Lea Michele, the star of my fav new show Glee, puts her hair through the ringer each and every day. Lea Michele’s hair routine starts with blow drying, then straightening with an iron, and then adding extensions! My gosh that is a daily routine. What is her secret to keeping her hair healthy? Use protection on your hair. Yes like a thermal protector. It is so important to use a thermal protector on your hair daily to help fight the effects of heat damage. This is even if you just use a hair dryer. I use the CHI 44 Iron Guard Thermal Protector and I love it since it is light and doesn’t leave a nasty residue on my hair.
