Success rate of facial/beard hair transplant or any cosmetic surgery is largely dependent on the doctor or clinic that consistently produce successful results.
This is a problem when the direction was placed in the wrong angle. You may have to get FUE on those hairs that are misplaced and then re-implant them in the proper direction.
If you are having issues after surgery, especially with "redness" you should contact your doctor. It may be a sign of infection. It may also be normal. It is best to contact your doctor for treatment options.
