Don't Blow-dry Your Hair When It's Wet
Say what? Isn't that what a hairdryer's for, you ask? Well, kind of. The general rule of thumb is to wait for your hair to be about 80 percent dry before you pull out the dryer, and that's extra-important for long hair -- more heat exposure causes more damage. So, after you get out of the shower, pat (don't rub!) your hair with a towel, apply styling lotion and detangle your hair with a wide-tooth comb. Then hang out, get dressed, do your makeup, do whatever you need to do while your hair air dries. If you're crunched for time, go ahead and use medium heat to pre-dry your hair, but don't start the serious work until it's almost dry.
