Saryna Key Professional has harnessed the power of the Shea nut and made it the signature ingredient in its four new series of Shea butter lines individually formulated to nourish damaged, curly, color treated and fine hair. Cracked open, the Shea nut reveals butter rich in vitamins A, E and F, essential fatty acids, proteins and cinnamic acid. These natural properties provide intense moisture, promote cell renewal, increase scalp circulation, and protect against harmful UV rays and free radical damage. Formulations also include natural additives such as wheat protein, apple, cotton and silk proteins and amino acids.
