I started Propecia/Minoxidil at age 41. The hair on the lower sides + nape of my neck started turning all white and getting VERY thin. Both thin in density & thin hairs. That began before Propecia/Minoxidil, but progressed rapidly since. I started dying my hair on sides/back around age 30. Could dying that hair have causing damage and caused the hair to stop growing? I kept that hair VERY short, so the dye was in direct contact with my skin. Retrograde Alopecia? Or Damage From Hair Dye?
