Sometime itching and after scraping become scar very tiny with blood. I always avoid oil to it. But used put oil sometime before wash. Most of my shampoo by shopnut. But while travelling use of head n shoulder is there. Now I have shaved of my hair on 22nd feb n then on 1st march after cutting short of my hair to shoulder length during last 5 years. When first shaved off red rashes were there and now only few are left . About 90% are gone. But why these few are remained????

Hi, It sounds like you have had a fungal infection or an autoimmune skin condition. These often cause patches over the skin and the scalp. They may be itchy, red, and cause some oozing. Usually, most fungal and autoimmune diseases are treated with steroids or with antifungals. The exact treatment varies based on the cause and the resistance to medication.  It is possible that the complete removal of the spots has not occurred because the treatment has not been completed, is ineffective, or because there is some resistance to treatment. Another reason may be that the spots or rash is unrelated or a side effect of the medication that you were using.  It would be a good idea to see a Dermatologist confirm if the spots are related to the older spots and if you are allergic to any of the medications that you were using.  Hope I have answered your query. Let me know if I can assist you further.
