头发一项调查表明,女性如果一年染发次数超过12次,患淋巴瘤的概率会比从不染发的女性高26%。而且,染发剂颜色越深越危险。用黑色染发剂超过25年的女性,患病的风险比其他人高一倍。因此,每年染发不要超过两次,染发前一定要做皮肤测试。即将怀孕或已怀孕的女性都不宜染发。 A survey of hair shows that women who have more than 12 hair dyes a year have a 26% higher risk of developing lymphoma than women who do not. And, the darker the hair dye is, the more dangerous it is. Women who use black hair dyes for more than 25 years are twice as likely to be ill as others. Therefore, not more than twice a year, hair dyeing, hair must be done before the skin test. Women who are about to become pregnant or who are pregnant are not suitable for coloring.
