Want to add volume to your hair, while still keeping it feeling light and vibrant? TRESemmé 24H Volume is specially formulated to help fine and flat hair look and feel thicker and healthier. The combination of collagen and silk proteins gives your hair fullness and volume for 24 hours, without weighing it down. The result: Thicker, shinier hair with natural and amazing movement. How to use 24H Volume: Squeeze a generous amount of shampoo into your palm and massage it into wet hair. Gently massage the scalp and roots, and work into a lather. Then gently press the shampoo into the hair, from the roots to the ends. Rinse thoroughly. For extra volume, we recommend continuing the treatment with TRESemmé 24H Volume conditioner.
