Pluggy hair. Is it easy to remove?

Pluggy hair or bad hair line hair transplant is hard to remove. That is why you need to select your doctor wisely.  One way to address a bad hair line is to add more hair (in front) to cover up the bad pluggy hair.

I am disappointed to hear that your transplant did not provide you the desired results. You might consider a second hair transplant treatment and, if so, I recommend NeoGraft - the first and only FDA-approved transplantation treatment that removes individual hair follicles from the scalp and places them in scalp areas where balding is occurring. It is the least invasive procedure for hair transplantation with minimal bleeding and fewer complications than the procedures performed by the "strip" method, which you may have experienced.I suggest you consult a board certified facial plastic surgeon
because the board certified credential ensures you receive the highest
quality knowledge, treatment, care and skill available. A consultation provides
you the opportunity to relay your concerns and desired outcome to the surgeon
while the surgeon can assess your health profile and discuss his/her pertinent
advice.

Yes, you  may have a few options and the first  best thing is to first talk to the original doctor as most hairlines can be adjusted.

The hairline is classically developed using single hair follicular units. The 2 and 3 hair grafts are placed for density.  Speak with your hair-restoration surgeon regarding your result. Possibly, the single grafts have not grown enough to camoflauge the double and triple follicular unit grafts.  Best of luck from Manhattan.

If you have some questions about the quality of your hair transplants, possibly noticeable grafts that show up detectable, then go back to your doctor and ask about it. See what he will do about it.
