Stocks are `standard`..the specifications are shown on that `stock ordering `page....medium density is standard on them as is the base-material [all- French lace OR all- skin] .... all systems whether stock or custom, will have to be cut-in by a stylist--stock hair- length is 6-inches, but on a custom, you can order what length you require... it`s always preferable to have it done while it`s sitting [bonded] to your head in a stylist`s salon....if you can`t find a stylist in/near your area who`ll oblige, you can have the system [stock or custom] sent to Debbie for a `remote`cut in..... you can liaise with Debbie through her site/ e-mail on what you require [pics of yourself/head and style you`d like will help her greatly] I think she charges about 40$ or so .... have a look at her site [ services link] for full information.
http://splitendshairreplacement.com/ but as I said [and Debbie also say`s it] not everyone will find that `remote` cut-in suitable--many `ordinary` stylists will be happy enough to `tweak` a system in terms of blending/thinning where the hair joins/meets your growing hair, provided the ``Heavy-work`` has already been done, as in having it styled remotely by a professional like Debbie....If you choose to have a remote styling done,you should measure your bald/thin area front-to-back and side-to-side to get an approximate measurement...stocks are 8 x10 inches ....if it needs to be `cut-down`[the base] Debbie can do that too....be aware that a stock may not fit snugly around the perimeter due to the contour/shape of your individual head...as stated--stocks are a `standard`size/shape--- you may find some `uneven` or `bunched-up` bits on the perimeter.....some guys get a great fit with stocks, others not as good ...custom is best in those cases, but sure, stocks are good to `tide you over`if you`re in a hurry ..just don`t expect the same high standard as custom, in terms of fit, but you may also be pleasantly surprised and find it fits like a glove, but generally, they are a middle -of-the-road solution.
All systems are just made at the factory.....styling and cut-in`s are a matter for the wearer to arrange.
