Doing anything to radically alter your appearance, like coloring your hair over four shades lighter (or darker), the evening before your nuptials needs a resonant “no”. You will still want your husband-to-be, your loved ones, and your guests to recognize you about the big event, right? Then it’s best to avoid making those intense changes. It is possible, however, dye your hair one or two hues from what you are wearing right now. It’s also a good idea to do it days prior to the big day so you will still have enough time to make adjustments and corrections. Most wedding expos showcase products and vendors with products you could try. But, you should always try new things out months before an important event and with good with caution. This applies to spray tans, too. Moderation is the answer.
