The TRESemmé Beauty Full Volume Regim Kit includes Pre Wash Conditioner (16.5 oz), Shampoo (25 oz), and Hair Maximizer (2.3 oz). Using conditioner after you shampoo can weigh hair down and leave it flat. TRESemmé Beauty-Full Volume Reverse System is a game-changing regimen that gives your hair amazing body and bounce. TRESemmé Beauty-Full Volume Pre-Wash Conditioner is designed to be used before the TRESemmé Beauty-Full Volume Shampoo, to leave hair smooth and polished but still full of bounce. TRESemmé Beauty-Full Volume Hair Maximizer lets you have it all - hair that's got bounce and body, but still feels soft.
