Abstract
Abstract Oxidative hair dyeing preparation having a content of a 1-hydroxyalkyl-2,5-diaminobenzene having the formula ##STR1## as developing substance, wherein R denotes hydroxyalkyl having 1 to 4 carbon atoms, or their salts with inorganic or organic acids. Preferably, these hair dyeing preparations will contain 1-hydroxymethyl-2,5-diaminobenzene in a concentration of approximately 0.1 to 3.0 percent by weight, this either alone as a developing substance, or in combination with the conventional coupling substances.

Dependent Claim
101 words
A process for the oxidative dyeing of human hair which comprises, shortly before use admixing about 10 g of a composition according to claim 1 with about 10 ml of a 6% solution of hydrogen peroxide or an addition compound thereof with one of urea, melamine or sodium borate, applying an effective amount of the resultant mixture for coloring the hair onto the hair, allowing it to remain on and in contact with the hair for from 10 to 45 minutes at a temperature of from 15° to 50° C., rinsing the hair with water and allowing the hair to dry.
