I have a problem of scalp irritation which deteriorates after a go out and catching up dirt & pollution. I generally shampoo my hair after every 2 days to keep it clean, and dont even keep my hair oily for it to not attract dirt. Kindly advice on what should I do to get rid of this.
This may be a case of seborrheic dermatitis. The exact cause of seborrheic dermatitis is not well established however it has been associated with a yeast infection. I would suggest that you have scalp scrapings microscopically evaluated to ascertain if a fungal infection is present. Washing the scalp with medicated shampoo like selenium
sulfide twice a week may be able to help. In between , frequent and vigorous washing with regular shampoo may also be able to help. I would suggest you avoid prolonged exposure to heat
