Follow-up: 50/50 hydrogen peroxide & water on hair transplant recipient area. Toxic?

I am resubmitting a former question to reclarify things. I misted a 50/50 solution of hydrogen peroxide & water to recipient area on day 5 after hair transplant (I did this to soften crusts). Rinsed and shampooed afterward. Then I read somewhere that this could be toxic. I am NOT worried about crusts anymore (they will go away eventually anyway), I AM Worried.... Did this poison and destroy the Grafts? I appreciate the response on Best way to get rid of crusting; but "Did I do damage from mist?"
