Slip: The Duchess' chic up-do inadvertently showed off a glimpse of grey on either side of her ponytail
Not long to go: Although the NHS says hair dye is OK during pregnancy, Kate has chosen not to risk it
She's famous for her glossy chestnut locks but it seems that pregnancy has been taking its toll on the Duchess of Cambridge's beauty regime.
Touring the West Midlands with her hair in an elegant half-up hairstyle, a glimpse of grey could be seen peeping from beneath the knot holding it in place.
Of course, this is not the first time the 33-year-old royal has been snapped showing off a silver streak, with the most recent sighting coming early in January during a shopping trip.
Part of the reason for the spate of recent silver sightings is her second pregnancy: the Duchess has reportedly given up many of her beauty treats in a bid to avoid harming her baby.
Hair dye is one such beauty essential often given a wide berth by mothers-to-be, although celebrity hairstylist Jo Hansford says going without isn't always required.
