Horst Rechelbacher's much-talked about Intelligent Nutrients line of edible, organic hair and body products will finally be released in full this May. He partnered with Regis Corp., which seems to have provided just the kick in the pants the creative genius needed. Gordon Nelson, executive vp of Regis told me yesterday that the full collection of products will be introduced in May at a New York event. New York? But Horst is here, as is his cool IN store and cafe, and Regis is based in Minneapolis as well. "We'll have a party in Minneapolis, too," Nelson assured me, "but we're launching in New York." I did at least get a whiff of the shampoo - right off of Nelson's head. Smelled divine - good enough to drink.
