Hiya, I think I can help you here. I've had that hairstyle for a while now in different lengths and all sorts.
When I went to the hairdressers I didn't go prepared with pics (they won't know what you're on about! lol) and it didn't go great.. but they tried really hard to get it how I wanted, but yeah.. get lots of pics! and really emphasize about loads and loads of layers and starting them short. It's not common for them to cut hair like that (I may of just gone to a bad salon though *shrugs*..)
About the fringe.. it will be fine. It does look cool will it being a bit longer and you can get lots of razored points in the fringe as well and have it to the side a bit. But I wouldn't worry too much.
And it will suit a round face. But you can customized the hair line and fringe to suit yourself best anyway.
Have you considered cutting your own hair? It's pretty easy with this cut if you buy a razor comb (I just do my own now) plus layers need cutting back in to keep it looking all pointy and sharp at the ends so it saves trips to the hairdressers.
Go on youtube and type "how to cut an asian mullet" and there's a few good vids to give you an idea of how it's done. Then follow
this guide as well if you're up for giving it a try.
It's probably an idea to go to the salon initially though, then you can experiment with layer lengths and keeping on top of it at home.
I brought my razor comb from boots. They're so easy to use! Plus a pair of hairdressing scissors to just finishing it off or for a quick trim on your fringe.
It really helps to have thick hair for this style. Mine is a bit finer texture but I wouldn't just totally not have this style if you're hair is fine, it will just gives a softer look.
Hmm what else.. (as if this isn't long enough
)
Ah if you go ahead and get this hairstyle you should get a good hair product. I use gatsby. It's a Japanese product and they're sooo good for defining the layers and giving lift. I use the green air-rise one and they sell them on ebay last time I brought some.
I think I rambled(?) lol sorry. Feel free to ask me something if I totally missed the point.
