No doubt that it's dangerous!  When I used it, I used to somehow get
droplets splattered onto my skin, with the resulting little pure-white
spots.  Never noticed the splatters when they happened, but they always
seemed to.  The concentrated peroxide should never be used without adequate
protective equipment, and I'd say a face shield would be included in that
equipment.
 
Liz--you wouldn't use the concentrated peroxide on hair!  You'd lose hair,
scalp and all, I suspect.  I'd guess they use some dilution that's stronger
than 3% but way more dilute than 30%.
 
I'm a bit skeptical about the ability of charcoal to adsorb the color from
wax, but it might work.  Anybody ever try it?
