Couple of hair extension questions?

I am getting clip in hair extensions, and I heard the ones from Sally Beauty Supply (http://www.sallybeauty.com/sallybeauty.c... are really good. I am planning on getting the real hair clip in's because they're real hair.

I have thick, brown straight hair, btw.

1) Which extensions are best for me (length, color, etc.) A LINK WOULD BE GREAT!

2) Where do you clip them in?

Couple of hair extension questions?

i used to have sally's ones.

they are good - only if you look after them.

u need about 2 sets.

seperate your hair in half then clip them in..

and then put the other set underneath the 1st ones.

that turns out nice. xD
