Or not.

Rihanna spends way more than Kate Middleton on her constantly changing locks — an estimated $22,000 a week, per the Daily Mail — but the Duchess of Cambridge doesn’t skimp on her flowing tresses.

According to Us Weekly, Kate hits up her longtime salon in London’s Chelsea neighborhood, Richard Ward Hair and Metrospa, three times a week for blowouts that set her back at least $75.

If you extrapolate that out to a year, the Duchess would shell out as much as $11,700 for blowouts alone.

We’re blown away.
