Cantu Leave-In Conditioner deeply moisturises hair, leaving it with natural, long-lasting hydration. Its formula is designed to strengthen the hair fibre, providing spectacular shine and a healthier look. It also helps to reduce drying time, making hair easier to comb and manage. How to use. Apply a generous amount to damp hair, starting at the ends and working towards the roots. Comb through to distribute the product evenly. Do not rinse. Style as usual for moisturised, strong and shiny hair.
