Third-ranked home shopping network ShopNBC has been struggling, and its strategy now is to diversify and not depend so much on jewelry sales. As a result, it is becoming more and more like QVC and HSN every day. It’s no big surprise, since ShopNBC is now run by former QVC executives.

Tuesday’s ShopNBC Top Value of the Day are clip-in hair extensions from hair stylist Ted Gibson, at $100 a pop.

Does any of that sound familiar? Well, QVC just rolled out a line of hair extensions, Hairdo by Jessica Simpson & Ken Paves, from the blonde singer’s hair stylist Paves.

That Paves/Simpson line used to be on HSN, but switched over to QVC. We could swear that TV chef Rachael Ray was wearing hair extensions of some sort — maybe from Paves — when she appeared on QVC last week, despite her claim she was growing out her hair. Last time we saw her, her hair was chin-length, and it was down her shoulders when she appeared on QVC.

Despite the exit of Paves and Simpson. HSN still sells hair extensions from Toni Bratton.

The Gibson hair extensions are all part of ShopNBC’s first beauty and style week.
