You can easily trim off the excess lace---ALL lace systems come with about a half inch width of ` excess` or ` spare` lace all the way around the perimeter...this is easily trimmed off with a small sharp scissors....some guys like to trim it so that there`s still a millimeter or so of lace in ` front` of the hair....other`s [like me ] go right up to where the hair ` begins` .....it`s quite simply done.
As for cutting the hair ----- I would NOT attempt this ----a stylist spends a number of years learning their trade to cut and style growing hair ----systems are not much different from a head of growing hair as such, but many stylists will not oblige and do a cut-in for fear of the ` unknown` or being held ` responsible` for ruining a system should the end-result not be to the person`s satisfaction. Debbie has many years experience in doing systems and her charge is reasonable...... you may find that a local stylist will demand a ` premium` price from you for a cut-in and the result may not be very satisfactory.... Debbie can at the very least, do the main part of the styling and layering-in and any ` tweaking` can be done easily with less stress by taking a trip to a local stylist..many stylists will happily do a little ` adjusting` for you once the ` heavy` work has been done.....
It`s your choice, but my advice is NOT to attempt a cut-in yourself..you`ll most likely ruin it and end up out-of-pocket and disappointed.
