Issue: An unexpected bald patch of hair 意想不到的秃顶
You may have Alopecia Areata, which occurs when your immune system starts attacking the hair bulbs. It doesn't destroy it, but the bulb won't start to grow again until the attack is called off. According to the National Alopecia Areata Foundation, it affects five million people in the U.S. "It could be stress or it could be environmental factors -- we really don't know," Dr. Mirmirani says. It can happen one time or recur with some frequency. If you find a sudden bald spot, see your dermatologist.
当免疫系统开始攻击毛球，你可能出现秃发现象。免疫系统并没有摧毁它，但是毛球在攻击停止之前不会再生长了。根据全国秃发基金会的数据显示，秃发影响到在美国的500万人。马诺莫尼医生说：“至今我们不知道确切的原因，这可能是压力或者环境因素造成的。”秃发可能发生一次也可能以一定的频率发生。头发还能变黑因为这不是永久性的损坏。如果发现突然性的秃发，请去找皮肤科医生。
