If your maternal grandfather had one, you could conceivably have inherited it, but hair genetics are very dicey, and extremely hard to predict, so unfortunately I can’t give you a definitive yes or no answer. Your maternal grandfather is definitely a factor, but so is every other one of your male family members. People who you directly descend from are your best bets (father, grandfathers), then people who your parents are directly related to (uncles), then people more tangentially related to you (male cousins).
