A permanent hair dyeing composition, comprising:
- an oxidation dye precursor:
- a coupler;
- 0.01 to 10 wt. % of an oxyalkylenized xanthane gum;
- and
- 0.1 to 20 wt. % of a salt of an inorganic acid or an organic acid.
A permanent hair dye composition comprising 0.1 to 20 wt. % of an oxidation dye precursor, a coupler, 0.1 to 5 wt. % of an oxyalkylenized xanthan gum, and 0.1 to 20 wt. % of a salt of an inorganic acid or an organic acid, wherein the composition has a pH of from 6 to 9.5.
A permanent hair dyeing process, which comprises applying to hair a composition comprising 0.1 to 20 wt. % of an oxidation dye precursor, a coupler, 0.1 to 20 wt. % of a salt of an inorganic acid or an organic acid, and 0.1 to 5 wt. % of an oxyalkylenized xanthane gum, wherein the composition has a pH from 6 to 9.5.
