Use of hair dye is extremely common worldwide. However, our literature search failed to find studies concerning the knowledge and attitudes of the public with regard to hair dyes. We sought to explore the knowledge and practices of, and attitudes towards, the use of hair dye among females.
A cross-sectional survey conducted on females who attended various outpatient clinics at King Khalid University Hospital in Riyadh, Saudi Arabia, a tertiary referral hospital open to the general public.
A self-administered questionnaire about the use of hair dyes was distributed randomly among females attending the outpatient clinics at a university hospital in 2008.
The response rate was 87.2%, with completion of 567 of the 650 distributed questionnaires. The mean (SD) age of respondents was 32.0 (10.2) years. Among respondents, 82.6% (464/562) had at some point dyed their hair. Furthermore, 69.3% (334/482) had dyed their hair in the past 12 months. The mean (SD) age of the participants when they first dyed their hair was 22.2 (7.1) years (range, 7-50). Of the participants, 76.8% (354/461) used permanent dyes, and about the same percentage of participants believed such dyes were the safest hair dye type. However, 52.4% (278/531) of the participants believed that hair dyes are harmful, and 36% (191/531) believed that hair dyes could cause cancer. Younger females tend to dye their hair less frequently (P<.001), whereas those with less education tend to dye their hair more frequently (P=.013).
Use of hair dye is very common among females. Because the practice starts at a very young age, we conclude that hair dyes are overused and misused. The public should be informed about the risks associated with excessive hair dye use.
染发在全球极为普遍。然而，我们的文献检索未能找到关于公众对染发剂的认知和态度的研究。我们试图探究女性使用染发剂的知识、行为及态度。
在沙特阿拉伯利雅得的哈立德国王大学医院进行的一项横断面调查，该医院是一家向公众开放的三级转诊医院，调查对象为在各门诊就诊的女性。
2008年，一份关于染发剂使用情况的自填式问卷被随机分发给在一所大学医院门诊就诊的女性。
应答率为87.2%，650份问卷中完成了567份。应答者的平均（标准差）年龄为32.0（10.2）岁。在应答者中，82.6%（464/562）曾在某个时候染过头发。此外，69.3%（334/482）在过去12个月内染过头发。参与者首次染发时的平均（标准差）年龄为22.2（7.1）岁（范围7 - 50岁）。在参与者中，76.8%（354/461）使用永久性染发剂，且大致相同比例的参与者认为此类染发剂是最安全的染发剂类型。然而，52.4%（278/531）的参与者认为染发剂有害，36%（191/531）认为染发剂可能致癌。年轻女性染发频率往往较低（P<0.001），而受教育程度较低的女性染发频率往往较高（P = 0.013）。
染发在女性中非常普遍。由于这种行为从很小的年龄就开始，我们得出染发剂存在过度使用和滥用的结论。应该告知公众过度使用染发剂相关的风险。
