My hair, which used to be limp and lacking volume, has become soft since I started using Elastine Biotin & Marine Collagen. My hair has thinned out and tends to droop easily, and while I can feel the strength at the roots gradually decreasing as I age, the softness is exceptional—perhaps because it is Elastine. My scalp usually gets irritated and breaks out if I use the wrong shampoo, but I haven't experienced that even once since using this, so I am very satisfied with the product. It has a subtle, refreshing scent, and people passing by often comment on how nice it smells. If you feel you really need "bouncy volume," I highly recommend giving this a try.
