Gibson, 55, is seeing deep recession in the temporal region as well as thinning across his hair line - nothing uncommon for a man his age.
The best course of action for him would be to start a regimen of Rogaine or Propecia to help prevent or slow down further recession. His thinning hair would also benefit from Low Level Laser Therapy treatments.
These simple and non-invasive steps could help Gibson feel a lot more confident as he plans his return to the spotlight.
