thanks for posting your query.
you seem to have got a reaction to nizoral
shampoo since it was kept for longer than required.
you need to apply a steroid cream like mometasone
twice a day for a week.
also you take an antihistaminic like tab. allegra 180 mg once a day to bring down the inflammation.
if you dont start improving within a day you need to see your dermatologist
stop the nizoral shampoo. also the treatment of white spots
has to wait since its important for reaction to resolve.
you probably have pityriais versicolor which is a fungal infection
for which nizoral was given. with treatment too it takes 6 weeks for colour to come back.
you need to consult your dermatologist for further treatment.
