I've posted this before in the past. It's where they tie individual strands of hair to your growing hair. You get 4 "cyberhairs" per strand they tie in. It seems like it might be good to fill in my front. I don't have bald patches there...just very diffuse thinning. I keep saying I'll make an appointment for the cyberhair thing, but I never do it. I should at least go to the free consultation, but it would mean going to a hair replacement place. I'm scared.
