Why do I still have bald areas 8 months post hair transplant? (photos)

It is hard to tell the reason, it relates to how many grafts you had and how many actually survived in the transplant process. Best to see your transplant doctor to know the real reason.

first of all I have to see preop photos .You may have a cicatricial alopecia , so do you have a skin biopsy before ? The most outstanding reason for poor growth and ineffectual hair restoration results is insufficient number of viable graft placement as a result of intra operative damage of follicular units ( during insertion or high transection rates during harvesting, long time of grafts out of body, dehydratation, poor FU storage/handling conditions like high room temperature, storage fluids etc.)
