1. Issue: Excessive hair shedding 脱发严重
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.
每根头发都有它自己的生长周期，生长6-8年后，停止生长几个月，然后脱落。马诺莫尼说：“百分之十左右的头发会在任何一个特定的时间脱落。”她指出，压力、发烧、体重减轻或缺铁等因素都会打断头发的生长周期，并使更多的头发提早脱落。如果你发现头发脱落比平时更多，检查一下自己的生活方式，看看发生了什么改变或者咨询一下皮肤科医生。
2. Issue: Hair that is dry and has lost its luster 头发干燥并失去光泽
"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.
马诺莫尼医生说：“当头发角质层开始破坏，内部纤维暴露的时候，头发就会变得干燥。”过度加热将导致这种情况发生，尤其是对湿发加热。她建议在用电吹风吹干头发之前，先采用自然风干，并且使用日常护发素。请记住，毛纤维的颜色更容易损坏，所以染发的时候要格外小心。
3. Issue: Brittle or easily breaking hair 头发变脆容易断裂
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.
马诺莫尼医生指出，有些发型实际上会影响到你发球的健康。她看到许多人日复一日地拉伸头发或者把马尾绑得太紧。她说：“想想看，如果你一直拉植物的根部，那么植物最终将被损坏。”向后拉头发的时候手要放松，头发湿的时候不要用力地梳头发，使用宽齿梳子轻轻地梳。效仿玛莎·布雷迪为了头发亮泽，一天梳头100次？马诺莫尼医生说这样是不对的。梳得越少越好。
