One morning your hair is smooth, shiny and behaving itself. The next morning, it is frizzy, flat, greasy or somehow all four at once. No, your hair has not suddenly developed an attitude. The weather may be partly responsible. Hair responds to its surroundings. Humidity can make strands swell and become frizzy, while dry weather can leave them rough, brittle and desperate for moisture. Heat can increase sweat and oil on the scalp, while cold and windy conditions can make the lengths feel particularly dry. The trick is not to have a completely different shelf of products for every season. It is to understand what your hair needs when the environment changes.
