Straight, shiny and smooth hair has always been in trend as it looks good on any face type. Also, straight hair can be worn free flowing or styled in numerous ways.
People who are not blessed with naturally straight hair often turn to chemical treatments to get rid of unruly waves and curls. Many beauty salons offer hair-straightening services with immediate results. The finished look lasts for a limited time, perhaps for a year.
