Henna-Persian Sherry gently coats the hair shaft with 100% organic color while it conditions, covers gray, and enhances shine, body, and texture. Rainbow Henna is the dried, powdered leaves of small shrubs native to Iran, West Asia and North Africa, called Lawsonia. The leaves are picked, dried and pulverized to a fine powder. The type of climate and richness of the soil where the shrubs are grown, greatly affect the quality of the henna. The finest grade Henna powder comes from Persia. Because Henna is a vegatable product, it is a natural base for hair coloring and cosmetic use. It is an alternative to the chemical tints which are controversial to health considerations.
