“…In the present study, a significant increase in the frequency of individuals with gray hair was observed in three groups (group I, II, III) when compared with the control (group IV) ( P < 0.05). This was in accordance with the findings of Jo et al .,[3] who concluded that the risk of hair graying increased by 14.9% each year ( P < 0.001) and the risk in smokers was 1.99 times higher than that in non-smokers ( P = 0.008).…”

“…The aging phenotype of hair manifests as a decrease of melanocyte function or graying, and decrease in hair production or alopecia. [2] This was in accordance with the findings of Jo et al .,[3] who concluded that age was significantly correlated with hair graying, and the prevalence of gray hair by age was 51.5% in their thirties, 81.1% in their forties, and 95.3% in their fifties.…”

Aims and Objectives:To determine the association between smoking, chewing tobacco (gutka), and age of individual on graying of hair.Materials and Methods:The present study was conducted on 120 patients attending the Outpatient Department of the DJ College of Dental Sciences and Research, Modinagar, UP. The individuals were classified into four groups (group I, II, III, IV) on the basis of the form of tobacco use (smoking or chewing). The Pearson correlation coefficient was utilized to find the correlation between the mean percentage of individuals with gray hair, risk multiplication factor (RMF), and age of the individual.Results:Mean percentage of individual with gray hair and RMF (r = 0.6487) are found to be positively associated. A significant and positive correlation was observed between the age of the individual and the frequency of individuals with gray hair.Conclusion:This study suggests that there is a significant association between tobacco use and aging on graying of hair.

“…In addition, we have found that the prevalence of hair dyeing is not dependent on hair loss, which indicates that hair dyeing behavior is not affected by existing hair loss. In fact, hair loss was reported not to be significantly correlated with graying11.…”

“…We believe this is also reflects different levels of concern regarding hair graying among different age groups. In Korea, the onset of graying normally occurs in the third or fourth decade of life11. A previous report published in Korea did reveal that 62.7% of 1,499 university freshmen had their hair dyed at least once in their life12, but this prevalence figure was determined without the purpose of hair dyeing in study design, whereas the current study was limited to hair dyeing specifically for masking of gray hair, which would explain why our results indicate a much lower hair-dyeing prevalence among the younger population.…”

BackgroundHair graying is considered as a part of normal ageing process. Nonetheless, this process raises a significant cosmetic concern, especially among ethnic Korean elderly whose baseline hair color is black. For this reason, Korean elderly dye their hair with frequency despite the risk of dermatologic problems such as allergic contact dermatitis.ObjectiveIn this study, the authors investigate the prevalence and pattern of hair dyeing and its relation with scalp diseases in Korea.MethodsSix hundred twenty subjects (330 men and 290 women) with graying hair were given a questionnaire survery and underwent a physical examination.ResultsOf the 620 total, 272 subjects (43.9%) dyed their hair. Hair dyeing was significantly more frequent among women than among men (p<0.001). Subjects from 50 to 69 years of age showed higher prevalence of hair dyeing when compared to either younger or older groups. Subjective self-assessment of the extent of hair graying was associated with increased prevalence of hair dyeing, that is, individuals who feel graying has advanced by more than 20% of the overall hair were much more likely to dye their hair (p<0.001). Hair dyeing did not correlate with either alopecia or scalp disease.ConclusionOur survey has found that the prevalence of hair dyeing is higher among Korean women than men. People in their fifties and sixties and people with more than 20% extent of grayness were more likely to dye their hair than otherwise. Hair dyeing was not associated with any increase in the prevalence of scalp diseases.
