Shampoos, conditioners and styling products can all leave residue behind, even after repeated cleansing. This build up prevents natural oils and nutrients from reaching the hair shaft, resulting in itchy scalps and limp locks. The TRESemmé Purify and Replenish system resets the balance by gently clarifying and lightly hydrating, leaving healthy-looking hair that feels nourished from root to tip. For the full refresh start by clarifying with TRESemmé Purify and Replenish Deep Cleanse Shampoo, gentle enough for daily use, to remove product build up and dirt. Follow with TRESemmé Purify and Replenish Conditioner to moisturize without leaving locks heavy, revealing residue-free, nourished hair. On-the-go? TRESemmé Cleanse and Replenish 2-in-1 Shampoo + Conditioner provides purification and optimal moisture in just one step, perfect for travelling or the gym.
