Very rough skin/poor yield after hair transplant. Is this normal? (Photo)

Thank you for the photos.  Are you prone to hypertrophic scarring?  This isn't the typical response from a HT. It is possible the grafts were placed improperly.  I'd recommend an in person evaluation with a board certified physician.  

Redness and cobble stoning is not normal especially after 8-9 months.  A second surgery will not improve the skin.  You need a proper exam and diagnosis of what happened from the first surgery or you may repeat the mistakes in the second surgery.

For things to improve.  You should give it time and make sure to follow post op care carefully.

What you describe is highly unusual. It is not attributable to the method of donor harvesting, but rather to the technique used for preparation of the grafts and creation of the recipient sites. You could see a dermatologist, but it is unlikely there is any effective treatment for your situation. 

There are many factors that cause poor growth and pitting , the most important is poor grafting technique and surgery by the doctor and the staff. It is still too early to evaluate the result of your second surgery.
