what is this called for cancer patients?

i've had this type of weave done..and love it!  i heard it's been done for cancer patients..i now have a full head of hair (shoulder length) and have had this type of weave done for a few years...when i first came to the beautician, i was half bald thanks to monkey barzz, great lengths, and gawd knows what else...i had a lot of hair loss due to a few newbies out there, who had good intentions, but wound up using me as a guinea pig...until i was a bald guinea pig.

i'm looking for a beautician more close to home..she braids my hair up, then places and sews a hairnet on top of the braids.then sews the wefts on in a criss cross fashion.  what is this called? i live in the bay area.

 have most definitely have heard of that and even tried it on one of my clients.  The name that I know it by is called 'net weaving'.  It's just another way to do a full cap weave, but you only do one circular cornrow around the head by the hairline and that gives you a base on which to sew the net.

A man named Clem Lue Yat teaches it and he has a salon in New York where they perform this service.
