I have pretty thin hair that doesn't hold a curl very well or long. I have never had extensions before but I think I want to for the wedding cause I'm afraid my hair will fall flat quickly. What is the best type of extensions to get? I am not looking to get it super long I just want to make sure my hair has volume and looks full and will hold curls longer. And how long before the wedding should I get the extensions put in? And how long do they usually last? Thanks in advance for your help and advice!
