I will give you my honest opinion. I worked in a professional hair salon for 4 years. I let them put extensions in my hair 1 time. If you've never had them before, I wouldn't recommend putting them in right before the wedding. If possible I would do a lot of research, find a reputable salon, and have them put in 10 or 15,(several months before the wedding) just so you can see how you like them, how your hair takes to them, how hard it is to hide them ect. The biggest problem I had with them was that they tend to tangle near the root, and tend to "stand out" from regular hair. The ones I had were all 100% human hair, and I still wasn't crazy about them. I BUT, I also have "weird" hair, so your hair may take to them juuust fine. You may love them, and have no problems at all, but I would start with a few before doing your whole head.
