I like to think that Sherlock ‘you’re so vain’ Holmes would go into a tizzy the moment he finds a gray hair amongst his curls. He would go into a strop, researching dye options and detractors, obsessing to the point of madness. That is, until he discovers that the gray at his temples lends him a distinguished air… one that Molly finds more than a little attractive. Suddenly, the gray hairs don’t seem so bad and he uses this new aura to full effect. On her.
