Product description Bio Henna contains no chemicals. After dyeing your hair with Natural Bio Henna Dark Chocolate, youll achieve a cool-toned, dark brown color. Bio Henna conditions your hair, deeply nourishing it, improving its volume, and smoothing its structure. With subsequent applications of Bio Henna, your hair color will deepen, become more vibrant, and saturated. The condition of your hair will also improve significantly, becoming visibly thicker, new baby hairs will grow, and your scalp will regain its balance—no flaking or excessive oiliness. Consistency: Finely ground powder. After mixing, it should have the consistency of a thick paste so that it doesnt run when applied. Fragrance: Intense herbal. Suitable for: Everyone, but for completely gray, blonde, or chemically bleached hair, test a strand first to see if the resulting color suits you!
