Ridge and excess volume in recipient area after hair transplant. Any suggestions? (photos)

A bad hair transplant scar is hard to fix. FUE will not "debulk" this area. It may make it worse.  See a doctor for an examination and possible options.  Steroid injections may be an option.

It's really hard to tell from the photos if the ridging is from the transplants or just normal. Many people who've never had an HT have what you are calling riding. It's just a change in the density of the sub dermal layers of the scalp and you can see and feel this throughout your scalp. It may well just be the way you were born. You really don't see significant ridging from modern day hair transplants. That's really the result of massive scarring from large graft implantation, usually the plug variety wherein they actually punched out recipient areas leaving massive holes deep in the skin rather than just making a slit. These large insults caused a tremendous scarring response that resulted in elevation of that area by as much as a quarter inch or even more. If you really dislike the elevation your best bet may simply be to implant modern follicular units (single hairs) in front of the ridge to block it. I will make your HT look better as well. Check out a local HT doctor about that plan and get back to use her on Real Self. Best.

Ridging is a problem for many of the older types of grafts. This is a problem because the grafts are large and the bulk of these graft lift the skin up with it. A good doctor might be able to see if there is a hypertrophic component of this and then suggest a treatment such as intraluminal steroids, but this will not work if the ridging is the result of large graft bulk.
