i just got rid of ringworm (on my face, no less). i used lamisil at cream. the directions said apply once daily, but i doubled up, morning and evening. before i applied it i washed my face with head and shoulders (i read the active ingredient, pyrithione zinc, was supposed to help also). it took about a week for it to go away, and i don[t really notice any discoloration or anything.
for maximum embarrassment at the pharmacy, get the package of lamisil thats for jock itch, not athletes foot. its the exact same shit except for the look of disgust you'll get from the cashier.
