Fresh Flowers that work well in Wedding Hair:
Dendrobium orchids, Cymbidium Orchids (these flowers can hold up pretty good in wedding hair and last through the ceremony and photos but no there are really no fresh flowers that will hold up the entire wedding day...)
Here is me adding some flowers to my curly-headed sister's hair:
Fresh Flowers that work okay in Wedding Hair:
Gardenias, Mokara Orchids, Phaleanopsis Orchids (all of these flowers are very delicate, so your stylist must secure them without breaking or bruising them. It is good to have a second flower to change out later in the day.
Fresh Flowers to Avoid in Wedding Hair (get a silk or fabric version instead):
Roses, Garden Roses, Peonies, Dahlias (silk or handmade fabric versions would be so much prettier and will last all day. I always advise my clients against using these in their fresh form for hair...)
