I have a group of friends who hang out together a lot, men and women all in their mid to late 30's, some of whom are thinning and most of whom are greying. I have never told them I wear, and I don't think they suspect me of wearing (but you never know for sure). Every few months while sitting around the table eating a meal, one of them will bring up the subject of greying. Then they take turns showing their gray hairs. I always start to get anxious when this happens. At age 39, I am wearing a full cap and haven't had gray hair put in yet. So I am the only one in the group without any gray hair. I will usually say I have a little gray but I use Just for Men. Sometimes someone will say that I'm lucky I still have all my hair. I say I know I am. But inside I feel nervous, because I don't know if they suspect me to be wearing. Is it okay on my part to handle it the way I do? Or do I owe some level of truth?
