Only answers from Stylist or those who've had extensions please..?

If you start layering your hair before putting the extensions in, it would look better and you would be more "safe". If you put the extensions in and started layer your hair then, your extensions could fall out OR once you take the extensions out, your naturtal hair would have a weird un even layering to it. I think you should layer it first then put the extensions in. Goodluck.
