Probably not. Dandruff is a finicky condition that often comes and goes; the frequency and severity of symptoms vary according to a number of factors. You may notice that your flakes tend to ease up during the warmer months, when the skin on your scalp is less dry. Stress -- or the lack of it -- can also affect your dandruff levels.
Year-round, the best way to keep your hair and scalp healthy and flake-free is daily washing. Use a gentle shampoo if you’re not having symptoms, and alternate it with a shampoo specially formulated for dandruff if the flaking and itching recur.
Keeping stress levels in check is another good way to keep flakes at bay. Exercise, meditation and taking time to do things you enjoy can also help.
