Is there such thing as WAVY human hair extensions, or are they all synthetic?

I really want some decent wavy human hair extensions but the ones ive seen are all thin and synthetic and cheap.. where as im prepared to pay alot of money for really long, thick human hair ones? any help?Is there such thing as WAVY human hair extensions, or are they all synthetic?
They do have wavy hair extensions that are real. The hair extensions with real hair are a bit more expensive, but if you pick the right one and use them correctly, you will look beautiful! Sally Hansen has the best selection I've seen, so try one of those stores. Hair salons sometimes have them, but it's usually the hair salons that are super expensive - which means the hair extensions would be expensive. Hope I helped!:)Is there such thing as WAVY human hair extensions, or are they all synthetic?
Well you could get a perm, but if you want extensions i would suggest going to Sally's or a good store for cosmetices.
