I leave the conditioner in for at least five minutes in the shower to take care of my ends and get the texture back. It’s important for me to have healthy hair. It’s a big thing for me.” As for skincare and makeup, “I hydrate, hydrate, hydrate,” the Duchess told us. She uses eye cream and mineral makeup, and washes her face very night.
