‘Truth about Hair Colours?’
Hair Colours that claim to be Ammonia-free contain Ethanolamine and Resorcinol. These do the same work that Ammonia does, though there are no burning fumes or smell as in Ammonia. So people get easily misled into believing that they are using something milder or safer!
BEWARE OF HENNA COLOURS!! Manufacturers mix henna with other chemical dyes such as PPD without mentioning these additives on the label of Henna packages and these may show similar toxic side effects. PPD is mixed with natural henna to give it an ebony colour (black henna) instead of the orange/reddish colour given by natural henna.
