Meet Martha Truslow Smith, a graphic designer from North Carolina who got her first gray hair at the age of 14, as she wrote once on social media. Smith started coloring her hair to hide what was happening, but instead of gaining assurance, she felt anxious and misrepresented. Yes, Smith decided to stop fighting nature: by embracing the gray, and letting it grow out, regardless of her age. She started an Instagram account to document her journey -- you can find Smith @grombre -- and, get ready for this, at last check, the page had about 193,000 followers. Going “grombre,” by the way, isn’t so much a trend as much as it is a movement.
