In order to take care of the sores on the back of your head, it is important to know what causes them in the first place. An abundance of dandruff is well-known to cause head sores. If this is the case with you, then you would need to take care of the dandruff and then the sores would go away by themselves. Sometimes, the presence of ringworms is also a cause of sores on the scalp. In order to determine or eliminate this, you would need a medical examination. Ringworm is a fungal infection that can be taken care of medically in as little as a three day cycle of medication.
The cause of sores on your scalp could also be a skin condition such as eczema or psoriases. Both of these are commonly occurring problems which can be taken care of with a simple basic course of medication. Although it needs to be said here that psoriases may not always be found to be treatable with allopathic medication. The best routes of treatment for this problem would be to turn to Ayurveda or homeopathy, as both these streams of science offer a permanent and irreversible cure for the disease. You should also determine that you are not sitting or lying down on a surface that could be a possible cause of these sores.
