hahaha sure I'm a little high right now but here goes. Not much to say. It's a balloon that gets implanted under the skin behind the hairline. It's kind of a kidney bean shape to contour to the natural shape of a hairline. Attached to this balloon is a little dome about 1" diameter connected to the balloon by a tube. Kind of like the top right model here, only the tubing should be connected to the concave aspect of the kidney bean. This device is implanted through a 3-4" incision at the hairline. It is implanted under the galea, which is the fascia that connects the muscles of your forehead to the muscles of the back of the head. This means it is implanted DIRECTLY AGAINST YOUR SKULL. YOU WILL FEEL AND HEAR METAL SCRAPE ACROSS YOUR RAW SKULL while the doctor is stretching open this space and pushing the balloon into place, under only local anesthetic. It's a pretty weird experience. I was pretty sore after. I posted on this site I think I was eating around 80 mg oxycodone a day in the first 2 days. It reminded me a lot of jaw surgery pain. Very strong. Now, I can have a family member insert a needle through my scalp, through my galea, and into the "port" of the device which is at my crown, and inject water. I'm supposed to inject 20 mL twice a week until I reach around ~450 mL. 450 mL! That's like a water bottle! This balloon is going to get huge! It's a pretty hilarious surgery really. I plan on wearing a fedora to cover it when it gets really bulbous. Then after I reach full volume, the surgeon will knock me out, take out the balloon, stretch down my hairline, cut out around 3.5 cm of forehead, and then stitch me back together. That's basically the whole deal. I have put expansion on hold as I'm waiting for the rest of my hair to grow back first. There's no rush really once the expander is in. It can just sit for months if needed. At least so I'm told. Here's an example of a good forehead reduction outcome: It's meant for people born with too high a hairline, not to correct hair loss.
