Flat Irons and PregnancyQ: Hi. Is it safe to use flat irons for the hair during pregnancy?
A: Of course. Most of the problems encountered by pregnant women with styling the hair come as a result of chemical services, and the way medications and hormones will change the way the hair responds to those chemical services.
Flat irons, curling irons, hot rollers and blow dryers allow the hair to be styled by making physical changes in the hair, and therefore are less affected by chemical changes in the body.
You see, with a perm or chemical straightener, the hair is made to curl (or hang straight) because the chemicals used break the disulfide bonds in the hair (the chemical side bonds) and reform them into the desired new formation. However, with a heat appliance, the tools break the physical side bonds (the salt and hydrogen bonds) of the hair by using heat. When the hair cools again, the bonds reform in the new, desired shape, which allows the hair to hold the curl or stay straight as intended.
