Scalp ringworm is a fungal infection on the scalp and appears as one or more scaly patches of skin just above the hair line and may have what looks like small black dots. The scaly patches can be red or gray in color and can be very painful. Scalp ringworm is very contagious and can be passed from person-to-person or from pet-to-human. There are several home remedies available that are easy to make and very inexpensive.
Slices of raw papaya rubbed over the ringworm or a paste made of the papaya applied directly to the ringworm is very effective in killing ringworm and keeping it from spreading. Another remedy that will kill the ringworm and stop it from spreading is a paste of ground mustard seed with a little water applied directly to the ringworm twice a day. The herb butea, when ground to a powder and mixed with enough lime to make a paste applied to the ringworm twice a day, will kill the ringworm and keep it from spreading.
Your doctor may recommend using a medicated shampoo containing selenium sulfide that can be used several times a week and should be gently lathered into the scalp and left on the hair for about 5 minutes before rinsing off. When shampooing, the hair may come out in splotches, but after the ringworm is gone, it will grow back.
In extreme cases, scalp ringworm can cause a very painful reaction called kerion, which is caused by the person infected having a serious reaction to the ringworm fungus. Kerion appears as swelling lesions on the scalp that are filled with pus; when the pus dries, it leaves a yellow scab to form on the scalp. If the ringworm has progressed to this stage, a doctor should be consulted immediately. When this condition exists, the hair will fall out or can be easily pulled out and can lead to scaring and permanent baldness.
