"For short haircuts, you want to keep tapering the back and sides and let the top grow out over the layers, and then as it grows it will keep going over into a bob," Stephen explains. "But the number one tip is patience." You can expect to see many more one-sided looks as Rosario's hair grows out in the coming months. But what if you went for the double-sided mohawk look à la Rihanna?"If you shaved both sides off, I think it's always good to let one side grow back fully," Stephen says. "When I did Ri, we shaved both sides. When we decided to let it grow back, we kept cutting one side and let the other wolf out, and then we'll switch it over. Your other option is to add extensions in."
