The only cure for lichen simplex chronicus is to avoid scratching. Lichen simplex chronicus which I call as Scratch Dermatitis is the direct result of repeated friction to the skin. There are no parasites or fungi to be expected in this any way. One may use any cortisone containing ointment or cream to help the feeling of itching but this should only be considered a help and not a cure. The only cure lies in not scratching.
