7 Issue: An unexpected bald patch of hair 意想不到的禿頂

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.
當免疫系統開始攻擊毛球，你可能出現禿發現象。免疫系統并沒有摧毀它，但是毛球在攻擊停止之前不會再生長了。根據全國禿發基金會的數據顯示，禿發影響到在美國的500萬人。馬諾莫尼醫生說：“至今我們不知道確切的原因，這可能是壓力或者環境因素造成的。”禿發可能發生一次也可能以一定的頻率發生。頭發還能變黑因為這不是永久性的損壞。如果發現突然性的禿發，請去找皮膚科醫生。
