<p>The present invention provides a solid wash resistant hair colourant stick composition comprising an intimate admixture of a wash resistant hair dye with a physiologically acceptable compatible solid base, and preferably an effective amount of a lathering component. The base has a hardness which is sufficiently high to provide substantial dimensional stability under light to moderate manual pressure under ambient temperatures. The composition also has a combination of hardness, texture and water solubility characteristics for allowing easy gliding of the stick over a mass of damp hair and transfer of stick material thereto under light to moderate manual pressure in a generally smooth and controlled manner substantially without fracture of the stick or substantially discontinuous deposition of material.</p> |
