I am fed up with my straight hair and I am looking forward to curl them. I tried them to curl once with hair rollers but they did not seem to work on my hair. This time I have bought hair curlers which I think are better than the early one. Like earlier I donât want to waste my time on trying so I want to know how I can make my hair look curly with the help of the curlers. For how much time I need to keep them in my hair? Do I need a blower to blow on the curlers?
