When 'Tasha used to do my hands and feet, she would start me off with a self-heating finger soak of lotion and a self-heating foot pan of some kind of conditioning solution. Then she would give me a massage from fingertips to elbows. Then I got my cuticles trimmed back and my nails squared off and painted (I like polish, the flashier the better). Then she would start on my feet, and do the same --- ah, the foot and calf massages! Yes, 'Tasha rocked!
Of course, that sweet indulgence set me back $45 every month ... but it was durn clean fun!
I don't know that 'Tasha ever nicked me ... but I'm with Wneighbor ... you should have taken the teacher aside and pointed out his mistake! He's there to learn, hon, not to give you a nasty li'l infectable boo-boo!
Now you need to show us the haircut!
