Have you ever gone in for a trim and ended up getting a lot more hair cut off than you wanted? It certainly has happened to us. And while the unwanted growing-out period was frustrating, we always thought it could be worse — it could have happened right before our wedding.Well, a few of us Spa Week staffers got engaged this year, and like so many women, our wedding beauty prep began with growing out our hair. Long, tousled waves work so well with wedding gowns, and long hair gives you more options for updos, too. Needless to say, the thought of anyone bringing scissors anywhere near our hair right now just gives us the shivers. But there’s no reason to worry. Celebrity stylist Sally Hershberger shared some tips for brides-to-be (or anyone looking for longer, stronger hair in 2013). Here’s what to do to ensure that the period between now and your big day goes smoothly: 1. Start to use hair-strengthening products if you plan to grow yours out. Sally’s pick: Hyper Hydration Super Keratin Spray. 2. Book a wedding hairdresser at least 8 weeks before your big day. Bring a photo of your dress to the trial! 3. Leave at least a 2-week buffer between your last cut/color appointment and your wedding, in case you need to fix any mishaps. 4. Planning on an up-do? Don’t wash your hair the day-of. Wash it the day before, as freshly-conditioned hair is too clean/slick to hold a style securely. 5. Less is more when it comes to accessories. Don’t take away from a beautiful dress (and face!) with too much bling on your hair.
