How to get rid of small lumps in root of hairs after hair transplant 6 years post? (photo)

If it's been over 6 years, it probably would not get any better.  Scars from surgery is very difficult to treat.  The first step would be to see a doctor for an examination.

you can not get rid of small lumps in roots of hair because it is related with implantation technique that was wrong .İt mostly due to deep implantation of hair roots and fraxel laser, cortisone shots, and dermabration may help in a small extension.

These bumps you are talking about appear like bits of elevated graft skin from the original transplant. These bumps occur when the surgeon uses larger grafts, leaves too much skin on the edge of the graft or does not flatten the graft to the skin surface at the time of the surgery.

Hello
These are typical surgical problems where the skin around each grafts has not been trimmed down totally. These are seen , so i would not blame the doctor too much, one of the reasons they are more visible is the colour of your hair, If you had darker hair, it would not be too visible. One way of camouflaging these is to get more hair put it. I have seen more such problems with FUE compared to FUT, since in FUE, surgeons are resistant to trimming skin, while in FUT skin trimming is done for all grafts. LASER is an option, using CO2 or Erbium, but you will have to trim your hair temporarily
