Get the look: zosia mamet goes silver

Zosia Mamet made a style statement this week, stepping out on the red carpet with a festive silver 'do. The GIRLS actress has been on her A-game all year with her hair - first switching her long, luxe waves for an on-trend chin-length bob, then going bleach blonde in September. Grey might not be the easiest colour to pull off, but it's definitely a popular choice - here, Schwarzkopf Professional British Colour Technician of the Year Clayde Baumann tells us how to get the look.

We love this palette at D&J and its a very current tone in our 2015 Collection, Urban Camouflage. The key with this tone is to ensure that your underlying pigment is nothing stronger than a pale yellow. If using brands with a similiar numbering system to Wella, I'd incorporate 1-2g of a strong blue pigment (I.e. 2/8 Colour Touch) into a very diluted ash toners (I.e. 10/6 + 8/81). I'd either apply this to wet hair or add an entire extra part of 1.9% developer to ensure a slow and controlled tone, so a total of a (1:3 ratio). Alter your application method to suit varied porosity levels for an even graphite-slate finish or to create pocketed variants of tone. Development time will vary according to the hair condition.
