I had eyebrow implants done 18 months ago. I have a lot of gaps and want more hair added to fill them in. I am planning on having another procedure done to have 300 more grafts added to each side which is going to cost me another $5K. I already spent $7K for the first procedure. Would it be ok to have my aesthetician do microneedling to brows and add a growth factor instead to make them grow? Or would that harm the implants I have? Thanks!!!
