Well, the hair grows in phases, and electrolysis only is used on the hairs that can be grabbed so I would think you would see a reduction in those areas but with only four months I would think a fair bit of hair that had been in dormant stages wouldn't have been zapped yet. Everyone is different, but the little electro I have had done seemed to do nothing unless that area was cleared quite a few times due to hair in dormant stages.
Have you thought about laser, it is a fair bit cheaper you might still need electo afterwards for light hairs, but it would be a fair bit less electro needed saving a fair bit of cash.
