Read this in HINDI. I am a 26-year old girl with unruly hair. I visit the salon and get my hair blow dried twice A week as my hair gets very unmanageable otherwise. My friends tell me I am damaging my hair! Are they right? Can blow drying my hair so often cause damage? Nothing can beat the feeling of walking out of a salon with fresh and flawless blow dried hair. But it is true that blow drying your hair too often can damage your locks. The heat treatment can make the cuticles of your hair dry and brittle.
