since a month ago I noticed a red rash on the back of the neck after my usual hair cut. it is not itchy . and not flaky. The skin looks normal but red. I have used the anti fungal cream but it does not go away, the redness is a bit less after one month using the cream. Any Idea what it could be? I have no allergy. male . 35 years. the first time seeing this.
Hi, It could be a form of eczema e.g. either seborrhea dermatitis or psoriasis. The back of scalp and neck are common sites for these conditions.  If I was the treating doctor, I would recommend that you use a moderately potent topical steroid e.g. Mometasone Furnace cream or Triamcinolone Acetone, twice daily for a few days.  Hope I have answered your query. Let me know if I can assist you further.
