The Bumble & bumble Thickening Volume Shampoo is an amplifying formula for larger than life locks. Created for those with fine, limp or thinning hair, the wonder wash will make it feel thicker, fuller & well nourished. It moisturises without weighing hair down & helps to smooth split ends & fly-aways. The colour compatible Thickening Volume Shampoo is the first step in your journey to full & glamorous hair. Simply wet the hair, lather the shampoo in your palms, massage through & rinse away thoroughly. Follow with the Bumble & bumble Thickening Conditioner.
