不论男女，有些人，到了年龄就会开始谢顶。这个现实着实让人难以接受，所以人们大多都愿意尝试防止秃头的药物疗法。据说，世界上的确存在能“治愈”脱发的良方，但这些办法真的管用吗？现代科学能否提供更有效的疗法？“秃头”对人有什么好处吗？本集《随身英语》讨论“秃头”人士的烦恼。 课文内容 Vocabulary: hair and baldness 词汇: 头发与秃顶 For many it means nothing at all, but to others it is the epitome of their identity. As humans, our appearance is often important to us and our hair plays a huge role. Whether you have long flowing locks or a swept back do, the way you wear your hair can say something about you. But what if you start to lose it? Forty per cent of men experience hair loss by the age of 35, according to the Belgravia Centre UK, one of Europe's largest hair loss treatment centres. This figure rises to 80% by the age of 80. And women are far from exempt from losing clumps of hair, with 50% of them suffering some form of hair loss in their life. It starts with a receding hairline, followed by a thinning of hair on the crown of the head and temples and before you know it, your scalp is showing and you're completely bald. Every human naturally loses between 50 and 100 hairs a day, according to the UK National Health Service. Excluding hair loss caused by disease, baldness is genetic. It's related to the hormone testosterone, which causes a shrinking of hair follicles in susceptible adults. This results in the loss of so called 'terminal' adult hair and the production of much finer 'vellus' hairs – like those on the heads of babies. |
