Do not style hair with a flat iron while it is still wet to avoid steam damage. Wet hair produces a boiling effect that boils the center of a hair shaft. This causes a break in the walls of the medulla and produces bubbles in the shaft that decreases shine. Hair becomes rough, dry and is more easily snapped off when it is styled while wet.
Using a flat iron daily causes frizzy hair of differing lengths because of hair breakage. Change the flat iron periodically when there is buildup on the plates or the surface of the plate becomes sticky. This buildup and stickiness is caused by burned hair cells and it causes more damage to hair if used for too long.
