What exactly are hair extensions? how much do they cost in the U.K?

It's like fake hair to make your hair seem longer. I want some myself too. As the girl said, you can buy them at Sally's Beauty Supply in any color you want. You can get them professionally done too. What I've heard is, that it's about more than $40 to get them professionally done. Here are some pictures of extensions :

What exactly are hair extensions? how much do they cost in the U.K?

Basically extra strips of hair that can be any colour you like and can be glued or clipped through out your own hair to make your hair look longer or to make your hair look thicker/fuller. You can but them from "SALLYS" in the u.k, depends if your getting alot of extentions or just a few, What colour or how long they are so i couldnt tell you an exact price, Call up 118 118 and ask for the nearest "SALLYS" hair and beauty shop and they will give you the number then ring them and tell them what you would want and they can give you a round about price.. GOOD LUCK!! xBx
