1. Issue: Excessive hair shedding 脫發嚴重
Each individual strand of hair has its own cycle, growing for six to eight years, resting for a few months, and then shedding. "About 10 percent of your hair is shedding at any one given time," Mirmirani says, pointing out that many things can interrupt the cycle and cause more hairs to shed earlier, including stress, fever, weight loss or low iron levels. If you're noticing more shedding than usual, examine your lifestyle to see what might have changed or consult your dermatologist for tests.
每根頭發都有它自己的生長周期，生長6-8年后，停止生長幾個月，然后脫落。馬諾莫尼說：“百分之十左右的頭發會在任何一個特定的時間脫落。”她指出，壓力、發燒、體重減輕或缺鐵等因素都會打斷頭發的生長周期，并使更多的頭發提早脫落。如果你發現頭發脫落比平時更多，檢查一下自己的生活方式，看看發生了什么改變或者咨詢一下皮膚科醫生。
2. Issue: Hair that is dry and has lost its luster 頭發干燥并失去光澤
"Hair becomes dry when the cuticle starts to break down and the inner fiber is exposed," Dr. Mirmirani says. Excessive heat can cause this--especially heat applied to wet hair. She recommends air-drying your hair partially before blow drying, and using a daily conditioner. Remember that hair fiber with color is more prone to damage, so be extra cautious if you color-treat your hair.
馬諾莫尼醫生說：“當頭發角質層開始破壞，內部纖維暴露的時候，頭發就會變得干燥。”過度加熱將導致這種情況發生，尤其是對濕發加熱。她建議在用電吹風吹干頭發之前，先采用自然風干，并且使用日常護發素。請記住，毛纖維的顏色更容易損壞，所以染發的時候要格外小心。
3. Issue: Brittle or easily breaking hair 頭發變脆容易斷裂
Some hairstyles can actually affect the health of your hair's bulb, Dr. Mirmirani says. She sees this a lot with hair extensions or ponytails pulled too tight, day after day. "Think of it this way, if you keep pulling on the bulb of a plant, eventually, you can damage it," she says. Take it easy when you're pulling your hair back, and don't brush your hair vigorously when wet. Use a wide-tooth comb and comb through gently. As for Marsha Brady's 100 strokes a day for shine? Not so much, Mirmirani says. The less brushing, the better.
馬諾莫尼醫生指出，有些發型實際上會影響到你發球的健康。她看到許多人日復一日地拉伸頭發或者把馬尾綁得太緊。她說：“想想看，如果你一直拉植物的根部，那么植物最終將被損壞。”向后拉頭發的時候手要放松，頭發濕的時候不要用力地梳頭發，使用寬齒梳子輕輕地梳。效仿瑪莎·布雷迪為了頭發亮澤，一天梳頭100次？馬諾莫尼醫生說這樣是不對的。梳得越少越好。
