You shouldnt get them now, they would either be to low or have falen down by november. Try to get them like weeks before your wedding.How long do hair extentions last?
if you're getting clip on extentions(jessica simpson) it's smart to get the human hair if you want to use them for a while .. they are 500 on www.hsn.com but about $230.00 on ebay(: if you're just using them for a month, jessica simpson sells synthetic extentions in curly, straight, short, long, layered, and even a bun on hsn and they're also probably on ebay ... as for real extentions i'd think the same would go, so if you're doing the real thing, get human hair because they will last longer(: congrats on your wedding
Have your hair extension two weeks before your wedding.
extension usually last about 2 months so i would recommend getting them like 2-3 weeks advance of the wedding...but it also depends on what kind of extensions your getting...if your getting the fusion ones which are the best. the weave, or clip ons...try going to a few places to see which ones would be better for you...they range from different prices, fusions are the most expensive and then it goes down hill..but the price also depends on the city...im from Chicago so i wanted to get the fusion ones and they were going to cost me over a grand but they told me that guaranteed me that they would last more then 3 months.. good luck getting them!! and congratulations!!!!!
