Wind – Prolonged exposure to windy conditions dehydrates hair follicles and forces the cuticles to rub against each other and even tangle. When the wind is strong wear a hat or scarf for protection. Do the same to protect hair from ultraviolet rays and smog.
Sun – The sun’s ultraviolet rays break down keratin protein in hair resulting in weaker, drier hair. Occasional exposure to the sunlight is fairly safe for normal healthy hair. However, chemically processed hair is more porous and particularly vulnerable to UV radiation. Over- exposure to the sun is not only harmful to skin but hair as well. Wear a hat to protect hair during extended exposure.
