I thought that at first as well but none of them are gray. I've let some of them stay for 6 months and they just keep staying that color. I've pulled out so many of them to see if they grow out grey but they continue growing out that color. Tbh it's terrifying. My father has had these genes from when he was little that changed his hair color all the time. He also had this thing we're his eye color would change from blue, green and gray. Not just little but his entire eye would change color. The eyes are still like that. He always talked about how terrifying that was. I might think that there might be something like that because my father used/has that. It's super weird
