1) Choose a ceramic or tourmaline flat iron. A titanium flat iron isn’t for daily use and is best for professional use. Ceramic flat irons are best known for heating up quickly and evenly distributing heat across both iron plates. Tourmaline flat irons or known to aid in the reduction of frizz, the buffer the hair and add shine, through the infusion of negative ions.
2) Make sure to use a heat protectant on your hair. You will be applying direct heat and you want your hair to be protected from the heat and you want your curls to last as long as possible.
3) When curling the hair let your iron do most of the work. No need to over use your wrist. That coupled with typing and other activities, can exhaust your wrist and lead to carpal tunnel. Simply flip the hair over the iron and pill downward. The slower you pull down, the more curl added to the hair.
