Lunar Tides. Dark and luscious, the deep colors feature velvet tones that are highly pigmented to last long and create richer tones. Cerulean Sea is a one-of-a-kind highly pigmented dark teal dye. The dyes are non-damaging and do not require developer. All the dyes are vegan & cruelty-free! All colored hair dyes require light blonde or platinum hair prior to application. Our shades appear different in the bottle than they do on the hair. Please do a strand test before doing an all-over application.
