Celebrity manicurist Lisa Logan, who works on stars like Mary J. Blige and Beyonce, shares nail favorites and tips in the February issue of Essence. She says Mary J. Blige likes conservative nails, and Beyonce wore a purple version of the new Minx Teaser line in her "Video Phone" clip. Slightly pointed nails elongate, purple compliments many complexions, sprakle is still in, and lace overlay means texture is important.
