In summer, the scalp becomes oilier, changing how often you should wash your hair.
Russian dermatologist Stefano Maria Serini told "El Economista" that washing frequency depends on scalp type.
Those with oily scalp should wash 5-6 times a week, while dry or normal scalp requires washing every 2-3 days.
The doctor emphasizes using mild, nourishing shampoos if you need to wash more often.
