You probably have a long checklist of beauty-related errands to complete leading up to your wedding, like booking your hair [1] and makeup artists, and ensuring your skin looks glowing [2] on your big day. Unfortunately, many brides make mistakes when trying out treatments and products for the first time, and end up with less than desirable results on their wedding day. The to do-list [3] might seem overwhelming, but luckily, we're here to help.

We've consulted hairstylist Linet Keshishian [4] and dermatologist Deborah Jaliman [5] to ensure you don't make any mistakes along the way and look your very best as you walk down the aisle. Ahead, check out the common mistakes brides make so you can avoid these mishaps.

Colouring Your Hair

While a colour refresh might be a good idea before your big day, make sure you don't do it (or get a hue you haven't had before) too close to the date. "[This] won't leave any time to change or correct any tones or hues don't like," said celebrity hairstylist Linet Keshishian. If you'd like to change the colour of your hair do it subtly over a few months. "A gradual colour change is safer and easier to get adjusted to," Keshishian said.

Not Investing in a Trial Hair Appointment

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."

Not Considering Your Dress

Chances are, you spent a lot of money on your wedding dress and you probably want to show it off. Making sure that your hairstylist knows what it looks like is essential. "Discuss the neckline of your dress and show pics of it to your stylist to get the best advice on what will look best," Keshishian said.

Trying New Products Near Your Wedding Day

According to dermatologist Deborah Jaliman, it's best to stick to a routine of consistent products leading up to your wedding day, rather than trying anything new. "If you have an allergic reaction or irritation from that product you can turn red and swollen and that would be a problem right before the wedding." she said. "For people that are acne prone I've seen brides get bad breakouts from new products."

Getting Fillers Near Your Wedding Day

It's important to remember that when you get injections, you can potentially be a little bruised afterward. "I recommend that they do this procedure one month before the wedding so that it can be tweaked if necessary and it has time to settle in and if bruises do occur they have time to resolve," Jaliman said.
