@Felthry electrolysis takes forever to actually kill the folicals but the hairs come out Bella easily just by pulling on them after a few sessions. It can be very painful, though, depending on which hairs are being done
Laser is more efficient and I don't think the pain is as bad as the worst electrolysis gets, but you need naturally black hairs for it to work so rip if you don't
You will absolutely need pubic hair removal for GRS tho
