I need help with a new hairstyle and dry hair on the bottom?

okk should i cut my hair a little bit because the bottom of my hair is so dry and ugly because of the flat iron so would i look good with shorter hair? and what hair style should i do . ALSO how much does it cost to put real hair extensions on? thanks my hair is actually a bit longer. a href="http://i98.photobucket.com/albums/l268/glendita10/IMG00097.jpg" rel="nofollow"http://i98.photobucket.com/albums/l268/g…/a
