Persians have used Saffron, Pistachio and Rose in beauty rituals for centuries. Saffron, a spice worth more than its weight in gold, is used to strengthen hair. Pistachio nourishes and moisturizes for bouncy and smooth hair. Adored in Persian poetry and art, Rose has long been used to make hair smooth and shiny. Using modern chemistry, these ingredients now combined give a potent boost to hair longevity.
