Steve Martin appears to have gone gray prematurely, with reports placing the change in his late 20s and saying he was fully silver by about age 32. One source specifically notes he was already gray by 32, based on a 1977 Rolling Stone profile.

Quick scoop

  • Early signs: late 20s.
  • Mostly/fully gray: by his early 30s, around 32.
  • Why the confusion: older photos from the late 1960s and early 1970s show darker hair, so the shift happened gradually rather than all at once.

In plain terms

If you’re asking when he first started going gray , the best-supported answer is in his late 20s. If you mean when his gray hair became part of his signature look, that was by the early 1970s to early 1980s , and definitely by his early 30s.

TL;DR: Steve Martin went gray very young — late 20s, fully by about 32.
