My mom always told me that dying my hair would do me more bad than good ... I didn't get it at first ... But I did notice that many women who dyed their hair, either ended up getting some sort of skin allergy or getting thin hair!
Mom always said that those chemicals in the hair dye products were bad ... Turns out she was right!
A new research conducted by the scientists advising the European Commission found that most hair dyes contain skin sensitisers, chemicals that trigger allergies.

They found ten to be "extreme" sensitisers, thirteen were "strong" & four "moderate".
A few years back, another research by the same scientists, found that there is a link between long-term use of permanent hair dyes & the development of bladder cancer!
This tells you to 'Stay away from hair dyes & be happy with your natural hair color!'
