Dermatologist recommendation for seb derm treatment in kolkata

I had been suffering from seborrheic dermatitis or excessive dandruff since the last 7-8 years and I have also lost a lot of hair in the process. My remaining hairs have just thinned out to the extent that my scalp is easily visible now.

So any recommendation of a dermatologist with whom you've had a great experience with or someone who you know is really good at treating this condition would be of great help. I'm 24M.
