Shea butter is a creamy, solid oil with many benefits for skin and hair. Shea is extracted from the seeds in the fruits of the Shea or Karite tree grown in West and Central sub-Saharan Africa. The word “Shea” derives from the word s’í, which is the tree’s name in the West African language of Bamana.
Authentic shea butter should have a slightly yellow or beige color to it. Variation in color depends on the quality and type of the shea nuts, and the processing method used to produce the shea butter.

Shea butter is extracted from a fat that contains several acids including: oleic, stearic, linoleic, palmitic, and arachidonic acids. Shea butter is popular as it absorbs quickly into the skin without leaving a greasy feeling as it melts at body temperature. Its uniqueness is due to its high content of unsaponifiables and cinnamic esters, which have antimicrobial and moisturizing properties and provide protection from ultraviolet sunrays. The unsaponifiable fraction (anywhere from 5-17%) in shea butter consists of a large group of plant compounds that contributes to the regeneration process that heals dry skin. Shea butter also contains natural levels of Vitamins A, E, and F, which contribute to healthy skin. Vitamins A and E help keep the skin healthy by preventing wrinkles and hydrating the skin. Vitamin F acts as a skin rejuvenator and protector. Shea butter also inhibits elastase, an enzyme that breaks elastin and other proteins, which helps skin maintain elasticity.
