How to Plan and Start a Wedding Beauty Regimen

Health: Stick to healthy eating habits.

You might think you're "getting a jumpstart" on wedding weight loss if you drastically cut calories and follow every cleanse you see on Instagram.

In reality, you're setting yourself up for trouble, the extra-pounds kind of trouble. "I've seen these deprivation crash diets backfire time and time again," says registered dietician Brooke Alpert.

"Because you're basically starving yourself, you're going to breakdown and binge, regaining the weight you lost and feeling bad about yourself."

Not to mention how cranky and miserable you'll be in this highly social period of your life.

To stay sane — and svelte — Alpert recommends aiming to have a healthy (sugar-free!) meal or snack every three to four hours. When: 1 year out

Hair: Shampoo less often (yes, really).As great as H20 is for you internally (it hydrates and debloats, so drink up), when it comes to hair, water won't do those pricey highlights or rich faux brunette any favors. "Over-shampooing lifts, dulls, and fades hair color," says Dorram. "I always suggest shampooing no more than three to four times a week. The best is to rinse hair and use a mild detangler in between shampoos." When you do opt to suds up, do it with a gentle, color-loving shampoo like Leonor Greyl Bain Vitalisant-B Shampoo ($47). When: 6 months out

Teeth: Invest in tooth whitening.If you want to amp up your smile, consider splurging on professional grade tooth whitening. These days a whitening treatment can be done in-office in under 1 hour and comes with convenient take-home whitening trays, depending on the level of stains. You can easily whiten your 4 o 6 shades and results last for up to a year. If you go the at-home route, we recommend Crest 3D White Luxe Whitestrips ($35), which can whiten teeth up to 3 shades. When: 1 month out
