I've occasionally gotten spots like that, but I don't know what causes them.
Is there a chance that the hair in that region is being pulled in a direction it doesn't want to go? I certainly get sore areas when I do a crown braid, for example, on the side where the hair is going up instead of down. That usually subsides with a day and a washing, though. Perhaps some sort of anti-irritation cream or an antifungal would help, but I think I'll wait to see if anyone else has ideas before suggesting you try that.
With regard to the dry hair, I see your location listed as Egypt. I know there's a lot of variation, but is the air very dry where you live, or dusty or full of sea salt? I suspect any of these would really increase the rate that hair dries out. Unfortunately, humectants such as the honey in SMTs aren't particularly effective in arid, drying conditions. They attract moisture to themselves -- in normal to humid places, that tends to mean that they draw moisture out of the air and hold it near the hair. In dry conditions unfortunately, they tend to draw moisture from the hair and disperse it to the air. If you can mist your hair with water regularly, that should help the moisture a bit. Otherwise, I think the best thing I can suggest is to oil your hair as much as you can stand. I find applying oil to wet hair gives nice results, but different people have different preferences.
