The most common reason for limb lackluster hair is the acute lack of moisture. Another sign of too little moisture in your hair is static electricity. While a moisture content of 10 % is sufficient for the skin, hair needs 15 to 17 % water.
Moisture Draining Factors
Dry heat deprives hair of moisture. When your hair is dry already daily blow-drying and the frequent use of heated rollers and flat irons will quickly turn your hair and scalp desert-dry. You should therefore use heat-styling tools sparingly and keep the blow-dryer settings on low-heat and full air flow. During visits to the sauna in winter you should be sure to wrap a towel around your hair to protect it from the dry heat (up to 100 °C or 212 °F). Protection against moisture loss works even better after you have worked a conditioning cure through your hair. The same applies to spending time at the beach. Wearing a hat, cap or bandana protects your hair from extreme moisture loss and the resulting frizzy hair. Keeping your hair properly moisturized is particularly important for color-treated or permed hair.
Sources of Moisture for Your Hair
Water is a special medium. Drinking it provides the needed water to sustain the body’s metabolic processes and to support the cell structures. If used externally for a bath, shower or shampoo, water can drain water from skin and hair. This sounds paradoxical but it is true. It is therefore important to use moisturizing hair care shampoos. Among the most efficient moisturizing and conditioning agents in shampoos and hair rinses are Aloe vera, glycerol, panthenol as well as silk and wheat proteins. Thanks to their molecular structures, these active agents bind moisture inside the hair or coat each individual hair with a protective film. This keeps the hair smooth and seals the cuticles. The sealing effect allows the hair to better retain water.
