A: It's so rare that I hear from someone who doesn't want to color or use any styling products! I can only guess at your motivation (you're a purist?), but I admire your resolve to keep it simple. What you need most of all is the right cut, says hairstylist Mario Russo of the Mario Russo Salons in Boston. Go for a shoulder-length bob with layers, which should give you a little lift and fullness. Use a shampoo made specifically for fine hair (try Biolage Volumatherapie Bodifying Shampoo, $14), and a light detangler (like Ojon Revitalizing Mist, $26)—a heavy conditioner will weigh your hair down. When your hair is almost dry, style it with a round brush and a blow-dryer on a low setting.
Bottom line: Start with a great cut; fine hair requires more maintenance than thick hair, so see your stylist regularly (every six weeks or so) for trims.
