You know the drill with beauty safety:
Don't try to bleach your hair all by yourself.
Don't use liquid liner on the inside of your lid.
And if you choose to iron your hair, be careful, because it could all burn off.
Of course, there are ways to avoid that - primarily, using a really good straightening iron.
The girls in our office swear by the new Izunami One-Inch styler, with a thin body to get strands close to your head, and a tourmaline base that heats hair without frying it.
At $150, it's definitely an investment, but straightening addicts know, there's really no price you can put on keeping your hair shiny, easy... and intact!
