Forget hair dyes, try natural colours to cover grey strands (Gallery)

Greying of hair is a condition that cannot be reversed, but can be effectively concealed by the use of hair colours. However, before you reach out for that synthetic hair dye, pay attention to what medical researchers have to say about its safety. Hair dyes may contain certain chemicals that go by the name of secondary amines and these can react with exhaust from vehicles as well as tobacco smoke, to form other compounds called N-nitrosamines that have been implicated in cancer. Given the high levels of pollution, and our exposure to people who smoke, this is indeed a cause of concern. Giving up the use of hair dyes means compromising on appearance and not many of us find that acceptable. What can be done? The answer – go natural. Here are a few hair colouring ideas to try at home.
