Billed as --a pampering retreat for girls,-- Spa Ladi-da! is a spa designed for girls ages 7 to 14, so naturally hot pink, lime green and other bright colors adorn the walls of this tween-focused store. Young clients can be found dancing to hip-hop, top 40, inspirational and other age-appropriate music videos that play nonstop. After getting their makeovers or manicures, the girls can relax on oversized beanbags, sip tasty drinks and munch on healthy foods. Spa Ladi-da! is the brainchild of Detra Jones, a Charlotte, NC-area mother of two girls, who came up with the idea more than a year before the store s grand opening last October. --My daughters were 10 and 12 at the time,-- she says. --When I went to get my nails done, sometimes they came with me. But I realized there wasn t a place designed for them.-- She thought that there ought to be such a place. Jones shared her idea with her husband, Victor, who immediately knew his wife had hit on something. --For me, it was a no-brainer,-- says Victor. --I knew it was something that my girls would love,-- he says.
