hi i've never had a problem with dandruff except now embarrassingly i suddenly have a lot. I think its because ive been studying pretty intensely with exams and tho im obviously still showering every day i just tied my hair up every day and coconut oiled and washed it once a week (i usually wash every other day). I think this lack of washing has caused the dandruff. Will just going back to my normal washing routine fix it or do I need medicated products now?
