The professional quality formula contains a heat activated complex to help protect your hair during heat styling, whilst smoothing frizz and sealing in shine. Spray liberally onto your hair before blow-drying or heat styling to keep it shiny and soft. The moisture-locking vitamin complex helps to prevent hair from becoming brittle and dull. Brand: Tresemme.
