Dry hair is a common condition characterized by a lack of moisture in the hair strands. This can result in hair that feels rough, brittle, and prone to breakage. Factors contributing to dry hair include environmental conditions, such as cold weather or low humidity, as well as excessive use of heat styling tools and harsh hair products. To improve dry hair, it is essential to use moisturizing shampoos and conditioners that contain hydrating ingredients like argan oil or shea butter. Regular deep conditioning treatments can also help restore moisture. Additionally, minimizing heat exposure and protecting hair from environmental stressors can prevent further dryness.
