Is cold weather harmful to hair in winter? Need protection? I once lost my hair. Please, thank you.

In winter, the climate is cold and the air is dry. It is necessary to reduce the number of shampoos and protect your hair by massaging your scalp. The method of massaging the scalp is simple, standing, sitting and lying down. When massaging, separate the five fingers of the left hand or the right hand, gently massage with the fingertips, back and forth, left and right, and finally massage in circles. Once in the morning and once in the evening, 5~ 10 group each time. Multi-purpose wooden comb for combing hair
