    Fabulous for volume

    [This review was collected as part of a promotion.] I use this regularly and it’s making such a difference to the thickness of my hair already. New bits are growing especially around the sides and front. Still a way to go yet as this is my first bottle but I’m very pleased with the results so far and would highly recommend this one for anyone wanting thicker hair.
