Hair Extensions only in My bangs??

I don't think they look bad at all! and you got a cute dog :) One thing I did think of was that sometimes I have an easier job straightening them using a blow-dryer and hitting them at the roots, rather than a flat iron. 

No vitamins can cause hair growth, but having a balanced diet and being healthy will allow your hair to grow at its optimal natural rate, if that makes sense. I wouldn't reccement going on any type of vitamin or supplement other than normal one-a-day types with out talking to a doctor first as there are risks involved- this is info comming right out of my dermatologists mouth too btw. prenatal vitamins do have ingredients that benefit the skin and hair, however for some people they contain dangersouly high levels of iron and other nutrients.

to be honest with ya, I'm growing out my bangs too - I had a bored day about 2 months back and cut them in, but was instantly sick of them. They're long enough now to sweep to the sides a bit or to be pulled back by a head-band, so I do that a lot. Judging from your pic I bet they look pretty good on you :)

to post pics you need a photobucket or other type of photo hosting website account. set one of those up and they should give you a code to post your photos in forums - easy to cut n paste it in. or if youre copying from a myspace page or somewhere else you already have photos posted, right click on the photo, and copy the photo location. then in the post use this code [ IMG] before the address and without the space and then  [/ IMG] after, again with out a space in it.

Ahh yes I have gone through this experince several times myself! The easiest and cheapest thing for you do is get a set of clip-in bangs that you can layer into your own since as I understand it you are only wanting extensions in your bangs. Don't waste your money going to a professional for just that little section, its honestly not worth it. Here is an example of what I'm talking about and a tutorial on how you could also make yoru own and how to put them in.

No extensions will make your own hair longer unfornately, so you will still need to fiddle with your own bangs and do your best to straighten them so they blend in. But they should grow to a length where you can do that more easily fairly quickly. In the mean time you could try getting some velcro rollers (of various sizes so you can figure out what works best) so they get a more uniform look. I know being curly how frustrating it can be to get them to lay flat, so I'd add a heavier anti-frizz type serum to that section of your hair, see if weighing it down slightly can help flatten it out
hope this all helps, let us know if you need any more help!
