Hi . I replied to a comment from you about this elsewhere, but I will respond here as well in case you didn't see it. Personally, I have not heard of Hep C causing hair to turn transparent and I couldn't find any research to support it. That doesn't mean it's not possible. Hair doesn't really turn transparent though. It can appear transparent though as we age, producing less pigment. The lack of pigment can turn hair gray, white or silver and, to some people, those colors can seem transparent. I hope this helps. Wishing you the best. - Lori (Team Member)
