To the AC asking if MMS bleaches the hair, I would say no, from experience. I have recently bathed in it twice, submerging my hair into the water, and it didn't have any effect on my hair.

I recently had a deep cut on my arm from a dog's claw. I was using an H202 gel on it, it helped a little, then began to have signs of infection, the color, and redness spreading.

I finally took the plunge, four drops + citric mixture internally, with 20 drops +citric mixture in bathwater. Afterwards made up a solution that I sprayed on directly, for three days per instructions. It did get better, but the redness around the gash seemed to continue spreading, along with my arm aching.
I repeated the above bath but increased it to 30 drops + citric mixture with 1/4 cup DMSO and four drops MMS + citric mixture. That did the trick! By the second day all the redness was gone. Withing a week, the skin is smooth.
