The Daily Mail is reporting more than $10,000!
That's what it cost to have her hair dresser travel with her on the royal couple's recent trip to Australia. That is not including the costs of travel.
The Daily Mail says the hair stylist Amanda Cook Tucker charges around $250 for a cut and blow dry, but charged Kate twice that since it was an overseas trip.
Kate's clothing budget for the trip reportedly totaled over $100,000, but reports suggest that she saved money by doing her own makeup.
