I was wondering if anyone has bleached the front of the lace (SFS lace) with success? I run into a problem of discoloration, especially when I sweat in the summer. This results in a line showing along the border of the lace on my forehead. If I can die it back to neutral color, I can extend the life of my units. If you've had success, what product(s) do you use to achieve this?

Thanks in advance.
