My scalp was chemically burnt, I still have bald spots. 31 years old what are my options for a full head of hair again? (Photos)

Hi there, 
I'm sorry to hear you are going through a tough time with your hair. If you hair has not regrown after 12 months following your burn you may benefit form a hair transplant to cover the areas of concern. I would suggest you see a hair loss specialist who can assess your history and scalp. All the best.

We truly feel your anguish.
Certainly see a hair specialist. Scaring is difficult to overcome. It is likely some or most of the affected follicles are dead.
However, you might consider PRP therapy and possibly adding some extracellular matrix (ECM) prior to a transplant. The PRP will help regenerate what is possible and the ECM will help additionally with the scaring. Thus possibly being able to regain more hair.
You will likely need to be a bit more patient than the average person to overcome so much. That which does not return and will not cover easily will likely need to be transplanted. 
Using the PRP first may allow you to reduce the number of transplants and thus the cost. As well the ECM will certainly make the transplant areas a much more fertile area for transplants.  
Wishing you all the best and great success in finding a remedy to your situation.
Warmly,
Arbella Sarkis, MD
