###Human: I have itchy scalp. Is it folliculitis? ###Assistant: Hi. I have checked your photos (attachments removed to protect patient identity). It is better you go for haircut and shave or trim beard. It may be due to folliculitis or fungal infection by the description. You can get it examined by a doctor or dermatologist for physical evaluation and diagnosis. You need not worry about spreading infection to others. You can use separate trimmer for yourself or get it done by a barber with separate trimmer. The disinfection method you are following should be fine. You can use topical antibiotic cream like Mupirocin (T-bact) if pus filled lesions are present. Do not worry about transmission of diseases. You can wash your hands with soap and water after using washroom. The lesion on elbow appears to be due to dryness. You can use moisturizing soap or Cetaphil cleanser. Apply moisturizing cream like Ponds or Cetraben cream. Main ingredients of this cream are (White soft paraffin and Light Liquid paraffin). For further information consult a dermatologist online -->
