Without more information on the ink itself and its content, I will simply can NOT participate in something potentially hazardous to health. Mark, I would suggest you pay or submit your ink to a reputable government agency or independent lab to certify that the content and chemical make up for your ink is safe. Without current government oversee on these type of chemicals used by practitioners, it is very concerning. Consumers must and should know what they are putting on their head is safe - period. This goes for all SMP. I like your procedure simply because it is permanent and no maintenance, but safety first.
