My 8 and 3 years old sons have terrible ringworms on their heads. i have tried covarex and antibacterial soaps but nothing works. i cut their hair at home and i use methylated spirit to sanitise the clippers after each use. but the problem persisit?

See the Dr: Your children need to be seen by their Dr, so that they can be examined and treated. The treatment is important because the problem will not be resolved without long term (up to 10 weeks) prescription oral antifungal treatment. Over the counter meds will not work on scalp ringworm. Without treatment the ringworm (which is actually a fungus) will continue to spread.
