Talk to Dermatologist on Dermatologist

Actually I am getting this allergy patches on my face. pics attached. history starts when 2 years back I got joindus and dengue together so after that I had severe hair fall and went to doc and he helped with the dandruff and Alhamdulillah by the time it cured and have some hairs left in my head. and using oil for growth. but patches on face are not cured and using diff medicated shampos to help cure it. It happens when beard grow and when I trim it there are redness and dandruff and these patches. sometimes on my shoulder and chest too. Can you help me with this issue. thanks
