Advice & Help please

Hi all,

Im new to this site, a freind recommended me! Iv got a few questions to ask & was hoping some of you might be able to answer them. I am thinking of getting hair extensions as I have shoulder length hair and really want long hair! Iv heard so many things about extensions - good & bad. Im really confused. I dont want them to ruin my natural hair & iv even been told my hair will fall out?!

I just would like to know whats the best way of having them done? Iv heard of so many methods & really dont have a clue?

Also do they give you headaches & make your hair itch? How hard is it to maintain them? I normally wash my hair every day or every other day would this be a problem?

Thanks x
