Washington n (CNN) Rep. Tulsi Gabbard, an Iraq War veteran who is running for the Democratic nomination for president, recently revealed that she doesn't dye a gray streak in her hair because she wants it to serve as a "remembrance" of US service members killed in the Iraq War.

"No, I'm not going to fix that gray strand. I don't know what you mean by 'fix.' If you mean dye, no, I'm not going to dye it. I actually started going gray in that one spot during and after my first deployment to Iraq. And so I keep it as just a remembrance of those who we lost there and the cost of war and why we fight so hard for peace," the Hawaii Democrat said in an Instagram Live video posted over the weekend, apparently in response to a user who commented on the gray streak.

The touch of gray is noticeable in the dark hair of the congresswoman, who was deployed to Iraq in 2004 as a member of the Hawaii Army National Guard.

Gabbard's military experience has been prominently featured in her campaign. During the second night of July's debates, she wielded her credentials as an Iraq War veteran to speak about foreign policy decisions with a personal tone.
