While it might seem like a waste of money to get your hair done before your big day just to see how it will look, a couple of trials are well worth the investment. "Leaving the styling for the big day may be too much of a surprise and possibly a disaster," Keshishian said. Knowing exactly how your hair will look on your big day will give you one less thing to worry about. "Hair trials will give you peace of mind and [ensure you get] the exact styling you want on your special day with your desired head piece and or veil."
