We all know what happens to fine hair, specially in the autumn and winter months, it can lie flat and lifeless on your scalp or become flyaway and prone to static.
Davines vegan hair care range has a product range for precisely this type, it is the Volu shampoo & Volu hair mist. The latter is my favourite. You leave it on to give volume to the hair from the root. It does not weigh the hair down and leaves it soft and shiny.
