Gwyn has been part of Ancient Sunrise since her mother, Catherine Cartwright-Jones started the business. Her main job is seeing to it that we have on hand the henna, indigo and cassia that are the main ingredients of our hair color products. Because all of those ingredients have to be shipped from South Asia, it can be challenging work.

Lawsone in the henna will bind permanently to keratin without boiling1 or mordants2 if mixed with a mildly acidic liquid.3 The acid penetrates the cellulostic material in the powdered leaves, and makes the lawsone available for binding. As long as the mix is hydrogen-rich and mildly acidic4 the hydrogens on the corners of the lawsone molecule will be preserved, so the dye will bind to the keratin of hair in a Michael reaction. Lawsone binds so strongly to keratin that even repeated bleaching will not completely remove the color.
