Long ago, when I started using Miracle-Mineral-Supplement , I was using apple cider vinegar to activate it. Then I read where some fungus loves the stuff. Then others said no. So, I decided that since it is controversial, I would change to lime. Lime is more acid anyway; so it should be a little stronger than the vinegar.
I believe that Miracle-Mineral-Supplement will lighten your hair. Turn it blond. I assume you mean that you will use it after it is activated. Straight Miracle-Mineral-Supplement would be very strong. So watch for blond spots where you apply the MMS to your head.
