Egyptian black seed oil and henna have both been used by ancient Egyptians to strengthen their hair and to promote hair growth. Black seed oil helps feed hair vital nutrients often washed out or repleted with modern hair formulas. Our Nile grown henna is rich in a multitude of nutrients and the Nile silt intensifies the mineral content of the henna in comparison to henna grown in other parts of the world. We use a generous amount of henna in our natural shampoo, not just a few drops of an extract. When mixed with water henna makes the hair colored, however, when we cook the henna into our shampoo it no longer colors the hair. Neutral henna used in many products, is actually not henna at all. It is a completely different plant and does not have the same strengthening properties of real henna.
