad skin conditions, depression and anxiety, poor sleep, and digestive tract(消化道)discomfort and illness.
But hair loss isn't just a concern for Chinese youth. It is an inconvenient reality for many people in China and the world over. According to a survey, 250 million Chinese people are troubled by hair loss, most of them between 20 and 40 years old. In the United States, about one in five people is suffering from hair loss.
There isn't really any single reason for hair loss. Humans naturally lose about 50 to 100 hairs each day, which usually regrow later. However, genetic and environmental factors can mean, for some people, these lost hairs won't regrow. In addition, certain factors can further worsen hair loss, including too much stress from work school, too little sleep, and a bad diet.
Is there anything you can do to protect your remaining hair? There are many products out there ready to help you keep a full head of hair. Shampoos, lotions, surgery, even laser-helmets say they can help. Hair loss treatments represent a $3. 6 billion industry in the United States alone. While many of these products make bold promises about their capabilities to restore your hair, the reality is that fixing your hair loss will ultimately depend on finding the specific causes.
If it is due to stress, lack of sleep, or poor nutrition, then a lifestyle change might not only stop hair loss, but also restart the growth of hair. For most young people who want to protect their receding(后移的)hairlines, it starts with their personal health. All they need to do is change unhealthy living habits and pay more attention to their psychological well-being.

My father died when I was nine, and I remember doing the household chores(杂务)to help my mother. I hated changing the vacuum cleaner(真空吸尘器)bag and picking up things the machine did not suck up.
Twenty years later, in 1978, I was doing chores at home alongside my wife. One day the vacuum cleaner was screaming away, and I had to empty the bag because I could not find a replacement for it. With this lifelong hatred of the way the machine worked. I decided to make a bagless vacuum cleaner.
Easier said than done, of course. I didn't realize that I would spend the next five years perfecting my design, a process that resulted in 5,127 different prototypes(设计原型). By the time I made my 15th prototype, my third child was born. By 2,627, my wife and I were really counting our pennies. By 3,727, my wife was giving art lessons for some extra cash, and we were getting further and further into debt. These were tough times, but each failure brought me closer to solving the problem.
I just had a passion for the vacuum cleaner as a product, but I never thought of going into a business with it. In the early 1980s, I started trying to get licensing agreements for my technology. The reality was very different, however. The major vacuum makers had built a business model based on the profits from bags and filters(滤网).
No one would license my idea, not because it was a bad one, but because it was bad for business.
That gave me the courage to keep going. Then, in 1993, when my bank manager personally persuaded Lloyds Bank to lend me $1 million, I was able to go into production. Within two years, the Dyson vacuum cleaner became a best-seller in Britain.
Today, I still embrace risk and the potential for failure as part of the process. Nothing beats the excitement of invention. Go out and brainstorm your ideas. You are not bound to any rules—in fact, the stranger and riskier your idea, the better.

Dear Leo,
Know that you are in low spirits for the quarrels with your parents，I would like to help you, but I can totally understand your feelings.
To start with it, you should know what this kind of communication problem worries nearly all the teenagers. Therefore, you don’t have to blame yourself not having a good relationship with your parents.
Actually, it isn't easy for them to talk about myself with my parents either, so my solve is to write down my thoughts in a letter to them. We need to tell them what we want and learn to negotiate. For example, I once get my parents to let me hang out with my friends on weekends unless I got better scores.
What’s more, trust the love of your parents for you and have some faith in them.
They will absolute listen to you and understand you in the end.
I’m looking forward to your good news.
Yours,
Li Hua
