"Stretching" Hair

I've heard of a technique called stretching and was wondering how is it done. Is it blow drying your hair to add length or are there other methods? Once the hair is stretched, do you re-wet your hair to style in braid outs, bantu knot outs, etc., (would seem like it would defeat the purpose). I'm a bit confused on the process and how the hair is styled afterwards.

Advice and/or suggestions welcomed.

Thanks.

Thanks ChrsLvsBks! I'm going to give it a try this weekend.

I usally stretch my hair out after taking down my twist-outs/twist n curl with a hand held blow dryer! I tend to have lots of shrinkage, and to get length, its a must that I stretch it out so I can have full, big hair! This past weekend, I did CurlyNikki's routine by twisting, then braiding for more stretch, and MAN OH MAN, I looooooved it! I could actually tell that my hair has grown sooo much because it was stretched out really good, but still had the curl factor that I wanted! So from now on, I will definitely be doing the twist-n-curl/braid out routine for stretching! Love it!

I twist while wet, let it dry and then retwist while dry.

Okay Ladies,

I re-twisted my dry hair last night. Overslept this morning and hurriedly got ready for work. I received many complements. Thanks to all of you!!
