It is always desirable to use unflavored and unscented shea butter where possible. It is important that you understand that scent and fragrance are often added to shea butter to mask the unpleasant smell of rancid shea butter. Rancid shea butter is so wide spread in the USA market that some people think the horrible smell of rancid shea butter is actually what shea butter should smell like.
Fresh shea butter needs no added scent or fragrance. Unfortunately, beauty stores are not a place to find high quality shea butter. Once the fragrance is added it is difficult to differentiate rancid butter from higher grades. The most reliable source for high quality shea butter is found with those displaying the Seal of the American Shea Butter Institute.
