Hi there!
If you wish to cover your greys then I would suggest tinting the roots and then going for natural ends using the Davines Flamboyage colouring technique. This will keep your hair looking natural and is easy to maintain.
For dry hair: try an in-salon Davines Naturaltech nourishing treatment to moisturise and restructure the hair. The homecare range is also avaliable to keep the hair nice and moisturised.
