Abstract

CONTEXT

Hair plays an important role in one's personality and builds confidence. Now-a-days, chemical hair relaxers are used very commonly in the society. We document the adverse effects reported by the sample that have used any one of the professional chemical hair relaxers.

AIM

To study the adverse effects reported by the sample who underwent repeated chemical hair relaxing.

SETTINGS AND DESIGN

Cross-sectional questionnaire based study done on a sample taken from a medical college and hospital campus in Mangalore.

MATERIALS AND METHODS

The sample was restricted to females and to those who underwent it more than once. A questionnaire was given to a sample of 90, which matched our criteria.

STATISTICAL ANALYSIS

SPSS software 17.

RESULTS

Adverse effects reported by the sample after undergoing the procedure were found to be a high 95.56%, out of which the following are the common adverse effects reported; frizzy hair in 67%, dandruff in 61%, hair loss in 47%, thinning and weakening of hair in 40%, greying of hair 22%, and split ends in only 17%.

CONCLUSIONS

Very few studies have been conducted on the adverse effects of hair straightening products in India. From our study, it can be stated that most of the samples had adverse effects, which was as high as 95.56%. Hence from the details elicited from this study, we can conclude that, usage of chemical hair relaxers does cause adverse effects and is "not a myth." Thus, it is necessary to make available a less harmful chemical hair relaxer to the society.

摘要

背景

头发在塑造个人形象和建立自信方面起着重要作用。如今,化学直发剂在社会中被广泛使用。我们记录了使用过任何一种专业化学直发剂的样本所报告的不良反应。

目的

研究接受反复化学直发的样本所报告的不良反应。

设置与设计

基于横断面问卷调查的研究,样本取自芒格洛尔的一所医学院和医院校园。

材料与方法

样本仅限于女性且是接受过不止一次化学直发的人群。向90名符合我们标准的样本发放了问卷。

统计分析

使用SPSS软件17。

结果

样本在接受化学直发后报告的不良反应高达95.56%,其中常见的不良反应如下:67%出现毛糙头发,61%有头皮屑,47%有脱发,40%头发变细变软,22%头发变白,仅有17%有发梢分叉。

结论

在印度,针对直发产品不良反应的研究很少。从我们的研究可以看出,大多数样本都有不良反应,高达95.56%。因此,从本研究得出的细节可以推断,使用化学直发剂确实会产生不良反应,并非“无稽之谈”。所以,有必要向社会提供危害较小的化学直发剂。
