This season is the most difficult for hair, yes hair falls the maximum in rains! There is a lot of moisture in air during rains, that makes hair oily and sticky. It also gets dandruff. The best you can do is daily wash & short haircuts. Short hair is always easy to maintain. Henna also works well for hair in this weather. Make a paste of henna and water and apply on hair for 10 minutes. Avoid conditioners and spa treatments. use clarifying or normal hair shampoo. Avoid sticky styling products. Keep scalp clean , nothing greasy on it can get you dandruff. If your hair gets wet in rain , wash it fast. Also the most important is to dry up hair fast after shampoo with a dryer. Natural drying of hair concept is wrong for this season.
