Swooping in like a black knight in shining armor,  Richelieu Dennis, who not too long ago, was demonized by black women for marketing a product to "women not of color", has purchased Essence Communications from Time Inc.   BRAVO Mr. Dennis!  And thank you!  We needed that, more than shampoo and moisturizer, frankly.   Dennis, the founder of Shea Moisture hair and skin care brands, just recently sold the portfolio to Unilever, parent company of Dove.   I had the opportunity to meet Mr. Dennis very briefly last spring when he made an appearance at the Odyssey Media Business Retreat.  He came for the sole purpose of explaining the marketing faux pas that sent black women into a lather, literally and to apologize for it.   “Our focus here will be on ensuring that Essence reaches its full potential via heightened capabilities, technology, products and touch points that super-serve the interests of black women locally and globally.” Dennis is quoted as saying.
