Shea butter is a solid fatty oil that is derived from the nuts of the Karite trees (also known as Mangifolia), predominantly found in Africa (grows wild in the equatorial belt of central Africa between Gambia and Sudan where oil palms do not grow because of insufficient precipitation). The Karite tree bears the fruits and the nuts inside the fruits contain shea butter. The nuts are then crushed, boiled, and manipulated in order to extract a light-colored fat, which is commonly referred to as shea butter.
Pure shea butter resembles lumps of hard caramel ice cream. Being edible, shea butter is often used in food preparations. It has gained huge popularity in the western world due to its widespread use in several beauty products such as lotions, cosmetics, shampoos, conditioners and many more.
What Is Shea Butter?
The main components of shea butter include oleic acid, stearic acid, linoleic acid, etc. It gets absorbed quickly into the skin as it melts at body temperature. Shea butter may be refined or unrefined. Raw or unrefined shea butter is the purest form of shea butter, which is the most natural and the least processed. Since it is extracted manually, it is able to retain its vitamins, minerals and other natural properties. Refined shea butter, on the other hand, is the processed form of butter.
Health Benefits Of Shea Butter
Shea butter exhibits several health benefits, particularly for the skin and the hair. It is used in a variety of cosmetics and medicinal formulas in combination with other botanical ingredients. Some of the health benefits of shea butter are given below.
1. Healing Qualities:
Shea butter is known for its healing properties that can be attributed to the presence of several fatty acids and plant sterols such as oleic, palmitic, stearic and linolenic acids. These oil-soluble components do not undergo saponification or convert into soap on coming in contact with alkali. Shea butter is more non-saponifiable than other nut oils and fats, thus imparting it a great healing potential for the skin. Raw, unrefined shea butter is effective in curing skin rashes, skin peeling after tanning, scars, stretch marks, frost bites, burns, athletes foot, insect bites and stings, arthritis, and muscle fatigue.
2. Antioxidant Qualities:
Shea butter contains plant antioxidants, such as vitamins A and E, as well as catechins. The vitamins A and E protect the cells from free radicals and environmental damage. The cinnamic acid esters in the shea fat help in preventing skin damage from ultraviolet radiation.

12. Hair Protection:
Shea butter provides protection to the hair against the harmful free radicals in the air and water and harsh weather conditions. Moreover, shea butter has a low amount of SPF that is sufficient to protect the hair from sun damage caused due to the exposure to ultraviolet radiation and repairs the damage that has already been caused by the harsh weather and the sun. This is largely due to the fact that once absorbed, shea butter coats the hair shaft so that it is protected from a heat tool or any other damaging material being passed along the hair. This is particularly beneficial for processed or colored hair. It also protects the hair against salt and chlorine when applied before swimming.
13. Hair Softener:
Shea butter is great for softening and revitalizing damaged and brittle hair. Due to its non-greasy nature, it helps to control and spread the excess oil in the scalp.

Shea butter should be applied twice a week for hair growth, improving the hair texture and moisturizing the hair.

- Fatty Acids: Shea butter, basically, is comprised of five principal fatty acids namely palmitic, stearic, oleic, linoleic and arachidic acids, with a higher proportion of stearic and oleic acids, that together accounts for 85-90% of fatty acids. Stearic acid provides a solid consistency, whereas oleic acid influences the hardness or softness of the shea butter.
- Phenolics: Phenolic compounds are known for their antioxidant properties. Shea butter contains 10 phenolic compounds, eight of which are catechins. Traditionally extracted shea butter has higher phenolic levels than that extracted with hexane. In fact, the catechin content of shea butter is higher than the total phenolic content of ripe olives. The overall concentration and relative percentage of the shea kernels varies from region to region, depending upon the level of environmental stress endured by the trees.
