Answer

Shampoo and oral antimycotic therapy have been advocated for eradication of the carrier state. Studies have shown that most children who received griseofulvin plus biweekly shampooing with 2.5% selenium sulfide were negative for fungi on scalp culture after 2 weeks. Shampoo containing povidone-iodine has been shown to be more effective in producing negative cultures than shampoos containing econazole and selenium sulfide and than Johnson's Baby Shampoo. Therapeutic shampoos are applied twice weekly for 15 minutes for 4 consecutive weeks. Both povidone-iodine and selenium shampoos require further clinical study for the control of fungal spore loads in infected children and asymptomatic carriers.
