Dyeing hair = Cancer???

The news yesterday reported that a woman in China got cancer due to constant dyeing of her hair for 15 years.......

so my mum after seeing the news.....started chiding for always dyeing my hair......n said I don't believe her when she told me dyeing hair can cause cancer.......so anyway she keeps nagging away.....n I could only keep quiet......

Though there are reports from US that people may get cancer from excessive dyeing.......it's not really proven yet.....n so far those who get cancer from dyeing hair......it's juz a few cases.......Besides I only dye my hair once a year.......so I don't know why my mum muz keep nagging me......I know she has my interests at heart.......but.......she need not nag for so long right???

Anyway......I better keep off from dyeing my hair for the time being......or else....my mum will start her 'lecture' again.......
