Sahara Herbal Hair Color coats each hair strand with a coloring and strengthening layer that actually adds volume and shine. Only henna and other natural plant colorants, such as walnut shells and beet root, provide the color. Plant-derived conditioners make application and comb-out easier, and improve your overall hair structure for a softer, healthier texture. Sahara will produce a reddish golden tone on light blonde to medium blonde hair. Depending on your beginning hair color, your color result should lie within the shown range.
