This is a sign of lack of moisture in the hair. Silicone based products keep moisture out when hair needs it the most. Try frequent deep conditioning treatments with panthenol enriched products like our regular conditioner. For styling, apply Robert Craig's Pomade while hair is still damp. The pomade helps hair retain necessary moisture while blodrying/straightening and leaves a protective barrier between the hair and humidity. If your hair is sufficiently moisturized, it is less apt to absorb moisture from the air.
