diy wedding hair. Practice. I was going for a very simple look. Try following the same timeline as the wedding day — do your hair in the morning, then see how it wears throughout the day. That way, you can troubleshoot any problems. Also, make sure that you practice every detail of the hairstyle — including the curls. I made the mistake of not testing curling my cousin Rachel's hair, and the curls practically fell out before the ceremony (sorry, Rachel). At least the top still looked good!
