I'd try 5%.
I think your eyes may be getting bedazzled by the hair fibers reacting differently between your eyeballs. Close one eye. . . then the other while your looking at it. Often things with fine detail like that really draw your eye and make you think they are far more intense than they really are. Also try photographing it in a well lit room without any flash. I think you'll be surprised.
My daughter has a scarf made out of that super shiny/soft fiber material. Crazy stuff.
