§ Mrs. Joyce Butlerasked the Secretary of State for Prices and Consumer Protection if she will introduce regulations to ensure that all permanent and semi-permanent hair dyes containing aromatic amines are so labelled, in view of the possible cancer hazard from their use.
Mr. Alan WilliamsStudies being carried out in the USA and the United Kingdom have shown mutagenic effects in some hair dyes. But long-term American tests on animals for cancer have so far produced no evidence that the dyes which have been subjected to mutagenicity testing produce cancer. Further studies are being carried out. I am considering, with the help of the Government's medical advisers, whether any action is necessary in the meantime.
