There is a minute amount of sodium hydroxide formed when doing the blend, and yes it does continue to act on the follicle for a short period of time (maybe an hour or so). I don’t believe it will remain static for a significant amount of time.
Although nobody has even done a test on a live person, my guess is that the lye remains in the skin for no more than a few seconds (if that). The body quickly balances the Ph of lye. After all, the lye is in direct contact with the “moving” blood.
I’m hoping our resident chemist here will offer an opinion. I mean “Brenton.”
