I really do hate hearing myself on camera but I'm doing this for the good of my blog followers - so you have to suffer with me...sorry!!
I hope these tutorial are helpful to you who are trying to learn. The key to doing it though is PRACTICE. I've had lots of practice to perfect it & so it's fast & easy for me. You'll just get better & better each time you do it and you learn your own mistakes along the way so don't feel discouraged!!
Okay - I still have had a lot of questions about how I do the quick messy buns. My husband had today off so I thought it was a perfect time to do the video tutorial. Adde was really bugged we had to pause her show so it wasn't blasting in the back ground. She really isn't normally like this - but now you can my child does not sit perfectly still 100% for me either:) & I really don't like listening to myself on video (who does) so sorry!! Hope this helps out those who still are questioning it.
I scrunch up all of the hair into a ball with my hands.
Wrap your rubber band around it. I wrap the elastic twice so it is VERY easy to come out (it really isn't hard to get out). Now that her hair is getting so long, I usually have to do 2 different rubberbands around the messy bun so it stays close together & isn't so HUGE. But if your girlie's isn't as long, you should just need one.
Tug at some strands to make the messy bun look even.
Spray to hold & that's it!! Easy, right?
I do do it differently once in awhile, but this is what I usually resort to. If you have a way you do your messy buns & would like to share with all of us, email me step by step instructions & we'll post it for everyone to see.
A lot of moms have asked how I get Adde to stay still while doing her hair. I do her hair on my bed & she watches tv while I do her it. Or if you prefer the mirror, give her toys & books to play with or even snacks while you do her hair.
Do hair while is damp. Pull hair into a pony tail. I DID NOT part the hair at all, I pulled it all straight back. Grab a piece from the pony tail.
Loop that piece around & pin it. Do this all the way around the pony.
This is what it looks like once you have gone all the way around. See that extra piece hanging out from pinning your pieces? Just tuck that under the bun & pin it. 
Spread each piece just so it looks more like one bun, instead of being able to see each piece pinned. Spray to hold. Add a cute head band or flower clip on the side of bun. 
So - I'm just gonna try my best, with one hand to show how to do these. I'm not sure what to call them, so we'll just pretend and call them tuck-under knots. You can do SO much with these. You could even do this on short hair put them into just half way up pigtails or just leave all the hair down.
Start by sectioning off the hair that you want to do the tuck-under knot on. I find the smaller the section, the better.
I get the end of my comb & divide it right down the middle of the section. By doing this, you won't be pulling lots of little strands on the way, or hurting her little head.
Now, just tuck the piece of hair under, where you divided the hair in half.
Pull the hair completely through, and this is what it looks like!! Super easy, right?
Now, pull the hair tight, so this is the finished product!!
Do the exact same thing to add another tuck under knot
This looks like the top, but it's the bottom. Do the exact same thing as the top, but pull them through the OPPOSITE way, so it looks like the are supposed to be going up
Put the remainder of the hair into pigtails. You could either leave them straight, pull just half way, or do the messy bun. I zigzagged the part, but you could also do it straight.
To do a messy bun look, after you have pulled the hair just half way through, scrunch up the ponytail & put a rubberband to hold it in place. Spray the bun a little so it will hold better & you may have to pull on some pieces to make it look more symmetrical.
And there you have it. You could even do the twist under knots all the way down, in a straight row, instead of splitting them. That looks really cute too. 
Do you remember fish braids? I used to love them. But they really do take forever to do, with all the small pieces you add to it. So I did it this way - so it is much quicker.
Start by making your pigtails. Then divide one side of the pigtail in half.
From the right side of the half, grab a small piece. Grab it from the very back of that half. This is where you will always grab your pieces from. You'll see as you go, that if you do not, then you'll have a big chunk you'll need to bring forward & you want small pieces.
Take that small piece and take it over to the left side.
Now, grab a small piece from the left side (same way - back, top)
Stop wherever you would like to and put a rubberband to hold it.
Go down aways & add another rubberband, so there is no braid in this area. Then start the fish braid over again.
Go all the way down until you reach the ends of the hair. Do both sides the same.
