The Babyliss Pro Nano is an excellent choice for short to medium-length fine hair. Fine hair must be treated with extreme care. The use of titanium plates on this flat iron helps protect your hair from burning. And thanks to its ultra slim design, it is also great for curling the hair.  Although the Babyliss Pro Nano's heat settings go all the way up to 450 degrees, lower heat settings are available to cater to fine hair.
