Henna comes from a plant of the privet family, and has been known for centuries for its superb hair conditioning and coloring properties. No other substance, whether natural or synthetic, will strengthen the hair and give it shine as effectively as HENNA. Henna contains "lawsonia", this substance provides the well known conditioning and coloring properties associated with our Henna Powders. Henna Powder colors the hair in two ways, by penetration and by staining. Henna molecules have a chemical affinity with keratin (hair) molecules, and thus the pigment can pass freely into the hair. The penetration of lawsonia imparts both color and condition into the hair and it closes and strengthens the outer cuticle of the hair, thus giving the superb shine and conditioning effect, which is the unique feature of Henna.
