More than half of us will suffer from thinning hair at some point in our lives. While root causes vary, these products should help plump up most scraggy strands:
> Rene Furterer Forticea Stimulating Shampoo ($23; sephora.com) This invigorating formula revs up scalp circulation, helping promote more vigorous hair growth.
> Living Proof Full Shampoo and Conditioner ($24 each; sephora.com) A sulfate- free duo, this set thoroughly cleans hair (buildup weighs down thin hair, exaggerating its limpness) without drying it out or stripping color.
> Oscar Blandi Hair Lift ($35; oscarblandi.com) A combo of rice-starch powder and sodium hyaluronate (said to plump hair with moisture), this styler claims to make hair look 47 percent thicker.
